Apocynaceae
Very pretty hardy, herbaceous perennials, with alternate leaves, and terminal panicles of pale blue flowers; corolla with linear lobes, and a narrow funnel-shaped tube. They thrive in half shady positions in borders, or the edges of shrubberies, where they will not need to be frequently transplanted. Propagated by cuttings during the summer months, or by divisions of the roots in spring.
A. latifolia. (broad-leaved). Synonymous with A. Tabernaemontana. A. salicifolia. (willow-leaved).* fl. light blue, in terminal corymbose cymes; corolla small, funnel-shaped, with a rounded tube; throat whitish, bearded. Summer. l. lanceolate, smooth, acute. h. 1 1/2ft. to 2 1/2ft. North America, 1812. Habit less erect than the following species.
A. Tabernaemontana (Tabernaemontana-like).* fl. pale blue, in cymes; petals lanceolate, acute, slightly hairy on the outside; sepals also lanceolate, acute. Summer. l. ovate-lanceolate, acute, shortly stalked. h. 1 1/2ft. to 2 1/2ft. North America, 1759. SYNS. A. latifolia, Tabernaemontana Amsonia. AMYGDALUS (from amysso, to lacerate; fissured channels in the stone of the fruit). Almond. ORD. Rosaceae. TRIBE Drupaceae. Well known, ornamental, deciduous spring flowering shrubs. Drupe clothed with velvety pubescence, with a fibrous dry rind, separating irregularly, having the stone of the fruit pitted or smooth. The larger-growing species are very excellent for shrubberies, or as specimen trees; being in blossom before most other trees, they make a fine appearance in early spring. The dwarfer kinds are also well fitted for small shrubberies or the fronts of large ones. For greenhouse culture they should be obtained in a small pyramidal shape; they are not, however, suited to a small house, as the plants, to bloom well and be effective, ought to be at least 2ft. or 3ft. high, and proportionately wide. Plenty of root room is essential. After potting, water thoroughly, and place the trees in an orchard house for a few weeks, when they may be removed to their permanent station. A temperature of about 50deg. or 55deg. is sufficient to hasten the flowering a higher temperature is apt to frustrate the object in view. After flowering, gradually harden off the plants until about the end of May, when they may be plunged out of doors for the season. Repotting should be done as soon as the leaves fall. Increased by budding upon seedling plum-stocks in summer. The Almond is grown on the Continent for its fruit. See also Prunus.
