The Garden Under Glass

THE BEST FLOWERING PLANTS 69 plant has, until recent years, been known as a genista, but botanical autliorities assure us that cytisus is more correct. Except for there being sometimes a difficulty in propaga-tion by cuttings, the cytisus cannot be said to be a fastidi-ous subjeet, and is nearly hardy. Cuttings may be inserted in the usual way in spring and should be carefully attended to in the matter of water until roots are emitted, when the young plantlets may be potted singly into 2-inch pots, to be eventually transferred into larger ones. The cytisus may be grown as a standard, a pyramid or a bush. The bush is the general and most convenient form, while the pyramid is now rarely found. A light position in a cool house will suit the young plants well, for they resent heat. A few pinchings will make them shapely bushes and feeding well with liquid manure will make them floriferous plants. After flowering, the growth should be cut back into shape and the plants stood outside till the autumn. Frequent potting for established plants is not needed ; an overhauling every second or third year will suffice. Each year work on a few young plants and destroy a few oid ones. In this policy lies progress. The coronilla is more easily struck from cuttings, and, moreover, is of a hard constitution. It is a negligent man’s plant, for I have known it give quite reasonable results when left unpotted and unsupplied with stimulants for over five years. Neither cytisus nor coronilla are fastidious as to soil, and might well be given any general soil which happens to be on the bench. Cytisus racemosus and Coronilla glauca are the species grown in the greenhouse. Coleus Thyrsoideus Though it has not the ornamental leaves of the well-known coleus, this plant is well worth growing for the
