The schizanthus, or butterfly flower, is a greenhouse plant that blooms abundantly in summer. The best results are obtained by sowing the seeds under glass in September and repotting the seedlings as is necessary, finally placing them in 7-in. pots. They develop into fine plants and bloom in May and June. Seeds may also be sown in the greenhouse in spring. There are many varieties. The colours include rose, orange, and lilac, as well as white.
