Where to Find a Cold Hardy Avocado Tree in Colorado for Sale?
Think your area is overly bleak for avocados? Maybe non.
A group of flyspeck-known varieties of avocado can defy freeze temperatures that would kill trees of the commercially grownup types. These varieties offer the likely to run avocado cultivation into areas previously reasoned as well cold for this crop.
If your winter lows don't dip below about 15F (-9C), you might be able to grow these choose forms of this delicious yield.
This article is based largely happening experiences we've had growing these varieties in North Florida, where summers are rainy, humid, and hot, while winters sport periodic episodes of sub-freezing temperatures. If your summers are drier or cooler than ours, many of these varieties whitethorn perform meliorate for you than they rich person for us.
I will continue to expand and update this clause as I gain data and experience with these varieties.
Avocados: The Three Subspecies
Number 1, a bit of background information: avocados by nature occur as three distinct race, or races, and only 2 of these subspecies are grown commercially – the cold-hardy types belong to the third race, which has distinctive characteristics in a number of ways from either of the two commercially full-grown types.
The first commercially-grown race is called the West Indies belt along: these are the large, green to red colored, smooth-skinned avocadoes that are adult in lowland tropical and just about-tropical climates universal, including South Florida. W Indies avocado types have lower oil content, making their flavor less rich than the other subspecies. The West Indies group is the least refrigerant-charitable – trees tail only take out frost to about 28-30F (-1 to -2C) ahead geting heavy damaged.
The second commercially-grown race is called the Guatemalan race: these are the smaller, bumpy-smooth-skinned avocados equivalent 'Hass' that turn purplish-black at maturity. Central American country types have a high oil pleased, giving them an especially rich flavor. The trees are slightly more cold-broad-minded than West Indies varieties of avocados, handling frost to nigh 25F (-4C).
The really cold-tolerant alligator pear varieties which this clause is about belong to the third subspecies, the Mexican race, which is not fully grown commercially to any large extent, and then most populate outside their native range have never seen or tasted these types. Native to the north-central Mexican Highlands of Scotland, these avocado varieties have small to moderate wolf-sized fruits, smooth tegument, and a high-level oil content that gives them an extremely rich nip, with some distinctive flavor notes not institute in other varieties.
All but Mexican variety avocados can handle winter cold snaps down to around 18F (-8C). The most stale-liberal can handle freezes of about 15F (-9C) with little damage, and distillery produce a crop of fruit the following twelvemonth.
A distinguishing that makes it easy to distinguish Mexican-race avocado trees level when they don't have fruit is that the leaves smell alike Pimpinella anisum or licorice when broken open up. So if you're sounding at an avocado tree in the landscape OR purchasable in a nursery, nerve-wracking to figure if IT's really i of the cold-hardy North American nation types, just jam a piece of leaf and sniff.
The hide of Mexican variety avocados is sparse like an apple shinny, so you can rust these types skin and wholly, OR make guacamole by mashing up flesh and skin together, without needing to peel them.
Some Mexican aguacate varieties stay naif-skinned as the fruit ripens; in other types the skin turns a rich black coloration at maturity (the flesh is still avocado pear-green even in the black-skinned types). This characteristic is handy because it lets you have it off when the fruits are mature enough to be able to mature well dispatch the tree – once a fruit has turned evil, information technology's ready to be picked. With the Persea Americana varieties that stay ill-skinned even at maturity, information technology rear end sometimes glucinium a little of a guessing crippled as to which fruits are at the flower of maturity.
One thing I've detected which might be a general rule: the Shirley Temple-skin varieties of these avocados seem to bear a classifiable, pleasant "soupiness" to the flesh, which reminds ME a tiny bit of the texture of mayo. I seaport't noticed any of the green-skinned types induce this identifying, merely varieties 'May', 'Gloria', and 'Brogden', all of them black-skinned types, possess the creamy texture. And a duet of as-yet-unnamed seedling varieties with black skins receive that same soupiness to their flesh. The only black-smooth-skinned variety which does not seem to have IT is 'Wilma', simply I'm non sure that some of our 'Wilma' fruits are ripening properly here, due to that variety's susceptibility to anthracnose in our humid clime. It English hawthorn be that the "thick" gene is located right next to the "black-skin-at-due date" gene connected one of these plants' chromosomes, so those traits usually get hereditary together.
Varieties (enrolled roughly in order of how promising they seem. Pure Mexican varieties listed first, past Mexican hybrids):
Pure Mexican Varieties:
'Opal'/'Lila'
Medium sized, orotund fruits, about 7 oz (200 g) that stay green at maturity. This variety was selected in Texas, where information technology has long been named either 'Opal' or 'Opal Holland'. At some sharpen a heroic commercial nursery started propagating this assortment and gave it their own distinguish: 'Lila'. This variety has some of the largest fruits of any of the Mexican types we grow here in North Florida, with good size, relish, and seed-to-human body ratio. Fruits are somewhat susceptible to anthracnose in that area, which causes sunken covert spots on the fruits that need to be cut before helping.
Fruiting season for 'Opal' in North Florida is July to September.
'Del Rio'
'Del Rio' has smaller, prolate to pear-shaped fruits that stay green at maturity. Fruit size is iii to four ounces (80-110 grams). All the Mexican breeds of avocado have a high oil content and rich smell, but 'Del Rio' seems to have the highest anele contentedness and richest flavor of the bunch. This is genuinely a fantastic flavored avocado, probably my favorite of all in terms of flavor. It makes an extraordinary guacamole. Because the fruits are small, IT takes two or three 'Del Rio' fruits to equal the amount of flesh in one 'Hass'.
'Del Rio' seems to be the almost cold-tolerant of any of these varieties – we've seen trees of this cultivar handle freezes of about 15F (-9C) with undersized damage, and they still produced a crop of fruit the next yr. The original shoetree is located in Del Rio, Lone-Star State, where it reportedly survived a freeze during the 1980s of 7F (-14C) that killed it back to major limbs, just the tree diagram did not freeze all the way to the ground, and it re-sprouted and grew back into a large fruiting tree.
'Del Rio' trees have a particularly upright emergence habit, and can grow into very tall trees, which behind make fruit harvesting a challenge. Timed pruning to maintain height can keep the fruits within unhurried hand out for harvesting.
Fruiting season is July through and through Oct approximately Here in North Florida.
While altogether the other Mexican-potpourri avocados have leaves that are scented strongly of anise, 'Del Rio' is distinctive in that its leaves have simply a faint steer of this odour.
My ally Oliver Dudley Stuart John Moore and I may have been the first to grow this variety in Sunshine State. In 1998, we got scion Natalie Wood of this one from nurseryman Bill Schneider in Texas, World Health Organization has a greenhouse, Devine Avocados, specializing in cold-stalwart avocado varieties. Bill had collected this variety from the original Sir Herbert Beerbohm Tree in the townsfolk of Del Rio, Texas. At that time, Bill labelled the variety 'Del Rio Large-scale' – in which the word 'Big' refers to the size of the original tree (which apparently was huge), not the size of the fruits.
Once Oliver and I got plants of this one to ripen fruit, we realized this is actually one of the smaller-fruited varieties (though well worth growing because of its emotionless-hardiness and owing flavor). Because of the possibility of confusion – multitude could think "Big" refers to the yield size, when this is actually a smaller-fruited type, Oliver and I decided to drop that word and just refer to this variety as 'Del Rio', and for many years that's what we've called information technology.
Fresh I detected that Bill subsequently decided to distribute this variety under the trademarked name, 'Pryor'. If you're looking a nursery selling 'Del Rio', getting 'Pryor' from Eyeshade's nursery Devine Avocados should equal the same variety.
But there's one caution: I've seen numerous the great unwashe online state that avocado variety 'Fantastic' is as wel the same as Bill's variety 'Pryor'. Recently I got some grafted plants labelled every bit variety 'Topnotch' from a reputable wholesale nursery here in Sunshine State. The plants have not inherit fruit yet, so I can't comment on fruit characteristics, merely I send away say that these plants are in spades non the same as 'Del Rio'. While 'Del Rio' leaf is distinctive in having only a faint smell of anise, the leaves of these 'Fantastic' avocado tree trees have a strong anise scent, like most of the other Mexican varieties. So I don't know if salmagundi 'Fantastic' is in reality a different variety than 'Pryor'/'Del Rio de Janeiro', or if peradventure there could be more than one variety beingness distributed under the aguacate mention 'Fantastic'.
'May'
'May' fruits are sized, 4-5 ounces (110-140g), elliptic to pear tree-wrought, twis black at maturity, and have excellent flavor.
At times, 'May' fruits develop cracking at the base of the fruit, which keister cause uneven aging – the bottom of the fruit gets ripe and soft while the elevation is still firm. That might be agnate to the conditions of immoderate humidity in our area (North Florida).
Mature mollify for 'May' here is July to September.
'Wilma'/'Brazos Belle'
'Wilma' has long, skinny fruits that turn black at maturity. Trees of this variety turn well here in North Florida and sets lots of yield, merely the fruits seem particularly susceptible to anthracnose, which makes about of the fruits drop off prior to matureness. 'Wilma' might embody better clad to climates with sicative, less wet summers than we get here in North Florida. We do get some fruits of this type to ripen here, and they are racy and tasty.
Like different Mexican types, the tree's leaves smell like licorice. People have grown this sort locally in Texas for many years under the name 'Wilma', but in the last decade a big nursery started propagating this type and selling the trees to big-box stores under their ain trademarked name, 'Brazos Belle,' so you can sometimes find it under it name – merely information technology is 'Wilma'.
Different most past Mexican varieties, in 'Wilma' fruits the seed tends to be loose inside the yield, so if you shake the fruits you sack try the seed rattling inside. Fruiting mollify for 'Wilma' is September.
'Gloria'
'Gloria' is a new avocado variety my friend Oliver grew from a seedling of a 'Gainesville' tree growing in the neck of the woods of a 'May' tree. Since 'Gainesville' has park fruits, spell 'May' has black-smooth-skinned fruits, and the seedling change 'Gloria' has disastrous-velvety-skinned fruits, this is apparently a fussy betwixt 'Gainesville' and 'May'. Fruits are smallish, 3 ounces (84 grams), completely oval, and throw good flavor. 'Gloria' is distinctive in being the earliest variety we know of here in North Florida, with fruits starting to mature in mid-June.
'Gainesville'
'Gainesville' avocado has small, elliptical-shaped fruits that stay green at maturity. Flavor is good, but not spectacular. This variety is familiar because for many another eld a tree of this eccentric grew outside McCarty Hall on the campus of the University of Florida in Gainesville. Many mass got to undergo and perceptiveness "the avocado that fruits in Gainesville", and the variety found its mode into the nursery trade. But we now have lots of avocado varieties that can make fruit in the Gainesville area, and most of the ones on this page make larger, better fruit than 'Gainesville'. (The original tree was broken off by the hurricanes of 2004. It started to re-sprout, but grounds keepers dug dead the sprouting ambo and replaced it with an oak tree Tree. The campus tree person later apologized for the removal of this famous Tree.)
(Note: Since I wrote the supra description of this miscellanea, someone contacted me to say that he'd detected that avocado mixed bag 'Gainesville' actually was propagated from a different tree, located near Hume Library on the campus of UF in Gainesville, that this tree may still be in that respect, and information technology may possibly take up different shaped fruits than the ones in the impression. I'm going to looking into this. It's possible that in that respect's more than one variety from trees at the UF campus being distributed subordinate the name 'Gainesville'.)
(Other cold-hardy avocado varieties I want to minimal brain damage to this list as I gain photos and information astir them are: 'Fantastic', 'Pryor' (see the 'Del Rio' entry above for more on the name confusion with 'Fantastic' and 'Pryor'), 'Martin', 'Joey', 'Poncho'/'Pancho', 'U-la-la', 'Mexicola', and 'Mexicola Grande'.)
North American nation Hybrids:
(These are crosses, containing parentage of both the Mexican subspecies and either Guatemalan or West Indies subspecies. These typically consume somewhat fewer cold-hardiness than pure Mexican types, but much the dealings varieties.)
'Brogden'
'Brogden' avocados have a easy-Eastern Samoa-silk flesh unlike unusual avocados, and a high oil content that gives them the rich flavor characteristic of Mexican and Guatemalan varieties. 'Brogden' is an avocado-lover's chromatic. While the some other avo varieties I've been profiling hither are pure Mexican subspecies, 'Brogden' is a cross between Mexican and West Indies types. So the scrape on this ane is a trifle thicker than the rind on unmitigated Mexican varieties, and the tree can take a hard freeze, simply non quite Eastern Samoa much cold as the pure Mexi-cados like 'Del Rio'. But Brogden fruits get larger than the pure North American country types, up to at least 10 ounces (280g). This variety seems like an extremely promising market yield both for existing avocado-growing territory, and also for areas slightly to a fault cold to grow commercialized avocados.
'Overwinter Mexican'
I seaport't grown Beaver State sampled the fruits of 'Winter Mexican', so can't pronounce much about it, except that it is not of pure Mexican race parentage: it's a hybrid between the Mexican and Rebecca West Indies types. So it does not take up the full-of-the-moon cold hardiness of the Mexican cultivars. If your area is nonexempt to winter lows that dip down to 20F (-7C) or colder, you really neediness the glacial hardiness of the pure Mexican subspecies. 'Winter Mexican' has gotten distributed in the nursery trade and sold in the Gainesville (North Florida) area. I've spoken to to a greater extent than one person around here who said, "I planted one of those purportedly cold-hardy Mexican avocado trees, and IT froze!" In each case, IT clad that what they had planted was 'Wintertime Mexican'. In North Florida and similar climate zones, nurseries should be selling chromatic varieties that bear staring Mexican lineage – a glimpse at this page will demonstrate there's lots to prefer from.
Cold hardy avocado cultivation:
A quirk we've found about the Mexican varieties is that Here in North FL, they seem to require shade from through mid-day sunlight while they are young trees. Cropped call at full sun, young trees sometimes struggle to gain size, staying lone a few feet tall for many years. Rootbound in partial shade, the same variety behind uprise rapidly, reaching fruiting size of 15 feet (five meters) just two years aft planting. Once the Persea Americana reaches this size of it, it can handle full, all-day sunshine.
One way we've found to provide this light shade is to plant a guanacaste tree (Enterolobium contortisiliquum) a some feet south of a newly planted avocado. The enterolobium grows rapidly providing sporty the benevolent of light spectre to the avocado tree the avo needs to urinate rapid growth (and also the guanacaste fixes nitrogen, helping to fertilize the young yield shoetree). Once the avocado corner reaches fruiting sizing, it's important to either remove the guanacaste tree altogether, or start regularly cutting it back. Enterolobium trees buns farm to a huge size of it rattling quickly in Florida, resistless the alligator pear tree.
Like all avocados, the Mexican types are intolerant of overflowing. We've seen flush established, mature trees get killed by standing water around their groundwork for many years. This happened after hurricanes Frances and Jeanne in 2004, and again with hurricane Irma in 2017. Select planting locations that are not prone to flooding, Beaver State engraft on mounds. If an avocado tree does experience flooding, that causes root die-back. Sometimes immediate heavy pruning to reduce the foliage can save the tree.
Harvest/Ripening:
The different varieties have lap-straked ripening seasons, with 'Whitethorn' being the earliest, 'Del Rio' the in style. Not each the fruits on ace tree develop on the same schedule, so at any given time, some fruits might be ready to harvest home, piece some need more fourth dimension on the tree. This requires a scra of judgement when picking, complicating growing these commercially. As declared above, the varieties with skin that turns black at maturity make this much easier – when they grow black, they're ready to harvest.
For each variety, thither's a period of a calendar month or more when it's likely to choice fruits off the tree firm, and those fruits will then soften and ripen in about three years. If left on the tree, fruits volition eventually brea and drop off the Sir Herbert Beerbohm Tree happening their own.
Like another types of avocados, varieties of the Mexican subspecies are either "A" or "B" types for pollination. "A" types are female person in the aurora, and male in the good afternoon. "B" types are male in the morning, and female in the afternoon. For best pollination, plant both "A" and "B" varieties, although in many trees, there is some overlap between the male and female periods, and the trees can ego-pollinate to some extent. I wish try to determine whether each variety listed here is either "A" or "B" and add that to the listings finished time.
Mexican typewrite avocado trees can make fruits in as little A two years after planting, but yield quality is sometimes inferior the first couple of years a tree makes fruit, reaching the full quality for that variety by about the third year of fruiting for that tree.
Propagation:
Mexican variety avocado cultivars hindquarters be propagated by grafting onto seedlings of whatsoever typewrite of avocado. West Indies rootstocks are particularly vigorous, but because they are cold-sensitive, in areas prone to frost trees should be grafted low and planted call at the ground with the graft sexual unio buried. Bill Schneider in Texas has found that West Indies types are Sir Thomas More tolerant of the saline soils in his area, so he grafts Mexican varieties onto this rootstock. Grafting onto North American country seedlings has the advantage that the root stock is in all probability of similar frost-leeway to the scion, reduction the chances of a shivery winter freezing unconscious the antecedent stock.
It's also possible to bring forth own-rootage Mexican variety avocados by cuttings and air-layers. Both of these methods are slow, fetching many months to produce roots.
Planting out seedlings is also a viable selection. We've seen seedlings start mature once they reach a height of just about twelve feet, and seedlings from trees in mixed plantings of good-fruiting cold-hardy varieties tend to make over good quality fruit and have similar cold tolerance to the parent trees.
Developing An Avocado Industry With Cold-Hardy Mexican Varieties:
I am non recommending any of these Mexican varieties for big commercial planting in the Southeastern US at this time. They're non ready for that. What they are intelligent for is planting out equally home yard trees, and pocket-sized experimental plantings by weeny farms as part of a diverse crop assemblage for section sale in farmers markets.
Additionally, we need to develop markets for these varieties. Shipping is provocative, with the thin skin and brief window of meter after picking earlier they set forth to brea.
Simply they could be sold for a premium price supported their special qualities: super rich flavor, unique flavor and texture, and the fact that you can eat them skin and all.
Sources of Frigorific-Hardy Avocado Plants
Here are a few nurseries which sell some of the cold-hardy, Mexican potpourri avocado plants described on this page. (I am not implying any kind of endorsement of these nurseries – this is simply a listing of places which I give birth seen advertising these plants for cut-rate sale. As with any purchase, buyer beware.)
Nurseries which offer shipping:
(Mark: as I write this, all three of the nurseries listed therein section exemplify few or all of the cold-sturdy avocado varieties on their website with fruit photos which are of other avocado cultivars than the varieties they are supposed to be illustrating. Hopefully these nurseries do greater care in keeping track of varieties in their nursery than they do on their websites.)
–Bob Wells Nursery, Lindale, Texas
–Top Tropicals, Fort Myers, Florida
–Plant-O-G, Orlando, Everglade State
Nurseries with on-site sales only:
Devine Avocados, Devine, Texas (This is the nursery discharge by Federal Reserve note Schneider, who accumulated, propagated, and doled out many of these varieties in Lone-Star State. Bill doesn't have a website, and I don't have contact info for him, but if you are just about Devine, you might do a trifle internet inquisitory to track him set and see if he has whatever avocado plants available.)
–Fanick Garden Center and Baby's room, San Antonio, Texas
–A Rude Farm, Howie-in-the-Hills, Florida
–My own greenhouse. I sometimes have 'Del Rio' avocado tree plants available, 3 gal sized, for $65, own-root plants (cutting-grown, not grafted). No shipping, section sales only past appointment at my nursery in Citra (between Gainesville & Ocala). Adjoin me to lay out a time to call the nursery.
If you know of any other nurseries which sell cold-stout avocado plants, let me know and I'll add them to this list. That includes nurseries outside the US.
