V. MINOR.--Lesser Periwinkle. This is of much smaller growth than the preceding, and differs, too, in not having the leaf-margins ciliated. The variety V. minor flore-albo has white flowers, those of the normal plant being pale blue; V. minor flore-pleno differs in having double blue flowers; V. minor foliis aureis has golden-tinted leaves; and V. minor foliis argenteis bears silvery mottled and very attractive foliage. They are all of simple growth, succeeding well in somewhat shady situations, and in by no means the richest of soil. As they run about freely and soon cover an extent of ground they are rendered of great value for a variety of purposes. VITEX. VITEX AGNUS-CASTUS.--Chaste Tree, Hemp Tree, and Monk's Pepper-tree. A South European shrub (1670), growing from 6 feet to 10 feet high, with digitate leaves that are almost hoary beneath, and spikes of small violet flowers. It is not very hardy, although in some of the warmer parts of southern England and Ireland, fair-sized, healthy-looking specimens are now and then to be met with. As a wall plant, however, it succeeds best, and for which purpose, with its neat foliage and pretty flowers, it is peculiarly suitable. VITIS. VITIS HETEROPHYLLA HUMILIFOLIA.--Turquoise-berried Vine. North China and Japan, 1868. The leaves of this Vine are three to five lobed, and the small flowers freely produced in slightly branching cymes. The latter are succeeded by their most interesting and attractive berries, that ripen in September and October. They are pale china-blue, marked all over with very dark specks. The stems grow to a height of 4 feet to 8 feet, and should be trained against a wall in a sunny position to ripen the berries. The plant is perfectly hardy. The variety V. heterophylla variegata is a dwarf, low-growing plant with variegated leaves, and is used for pot work, for covering the ground in sub-tropical bedding designs, and might be used to great advantage for rambling over large stones in the rock garden.
