Ray florets: corollas white or bicolored, proximal ¹ / 3 - ² / 3 of laminae white, the rest purplish to reddish, pinkish, or bluish. Disc corollas 2.5-3.5 mm.

Pericallis hybrida has escaped from cultivation and is established in the cool, damp climate of the San Francisco Bay region. It is a complex of true-breeding cultivars derived from wild progenitors native to the Canary Islands (T. M. Barkley 1966); it is not a naturally occurring species. The cultivars are widely grown in glass houses and are sold as cool-season pot-plants in the horticultural trade.

The name Senecio cruentus (L´Heretier) de Candolle has been widely misapplied to Pericallis hybrida in the horticultural trade.
