DELPHINIUM

Hardy perennial Nearly all the perennial varieties may be raised from seed, and where large numbers are required this is the best method of obtaining them. They make handsome border flowers, and are extremely valuable during the early months of summer. Sow in May,



June or July, in the open ground, and transplant in autumn. If mixed seed has been sown, it will not be wise to thin out all the weakly plants, or it may happen that some of the choicest shades may be lost. The first flowers will be over by midsummer, but if the stalks are promptly cut down instead of being allowed to seed, there will be a second display later in the year. Three varieties, Queen of Blues, Dwarf Porcelain Blue, and Blue Butterfly, may be flowered as annuals, by sowing in pans in March and transplanting to the open as soon as the seedlings are ready. They also make particularly charming pot plants, for which purpose it is advisable to sow seeds in March. The scarlet variety (D. nudicaule) is rather more delicate than the others, and it is wise to raise the plants in well-drained seed-pans, and to take care of them through the first winter in a cold frame; indeed, in a heavy soil there is a risk of losing them in any winter which is both cold and wet. It is not necessary to employ pots, but immediately after flowering take them up and store in peat until the following April, when they can be returned to the open ground. D. sulphureum. The seed takes a very long time to germinate, and severely taxes the patience of the sower. But otherwise there is no difficulty in raising plants, and the long spikes of beautiful clear sulphur-yellow flowers are well worth the extra time the seedlings need. The best plan is to sow in autumn in the open ground, cover with a frame, and avoid disturbing the soil, except for weeding, until the next autumn, when the plants should be put into position for flowering in the following summer. As slugs are exceedingly partial to Delphiniums, the crowns should be examined in spring, and the seed-beds may be dressed with soot and surrounded with ashes to save the seedlings from injury. The annual Delphiniums are dealt with under Larkspur, page 274.
