Temperature is also of little consequence. Anything above 50° at night will do; but it is best not to flower them in a higher temperature than 60°, or they will quickly wilt when cut or used for decorations. From the time the sprays begin to show white color until they are fully developed, every astilbe should stand in a saucer in which there should be constantly an inch of liquid manure. When sold for window plants or for decoration, astilbes are often disappointing. It is merely want of water. Before the full development of the shoots and leaves, they are easily hurt by tobacco smoke, and should be covered with paper or well wetted when fumigation is necessary. Aphis, spider or thrips never trouble astilbe. As a border plant, astilbe is one of the best of our hardy herbaceous plants; but the feathery plume obtained in the greenhouse is much shorter, more compact, and lacks the pure whiteness of the outdoor-grown specimens. (Wm. Scott.)
