The annual varieties of candytuft are favourite edging flowers for beds and borders. They are of various colours, crimson, rose, lavender, purple flowers, etc. The plants are of the easiest possible cultivation and make a brave show for several weeks. Seeds are sown in April where the plants are to bloom in summer and the seedlings should be thinned to about 6 inches apart.
There are some charming flowers among the perennial candytufts. They look best in the rock garden, where they will drape the boulders with sheets of bloom in spring. They flourish best in well-drained soil and should be planted in autumn or spring. The best sorts are Iberis sempervirens, garreyiana, and gibraltarica. all with white flowers. One named Little Gem is of compact growth and suitable for small rock gardens. Cuttings taken in June and placed in pots of sandy soil in a frame will soon form roots.
