Propagated by seeds in a moist hot-bed in spring.
Acanthostachyum. Bromeliaceæ.
Propagated by suckers, which strike readily in bottom heat.
Acanthus (Bear’s Breech). Acanthaceæ.
Propagated by seeds sown in gentle heat, or by division of the root in autumn or early spring. Also by root-cuttings. Water carefully.
Stocks are grown from stratified seeds, which should be sown an inch or two deep. Some species, as A. dasycarpum, come readily if seeds are simply sown as soon as ripe. Varieties are often layered, but better plants are obtained by grafting. The Japanese sorts are winter-worked on imported A. polymorphum stocks, either by whip or veneer grafting. Varieties of native species are worked upon common native stocks. Maples can also be budded in summer, and they grow from cuttings of soft and ripe wood.
Aceras. Orchideæ.
Propagated by carefully made divisions of the tubers. (See under [Orchids].)
Aceratium. Tiliaceæ.
