Aloes going at it at Boyce Thompson Arboretum

Post Number:#1  Postby mcvansoest » Sat Jan 06, 2018 9:06 pm

My wife and I took some friends visiting from Canada to Boyce Thompson Arboretum on Jan. 2nd and we very impressed by the multitude of flowering Aloes. So any Aloe lovers in the VOTS now is the time to go take a look!

Here are a bunch of pictures I took while there - unfortunately many are unlabeled so I am not always clear on the ID, I will note it where possible:

Nice post, mcvansoest! I've been trying to decide whether or not to make a trip out there tomorrow to see the aloes. You might have just pushed me over the fence!

They sure have a lot of nice stuff...seems I should try A. rubroviolacea. The second photo kinda looks like hereroensis, but flowers are really early and it's not typically a clumper. 8th is cryptopoda/wickensii.

Plants for the southwest here in Tucson has (or had) a bunch of A. globuligemma. It's supposed to be a good plant for heat and sun with some moisture. We'll see...

Yep, I got slightly greedy when I saw all those big Aloes looking good and in bloom. Of course BTA is not the VotS... some plants that do great up there will probably struggle a bit in my yard. It gets hot there in summer, but not quite like the valley.

Also saw that Aridlands has a bunch of small globuligemmas.

Those higher elevations a good home for A.plicatilis or the tree Aloe's?...Great variety there. I like the A.rubraviolicea too. Its a standout at the UC Berk botanical garden.

I do not think they have plicatilis, might still get too dry and too hot even at BTA in summer. I tried a 10 gallon plant once and kept it alive long enough to get flowers, but once summer hit whatever I did it just started a downward spiral and eventually succumbed. I know that some people grow it successfully here, but you'd almost have to think they do it in a climate and sun controlled green house and by that I mean with cooling in summer...

I think it is an Aloe for slightly less long duration extreme heat and dryness...

Other tree Aloes sure, but gotta be ones that can take the low-mid 20s as it can get pretty cold there at night, if we hit the low 30s they are sure to hit the mid 20s. So far this year there has not been much of that at all.

Kinda hard to tell from the photos, but can you comment on the sun exposure for any of them, especially the tree aloes? I have seen the large trees from the highway on my way up to Globe, and it looks like a lot of them are getting quite a bit of shade?

MitS, I'd say they get a lot of shade for sure. Given that it is winter, they probably see a little more shade now compared to summer, and for sure they are in the more wooded area of the creek, but most are on the south facing slopes, so do get some decent sun exposure for part of the day. Almost all get good protection from the low angle late afternoon summer sun.
