Half-shaded places are preferable for these easily cultivated plants. Very dry grounds should be avoided, from the fact that they are best in swampy places. In the ordinary border they should have a very liberal mulch of old manure in their growing season: 4-5 in. thick is none too much: the surface roots will feed in this compost, and the plants are not so liable to suffer from drought when thus protected.
