Most of the members of this genus are tender, but sepiaria (syn. japonica) may be grown out of doors in mild districts. It is a beautiful spreading deciduous shrub, with prickly stems and large racemes of yellow flowers with prominent red filaments. It blooms in spring. It should be given a fertile, friable soil.
Vulgaris is the common Ling or Heather, which grows so abundantly on the peaty uplands as to form a carpet. White Heather is particularly esteemed. Searlii (or Serlei) and Hammondii are two good white forms. Argentea, aurea and cuprea have coloured foliage. There are many other varieties. The Callunas are closely related to the Ericas, and are often grown under that name. Although peaty soil is desirable it is not essential.
Nurserymen offer wolgarica, a deciduous member of the Pea order, growing about a yard high, with yellow flowers in early summer. Ordinary soil.
Floridus, the American Allspice, a deciduous shrub, was referred to in Chapter 18. C. praecox is the same as Chimonanthus fragrans, which was alluded to in the same chapter. These deciduous, piquantly perfumed shrubs are most at home in the angle of two walls.
