ERYSIMUM Alpine Wallflower

The Wallflower is one of the most popular of all spring-flowering plants for the bed or border, but its dwarf alpine relative is an uncommon rockery plant. You will certainly be able to recognise it when in bloom – it looks like a miniature version of the ordinary yellow Wallflower in every way-leaf, growth habit and flower shape. An easy plant which will grow in any open sunny situation, but it is not long-lived.

VARIETIES: Some species of Erysimum grow to 1 ft or more, only E. alpinum is a rockery dwarf – height 6 in., spread 6 in.

Flowering period: April-May. The fragrant, yellow blooms are about V2 in. across. A number of named varieties are available if the bright yellow colour of E. alpinum does not appeal, but choose with care – some are quite tall. ‘K. Elmhurst’ (lilac) may reach 1.5 ft and ‘Moonlight’ (primrose yellow) grows taller than the species. You are safe with ‘Jubilee Gold’ – it only grows 6 in. high.

SITE AND SOIL: Any well-drained, non-acid soil will do – thrives best in full sun.
