Chinese Primrose: Primula sinensis
Tender greenhouse perennial that is grown as a greenhouse annual in temperate areas. It has bright-green, lobed, tooth-edged hairy leaves. Flowers, 1–1 ½in (25–36mm) wide, are borne in clusters from midwinter to early spring. Some have frilly edges. Colors include white, pink, red, orange, and purple. Like Primula obconica, the leaves can cause rashes on arms and wrists, especially when damp.
