Herself's Houston Garden

Conservation through cultivation

Thryalis Galphimia gracilis




This shrub will easily reach 6′ tall in Houston and 4′ across. It is a very dense shrub right down to the ground. There’ll be no bare legs hanging out underneath.

Thryalis prefers full sun, it will grow in part shade but it’ll get leggy on you.

Blooms prolifically mid spring to early winter.

Drought tolerant once established. Excellent for barriers and low maintenance areas.

Birds, bees and butterflies are attracted to this plant.

Hardy to zone 8 but will die back in the winter in zone 8.

This did not survive not sure if last summer’s drought, this winter’s freezes or a combination of the two is responsible.

Propagate by cuttings.

Sometimes referenced as thryallis

Nothing interesting to report yet, this plant is only glancingly referenced in my books and I just picked it up this week.

Note: One of very few survivors of the drought and heat of summer 2011
