The annual Larkspurs are familiar to almost every one. Some of the species and varieties are among the most common ornaments of the garden. They are all very hardy, and flower stronger when self-sown in summer, or planted in beds, or in,the border, in August or September. There are two distinct species in common cultivation, differing essentially in their habits.
Delphinium consolida. - Branching Larkspur. - This variety grows from two to three feet high, producing its flowers in spikes, which are continually pushing out from the main stem and branches, giving an abundance of bloom through the season. Flowers blue, white, pink, and variegated. The double varieties are the most desirable. Masses of the different sorts appear to great advantage.
D. ajacis. - Dwarf Rocket Larkspur. - The double varieties of this species are among the most showy ornaments of the flower-garden, when properly grown.
A bed of the double varieties, consisting of white, pearl color, lilac, pink, light and dark purple, is equal in beauty to a bed of fin 5 Hyacinths. Autumn-sown plants will grow from one and a half to two feet high. When grown in a rich, stiff soil, the Rocket Larkspur must always be considered the greatest summer ornament of the garden. The seed should be sown in beds where it is to remain, as it does not succeed well when transplanted. The plants should be thinned out so as to stand six inches apart.
