(aka: Phemeranthus rugospermus A5TX-029) Phemeranthus rugospermus is a rare, little-known US native (Minnesota south to Texas) fameflower. It has a wide range, growing natively in dry sandy soils and rock outcrops. Rough-seeded fameflower an absurdly hardy succulent that forms a small plant to 10" tall x 10" wide, composed of a succulent stem and fleshy, succulent tubular leaves. The insanely drought tolerant clumps are topped in June/July (NC), with 5-petalled, purple flowers, which open only for a few hours each late afternoon. Phemeranthus rugospermus can be confused with Phemeranthus parviflora, but the stamen count 12-24, vs. 4-8 makes it easy to distinguish. Our offering is propagated from our Anderson County, Texas collection, near the extreme southern end of its range.
