Description
Cornish heath is an evergreen subshrub, growing to a height of . The small linear leaves with pale undersides and down-rolled margins grow in whorls of four or five on the wiry stems. The inflorescence is a fat, leafy spike with a few long-stalked, globular flowers; these are pink or lilac and have brown stamens that protrude from the open mouths. The flowering period is from July to September.
Cornish population
In Great Britain it is only found on
the Lizard peninsula in southern Cornwall, where the
unusual geology gives rise to the
acid soils

that it favours. It was voted the
County flower of
Cornwall in 2002 following a poll by the wild flora conservation charity
Plantlife. It is often considered the
Cornish floral emblem. According to one story this is because when
Joseph of Arimathea first arrived in Cornwall looking for tin he had nowhere to stay, so he spent his first night on a bed of Cornish heather. In thankfulness, he blessed the plant and it has been a blessed plant ever since.
Cultivation
Like almost all plants in the heath family (Ericaceae), ''E. vagans'' requires an acidic or, at the very least, neutral soil to thrive. In areas with alkaline (basic) soil, this can be achieved by planting ''E. vagans'' in containers with ericaceous compost. Numerous
cultivars have been developed with a range of flower colours in white, pink, mauve and purple.
