The daisy-like flowers of the calliopsis (or coreopsis) are orange, yellow, crimson, and brown, growing on stems l,5 - 2 ft. high. The annual varieties are sown out of doors in March - April, where they are to bloom in summer. Several kinds are perennial, but as they are liable to perish after having flowered it is wise to sow seeds annually in June; the best are auriculata superba, grandiflora and lanceolata, all three bearing yellow flowers.
