Mangave Follies
I've acquired a modest collection of Mangaves over the last few years-most of them are still in pots but I am slowly transitioning some of them to the ground. The advantage with pots is that it's easier to move them out of harms way in winter, which as it turns out is a must-do for some cultivars. Some are also apparently a gourmet treat for snails. I bought most of those that I have collected from the UC Davis Arboretum plant sales-they had them back when nobody else did. This year though I opted to hold off buying any more until I have a better plan for winter . I saw inconsistent reactions to rain and cold so a year to just to shift plants around and observe the results seemed like a wise choice.
The rainy season of 20-21 has featured (so far) only 8.19 inches of rain (season normal in the 25" range) and lots of frost with typical early morning temperatures in the 29 to 32 range. The coldest temp I registered here was 24f . It's not unusual for us to get rain in March/April and sometimes even May-I'm hoping for at least 5 more inches, still well below normal. All to say my Mangave results might vary in a normal year if we ever have another one.
Exhibit A is the sad condition of Mangave 'Kaleidoscope'. It looks only slightly worse than it did after the previous winter-one would think I would have taken evasive action this year but instead I potted up the largest pup last summer and and placed them in separate locations to see how they fared. My intention has always been to give it a home in the ground but that is looking more and more unwise. I was so excited to find this plant which had long eluded me at, of all places, an otherwise mundane Armstrong Garden Center in San Juan Capistrano on a road trip a few years back. It was the only one, looking sad (not as sad as it looks now) with a couple of broken leaves and burnt tips.It received no protection from rain or frost, and you see the results below.
Mangave 'Kalidescope' in it's winter best.
The pups fared much better-the pot lived close to the west wall of the house and was occasionally covered with frost protection. So later this spring I'll repot this and give it both rain/frost covers all winter. Because we are having a Socal-esque rainy season I believe frost and temps in the mid to high 20's are the real culprits.
'Spotty Dotty' began to show some damage early on , and was moved to the covered front porch for the duration. Might be candidate for in-ground living if protected from rain---and snails. With a little rearranging I could easily fit several Mangave containers on the front porch next winter.
'Crazy Cowlick' spent the entire winter up against the southwest corner of the house under the Acca sellowiana.It was in a rain shadow which seemed to serve it well, but being in the shade didn't do much for it's color/spots. It will be gradually introduced to the sun.
This unfortunate specimen is 'Pineapple Express'. This is it's 2nd winter in the ground -each year in a different spot. The new spot this year was likewise not a success, though it was bermed for better drainage.
Pineapple express number two, fared much better, however it was shrouded all winter by the allegedly deciduous Spirea 'Ogon' . I really love this Mangave so I need to figure out a spot where I can actually see it-I moved some branches out the way to get this photo-the lower left is pretty much normally invisible. It will be another that needs both a rain and a frost cover.

One of the more disappointing outcomes is 'Lavender Lady' which was looking beautiful and pristine in it's container until those 20's hit. I had planned a move into the garden for it this spring -though I am still predictably indecisive about where that spot might be. It seems that cold is the issue here-we got significantly more rain last winter with no ill effects for this one. A frost cloth is an easy solution.
'Purple People Eater' has been in ground for two winters, and the only ill-effects occurred when we had a prolonged frost with a low of 24. Even then the damage wasn't too bad. If I'd thrown a frost cloth over it the tip burns probably could have been avoided. I'll be more vigilant in the future.
Mangave 'Moonglow' got a spot next to Meliathus 'Purple Haze' just out of view to the left.
'Man of Steel' needs to get out of this pot. Must be about 10 pups in there and not a touch of winter damage. I will likely pot up a couple of those pups separately as insurance in case the move doesn't work out.
'Bloodspot' indeed ushered my entry into the world of Mangaves (in 2015). I didn't find another one until 2 years later. I've had better luck with them in my warmer, frost-free environment, although I recently lost one, 'Barney', soon after planting it in the ground. It was a Christmas present from a friend, who found it at a big-box store, which is the only outlet I've heard of that offers it. I haven't been able to find anything on its parentage and I'm perplexed by its rapid demise. I had it in a pot in the spot I planted it for a good month or more before I put it in the ground so I don't think it was a temperature problem - I'm guessing that the rain, little as we've received, is responsible for turning it into mush.
ReplyDeleteIt seems like they like a little more moisture in summer than an Agave , but could do without winter rain..but 'Bloodspot' and 'Moonglow' don't seem to care one way or the other. I'm looking forward to trying a couple more in the ground this summer.
DeleteHere in Austin, 'Macho Mocha' was the gateway into mangaves. It was widely available a number of years ago and of course totally fabulous -- and winter hardy, most years. 'Bloodspot' is popular too, and also pretty winter tough. I've expanded since then, but always in containers, since our winters are unpredictable. The neighborhood deer found my 'Pineapple Express', even in its tall pot, and grazed it to nubs, but it recovered when I moved it behind my fence -- until I accidentally left it out during the Texas deep freeze. I have fewer mangaves now, but I love them. Such a great-looking group of plants!
ReplyDeleteI have yet to see 'Macho Mocha' in any nursery here. It must have been available at some point since I'm pretty sure Gerhard has one. Sorry to to hear that you lost 'Pineapple Express' in the snowpocalypse. Interesting that the deer liked it--the snails love mine but we've had so little rain this winter the snail pressure has been almost nil.
DeleteLike me, you've got enough successes going to keep you on the hook with these addicting plants! They are starting to be readily available locally, and I wouldn't walk away from a 4-inch plant for sale but am steering clear of the usual $50 they go for until I get the hang of what they like.
ReplyDeleteAll of mine were 4" Denise, so I'm not out much if they bite the dust. They grow pretty fast in my experience, especially if they are in the ground.
DeleteI too am wondering what conditions they want. Will try one out front in full sun and see what happens. Here more worried about dry heat than cold/wet.
ReplyDeleteI worry about full sun too Hoov, especially if we have the barrage of heat waves we had last year. Some cultivars have so many offsets I could try them in different spots.
DeleteForgot to mention, my 'Kalidescope' doesn't look much better. No frost here, so I think the problem was too wet, leading me to speculate it wants winter dry.
DeleteMaybe they just need total rain protection. I'm going to put mine in a rain shadow next winter
