There is a difference between the Eglantine, or Sweetbrier, and the Dog-rose, although they are difficult to distinguish. "The 'Dog Rose' sends up long arching branches some six to nine feet high and perhaps more; the 'Sweetbrier' is content with branches three or four feet in length. And whereas in the 'Dog Rose' the branch continues single the 'Sweetbrier' sends out side growths, or branchlets quickly forming a dense bush. Note also the prickles. To a certain extent they are stout and hooked like those of the 'Dog Rose,' but more irregularly placed. On the young root-shoots there is a marked difference, for whilst on the 'Sweetbrier' this young growth is covered with _setæ_, some of them very small, tipped with glands, in the 'Dog Rose' they are totally absent."[96] [96] Pemberton, "Roses" (London, 1908). ROSEMARY. Tender, aromatic sub-shrub with small flowers in short racemes. Propagate by seeds, cuttings, or layers in dry, light soil. The flowers are purple and bluish. Rosemary is valued in cookery as a flavoring. It can be allowed to wander all over the garden. It was always a favorite border-plant in old-fashioned gardens. RUE. The "herb of grace" is not very pretty. It has much divided leaves and panicles of small fragrant flowers, yellowish-green, or greenish-yellow. Propagate by seed and division. Rue needs a sheltered position and protection in winter. Its height is about two feet. SAVORY. Sow in open ground at the end of March, or early April, in light, rich soil. Thin the seedlings moderately; they may remain where they are, or be transplanted. Sown along the outside of beds, savory makes a good edging. It is useful in cookery. SWEET BALM. _Melissa officinalis_ is the botanical name. Sweet balm is loved for its fragrance. The yellowish white flowers bloom in June, July, and August. It grows about two feet and loves the sun. Propagate by seed and division. SWEET-WILLIAM is a valuable little garden plant, for it blooms profusely in June and July and is vigorous and rapidly spreading. The flowers are in double clusters, pink, white, red, and party-colored, single and double. Propagate by seed in any soil. See Carnations. THYME. This aromatic herb is of dense growth with small, pale-lilac flowers in terminal spikes. Its pale, bright-green foliage makes it an attractive creeper for banks. Thyme also grows well in a rock-garden and makes a good border-plant also. Propagate by seed and division. The plant grows in any soil. It attains a height of from one to two inches and blossoms in June and July. Every one knows the value of dried thyme for flavoring in cookery.
