Delphinium (Larkspur)

The gorgeous spikes of flowers produced bythese plants render them invaluable for the border. They like a deep
soil, highly enriched. The perennials may be divided at the root in
autumn, care being taken not to injure the young fleshy sprouts. The
annuals are readily raised from seed. The quickest way to grow the
perennial varieties from seed is to sow in a frame with a slight
bottom-heat, at any time from March to August; but sowings made in the
open from April to June will succeed. Keep the ground moist, and shade
from the sun till the plants are up, then transplant to nursery beds
for the summer, afterwards transferring them to their final quarters.
Flower in June and July. Height, 1-1/2 ft. to 6 ft.
