C. INTERMEDIA ROSEA (Bonamy).—An erect-growing ornamental sub-shrubby Clematis, which, though attaining about six or seven feet in height, is not of climbing habit. The leaves are variable in form, but approach those of C. Viticella, being often pinnatisect, with the ovate-oblong leaflets decurrent behind. It is a free-blooming plant, with bell-shaped horizontal or nodding flowers, large as compared with those of most of the non-climbing species, of a pleasing lilac-rose colour, the sepals being broad and mucronate. The flowers altogether bear much resemblance in form to those of the Viticella group; and are developed effectively above the foliage in branching panicles of eight or ten together; so abundant indeed are these in the adult plants, that they have the appearance of a huge bouquet. The plant is suitable for low walls or trellises, or for furnishing the naked trunks of trees occupying prominent positions. The variety is a seedling from C. intermedia, which was itself a chance seedling in the nurseries of MM. Bonamy, of Toulouse, and is supposed to be a natural hybrid between C. integrifolia and C. Viticella coerulea. See preceding paragraph [Clematis intermedia]
