Erysimum: Wallflowers are a harbinger of spring and provide a familiar sweet scent

摘要

Wallflowers, always popular as bedding plants, were once widely available as bare-root plants. But now the fashion is for more compact plants, ideal for six-pack and 9cm container production and therefore for the garden centre trade Breeding has given us varieties to flower in autumn, spring or winter, making them very versatile. Because they are easy to grow, the amateur seed market is still buoyant, though new genetics are making the more advanced seed expensive for commercial growers.
