Description

Exceptional in every way, the only white-flowered member of the rosinweed tribe is rare in the wild and even rarer in horticulture.  Large white daisy-flowers open in summer above clumps of raspy and rabbit-resistant leaves that resemble those of compass plant (Silphium laciniatum), but on a smaller scale.  This beautiful thing from hot gravelly Texas prairies is perfectly hardy here in Zone 6.

Sun; deep well-drained soil (drought tolerant); 30"x24"; summer; Zone 6

Propagated from seed; deep 3.5-inch pots
