the following being some of the best: C. vulgaris alba, white-flowered;
C. vulgaris Hammondi, C. vulgaris minor, and C. vulgaris pilosa, all
white-flowered forms; C. vulgaris Alportii, and C. vulgaris Alportii
variegata, the former bearing rich crimson flowers, and the latter with
distinctly variegated foliage; C. vulgaris argentea, and C. vulgaris
aurea, with silvery-variegated and golden foliage; C. vulgaris
flore-pleno, a most beautiful and free-growing variety, with double
flowers; C. vulgaris Foxii, a dwarf plant that does not flower freely;
and C. vulgaris pumila, and C. vulgaris dumosa, which are of small
cushion-like growth.
