There is but one species of perennial Candy Tuft generally known among us, and this is deserving a place in every garden, which is Iberis tenoreana. This plant is half shrubby at the base, with delicate linear foliage, and is covered with a profusion of its pure white flowers, in umbel-like corymbs, in June and July. The stems are rather decumbent and spreading; about six inches high. The plant is propagated by layers or cuttings. It is not inclined to make itself too common, like some plants; for, unless special pains are taken, it will not increase.
