Family: Scrophulariaceae
Common Name: Mask Flower

This genus of about 12 species of evergreen shrubs, subshrubs and perennials, native to Peru, is gradually becoming more widely grown. They have small leaves on erect stems and trumpet-like flowers in the summer and autumn. The flowers are quite curious, for the trumpet appears to be twisted upside down. In frost-prone Climates alonsoas are mainly used as annuals for summer bedding.

Cultivation
