B. baselloides is a rather pretty trailing plant which gives clusters of white flowers in late autumn. In a few districts it is hardy, but it ought usually to have the protection of a frame in winter, or to have its tuberous roots stored in sand until spring, when it may be planted about three inches deep. It likes a rich, but light soil.
Bravoas
Bravoa geminiflora, the only one of the three species in cultivation, is hardy in warm places in the south, but for most gardens its proper treatment is that of a frame bulb. It has beautiful orange-red, drooping flowers in July, on stems from one and a half to two feet high. It likes a light, sandy soil, and may be planted about three inches deep in autumn.
Cypellas
These are pretty plants allied to the Iris, and well suited for growing in pots in the greenhouse as well as for frame cultivation. They may also be planted out in spring, and lifted in autumn and potted. They like a light, sandy soil, and may be planted two inches deep in pots, or three inches if in a frame. In the latter it is well to give them a little covering in frosty weather. They may be raised from seeds or increased by offsets. Cypellas grow from one to three feet high. The most desirable are Herberti, yellow; peruviana, yellow, spotted red-brown; and plumbea (syn. Pohlia platensis), lead-coloured, with a tinge of yellow in the centre.
Dahlias
The Dahlia is too extensive a subject to permit of its being fully considered in the limits of this work, but, without entering upon particulars regarding the various sections and varieties of the flower, it may be helpful to give a few broad cultural details for the benefit of those who grow the flower to a limited extent. It is a plant which must have generous treatment, and to give this it is essential that the ground should be deeply prepared by digging, and thoroughly manured with well-decayed manure. The plants may be put out as soon as danger from severe frost is past, and they should be allowed plenty of room. For exhibition purposes from five to six feet apart will be found a suitable distance. The plants should be staked immediately, and covered at nights when there is a prospect of a cold night occurring. Pots filled with moss or hay may be placed on the top of the stakes and examined regularly for earwigs. When the plants begin to make growth, the soil ought to be well mulched with half-rotted manure. Watering should never be neglected, and as the plants grow they must be properly tied to the stakes. Thinning and disbudding are necessary to secure the largest possible blooms for exhibition flowers. These may also require to be shaded and protected from bad weather. When the plants are destroyed by frost in autumn, they may be cut down to within six inches of the surface of the soil, and, after leaving them in the ground for a few days, lifted and stored out of the reach of frost. Dahlias are propagated by seeds, division of the tubers, and by cuttings, the two last being the only way of propagating named varieties. Seeds are sown in pans or pots in March under glass. When the young plants can be handled, prick them out into small pots and grow under glass until large enough to plant out in the beds. Old tubers may be divided if a portion of the crown with an eye or bud is attached to each piece. These must be put into small pots and grown on for a short time. Cuttings are easily struck from February to August. In spring the old tubers are placed in heat with the crowns above the soil, and the shoots taken off when about three inches long, and struck in heat in single pots of light soil. Cuttings taken off in summer and rooted in small pots, form good "pot roots" for planting out in spring.
Galaxias
Few people grow these pretty little bulbous plants, which do well in a frame with some protection in winter, although, perhaps, even better in pots in a cool greenhouse. They bloom in May, the clusters of flowers being almost stemless. Graminea has yellow flowers, and the other species, ovata, has purple-violet blooms. They belong to the Irids. A sandy peat is the soil they prefer.
