Cymbalaria
Family: Scrophulariaceae
From western Europe, these creeping, herbaceous perennials can be grown as groundcover but are invariably short lived. Sometimes they are grown as potted indoor plants. They have small, lobed leaves and spurred flowers in summer.
Species
C. hepaticifolia, a trailing species to 2.5 cm (1 in), produces purplish lilac flowers in summer.
C. muralis, variously known as Aaron's beard, Kenilworth ivy, pennywort, ivy-leafed toadflax, mother of thousands and climbing sailor, zone 3, grows to 1 m (3 ft) and, depending on the variety, produces lilac, pink, white or blue summer flowers. It is a pretty plant but considered a weed by some.
Cultivation
Plant in a shady spot and provide plentiful moisture. Sow seed in a normal potting niix in spring and fertilize every three months during the growth period. Good drainage is essential. Whether grown outdoors or in a pot, Cymbalaria is best suited to a temperate climate. Spray foliage of indoor plants with water during the growing season. C. muralis often appears as a volunteer, especially in cracks of walls or paving.
Climate
There are species suited to various climatic zones.
