Although we have already and recently called attention to succulent plants, and to beds composed of them, as a most interesting and desirable feature to add to decorative gardening, we feel anxious still further to recommend them to the notice of those of our readers who may not yet have devoted their attention to so interesting a class of plants. In February we gave illustrations of some very effective Sempervivums, etc. Our figures in this instance are taken from, photographs of two very attractive and to some extent representative plants. Sem-pervivum canariense is a very pleasing plant. Its leaves are very beautifully arranged, and are of a soft pea-green, covered over with a very fine downy hair, and terminating in an abrupt nipple-looking point. Altogether the plant has a soft and pleasing appearance, and contrasts well with the polished bright bronzy-looking foliage of Sempervivum urbicum. The leaves of the latter assume a chestnut colour in summer when exposed to full sun, and they are beautifully and very finely toothed in the same way as the Pine-Apple leaf, but much more finely and densely set with a fringe of minute teeth.
These are two plants which should be in every collection.
