Mangave zombies

One of many great attributes of mangaves, compared to one of their parents, agaves, is that they don’t die after flowering. Agaves are mostly monocarpic, which mean that they behave like bromeliads, where each rosette grows to maturity, then dies after flowering. Those species of agave which offset, live on after flowering, by means of un-flowered offsets. Those agave species which don’t offset are a one and done after they flower and reproduce by reseeding.

By incorporating manfreda genes to create xMangaves, the monocarpic trait disappears. After a mangave flowers, it dies to the ground, but like a good zombie, it soon pops back from the dead. Here is a current photo from the garden of two clumps of xMangave ‘Blue Mammoth’. The first, larger clump has not flowered, but should do so next year. The second clump with all the offsets, flowered in 2020, and re-grew to this point in 2021. Next year, the rosettes will continue to re-grow in size.

The Purple Passion Mystery

Last year, we saw a listing for a new Mangave, M. ‘Purple Passion’ on the availability of a West Coast liner producer, so we ordered some to try. It was immediately evident when we unpacked the shipment, that the plants didn’t look anything like a mangave, nor did what we received match the image that the supplier had on their website.

As we dug deeper, we found that the supplier had misappropriated a mangave image from another wholesaler and was using it for the plant we purchased, desptie the two looking nothing alike. Once the image issue was remedied, we set out trying to track down the origin of this strange plant, which looked more like a steamrolled eucomis than a mangave.

The supplier sent us to their supposed source, who had never heard of the plant in question. For six months, we have chased down one lead after another, contacting all of the well-known plant breeders of these type of plants on the West Coast. All dead ends.

Examining the plant in our garden this summer, it occurred to us that the unusual leaf netting must have come from a beschorneria. Comparing the foliage netting of ‘Purple Passion’ to beschornerias in our garden yielded a perfect match, except for the leaf color. The only plant which could have been crossed with a beschorneria to give such leaf color is a manfreda. Hence, our conclusion that our plant is in fact a new bi-generic hybrid, x Beschfreda ‘Purple Passion’ (beschorneria x manfreda).

Since we don’t know which species of beschorneria was used, we are uncertain about potential winter hardiness, but with plants in the ground now, all we need to do is wait for cold weather. Below is a photo of the plant in the garden this week. If you happen to know more of the backstory of this fascinating plant, please let us know.

Riding the Wave

Looking nice this week is this cool selection of the North American (Northern Mexico) native Manfreda undulata. All commercial forms of this are heavily spotted, but we really love this this amazingly rippled-leaf form that we picked up at Bob Brown’s wonderful UK nursery a few years ago on a UK plant roundup trip. We’ve named this seedling, Manfreda ‘Crested Surf’. Hardiness should be from Zone 7b south.
