Although this is a greenhouse perennial, fresh plants are invariably raised as annuals, flowering from early winter to late spring. Clusters of flowers, 1in (25mm) wide, appear in pink, red, lilac, or blue-purple. The light-green, oval to heart-shaped leaves form an attractive backdrop for the flowers, but can create painful rashes, especially on wrists and arms, especially when damp.
