Great plant for the heat. I grow it outside in z8b and I have a friend who grows it in 7a so I think the Z rating is too conservative above. It is a short lived perennial. I get 2-3 years put of it.But they do seed nicely and I am never without them.

These are fickle in Albuquerque New Mexico 6b-7a. Is my lack of blooms lack of water or toon much shade?

I cannot say enough nice things about Nierembergia! Beautiful rich color, perennial in Zone 7, fern like foiliage, creeps over walls and fills in areas. Lovely. Low water.

Cupflowers are a fabulous choice for a mixed box or bed - they do not stamp out other plants, but come back year after year as strong bloomers. Initially bright, dark purple, the blooms fade to pastel lavender by the time they are spent. Deadheading them at this point brings on more blooms.

Grows well even in West Texas. Zones 6, 7, 8, 9. Hardy, stands up well to high, hot winds and climates with little rainfall ( 12-18 inches per year). Some supplemental water during droughty weather. Do not allow roots to stand in wet soil for long periods of time. Like well drained soils.

Beautiful showy flower for semi-arid climates.
