The annual catchfly is Silene pendula which grows to about 6 in. with clusters of light pink flowers in summer. It should be given a sunny position and thinned to 6 in. There are several attractive rockery species which only demand light, well-drained soil (they dislike winter wet). Easily increased by division in spring. Silene acaulis is only I in. tall with stemless, rose pink flowers in early summer. In some gardens it does not bloom freely. The white form is rare. S. alpestris makes low, spreading tufts of narrow, glossy leaves and bears numerous white, fringed flowers in summer. Height about 4 in. There are double and single forms.
