South African bulbs

Haemanthus Deformis in Flower!

It’s been quite a while since I posted anything about my houseplants, and given that Sioux City’s been getting snowy, frigid weather this past week, it feels timely to take a look at a beautiful flower and urge on spring’s arrival!

As you may recall, I have two Haemanthus deformis bulbs in a single pot. It’s a very striking and unusual plant. I believe my bulbs are both approximately seven years old, and they have flowered before. So far they’ve not flowered at the same time, such that I’ve been unable to attempt pollination. Hopefully someday! While there are haemanthus species that are relatively quick to offset, H. deformis is not, so getting viable seeds would be an exciting development.

Right now, one of my H. deformis has been blooming for a couple of weeks! The flower is very low in the plant, which is not atypical though there are images online of some with higher peduncles (and greater age can play a role in that as well). The bulb that is blooming is letting its old leaves die back while focusing on its flower, but will then grow a new pair of leaves (you can see the beginning of one to the right of the bloom)!.

If you’re curious about their care, they spend the warm weather outside in light shade (usually early May through early October), and come inside for the colder seasons where they bask under grow lights. They get watered once every week or two, occasionally with weak fertilizer.

Most haemanthus are deciduous, but H. deformis is one of the evergreen species. I keep four haemanthus species at present, and it’s a 50-50 split between deciduous and evergreen in my collection. Of those four, this species is my favorite! I love its outrageous leaves; they usually fully cover the whole top of the pot, so to water I have to gently lift a leaf up to sneak the watering can spout in beneath it!

Haemanthus Deformis

I like growing South African and Namibian bulbs. There are some commonly grown ones you’ve almost certainly encountered - amaryllis, clivia, ledebouria, oxalis - and types that are rarer. The genus haemanthus is one of my favorite of these geophytes, though I keep a variety and am quite drawn to ledebouria as well.

Within the genus of haemanthus, I started with the moderately common Haemanthus pauculifolius a few years ago (though I ordered Haemanthus albiflos from Glasshouse Works, but they’re very similar and easily confused so they must have mislabeled their specimens), and I was pretty quickly charmed. I added three rarer species from Shire Bulbs to my roster last year: Haemanthus crispus, Haemanthus humilis subsp. hirsutus, and Haemanthus deformis.

This winter, all four of my haemanthus species are doing well, but my two Haemanthus deformis bulbs have been a particular delight to watch as they’ve settled in and are now growing mature leaves for the first time with me. H. deformis leaves are showstoppers! They have a kind of alien quality to their size and growth habit - you can already see the appeal in the photos below, but the leaves should get even bigger and more tightly flush to the surface with age. The first image is how the bulbs arrived in December 2021 after I’d potted them, and the second two images are of them this winter - with some surrounding plants included to provide a sense of scale in the second photo. (The white marks on the leaves are just mineral deposits from watering.) You can see that I already needed to pot them up again this fall.
