Bifid Rhodophiala

The genus rhodophiala is in a state of flux. Some taxonomists believe the genus actually doesn’t exist and should be merged with rain lilies, while others consider it a perfectly valid genus with 27 species. Oh, the joys of taxonomy. To most gardeners, the genus rhodophiala are simply dwarf hippeastrum (horticultural amaryllis), the most commonly grown of which is the South American Rhodophiala bifida, which ranges natively from Southern Brazil into adjacent Argentina.

Rhodophiala bifida starts flowering for us in mid-August, alongside the emerging foliage. Most Rhodophiala on the market are the clonal Rhodophiala bifida ‘Hill Country Red’, brought to the US by German born Texan botanist, Peter Henry Oberwetter circa 1890. This clone is virtually sterile when grown alone, but will produce viable seed when grown adjacent to another clone.

Below is the clone ‘Hill Country Red’, followed by some of our selected seedlings, all photographed here at JLBG over the last couple of weeks. The best conditions are full sun to light filtered shade, and average moisture to dry soil.

Rhodophiala bifida ‘Harry Hay’ seems to be the only named clonal selection grown in the UK. We imported this during our 2020 UK trip.

Rhodophiala bifida ‘Carmencita’ is our first named introduction, released in 2017.

Below are two fascinating plants from our breeding. The first is a cross of Rhodophiala bifida x Lycoris longituba. In theory, this bi-generic cross shouldn’t work, but the flower arrangement sure resembles a lycoris more than a rhodophiala.

This cross is of Rhodophiala bifida x Sprekelia formosissima is another impossible bi-generic cross. Notice the three petals are one size, and the other three petals are larger. We’ve never heard of this happening in rhodophiala, so perhaps we’re on to something.

The only other Rhodophiala species, which we’ve had any luck with is the Chilean Rhodophiala chilense. Below are two forms, both of which flowered this spring.
