S. vulgaris Alphonse Lavallee, with full double red flowers, changing to mauve. " Emile Lemoine, mauve-pink, suffused with white; very handsome. " La Tour d'Auvergne, mauve shaded with rose. A beautiful and very dark coloured form. " Lemoinei, nearly resembling our common species, but with full double flowers. " Leon Simon, light pink, mauve shaded. " Madame Lemoine, the finest form, bearing very large pure white double flowers. " Michael Buchner, rosy lilac. " Virginité, whitish pink, nearly white when fully expanded. President Grevy is one of the same beautiful group. The blooms are large, double, and produced in very massive clusters, and of a light bluish-lilac tint, when forced almost white. The first of this group, S. vulgaris Lemoinei, was sent out about 1884, and was then awarded a certificate by the R.H.S. The range in colouring of these Lilacs is rather confined, so that the various forms resemble one another in no small degree, particularly when the flowers are opened under glass. From the large size of the flower bunches, and the individual flowers being double, they are all of great beauty, and being quite hardy still further enhances their value for outdoor gardening purposes. The Lilacs grow freely in any soil of fair quality, but a free, rich, and not too dry loam, would seem to suit the majority of these plants best. TAMARIX. TAMARIX GALLICA.--Common Tamarisk. India to Europe. This shrub often in favoured maritime places reaches to a height of fully 10 feet, with long and slender branches, and spikes of pretty, rosy-pink flowers produced at the end of summer. For sea-side planting, it is an invaluable shrub, and on account of its feathery appearance and wealth of showy flowers is well worthy of being included in our list of ornamental and useful shrubs. T. PARVIFLORA (_syns T. africana_ and _T. tetrandra_), South-eastern Europe and Levant, is a nearly allied species, with white, pinky-tinged flowers. TECOMA. TECOMA GRANDIFLORA (_syn Bignonia grandiflora_), from China and Japan (1800), is not so hardy as T. radicans, although in certain maritime districts it succeeds fairly well. The flowers are very attractive, being of a rich orange-scarlet, and produced in drooping clusters. Both foliage and flowers are larger than those of T. radicans. It wants a warm, sunny wall, and light, rich, and well-drained soil, and if only for its lovely flowers, it is well worthy of coddling and good treatment.
