Sophronitis in the greenhouse

Dwarf epiphytal orchids with red or violet flowers. (For cultivation see ORCirrns.) Spiraea. These are hardy plants, that are Often forced in the greenhouse for spring flowering. They should be potted in October or November in 5-or 6-ihoh pots, and kept in the cold frame until January or February when they may be brought into the greenhouse for forcing. When flower spikes begin to show apply weak stimulants in the form of liquid manure.

Remove to the cold frame again after flowering, and in June plant the roots outdoors in a sunn;y position. They should not be forced two years in suc-cession. Modern varieties include some with fine plumea of rose, pink, and white colourines.

Stephanotis. A climbing shrub with fragrant white flowers and evergreen foliage, suitable for the stove.

Pot in February or March in fibrous loam or peat, with leaf-mould, well decayed manure and coarse sand added. Prune moderately in February and water copiously during the summer. Liquid manure may be given once a week between May and September. Propagate by cuttings in spring.

Tacsonia. Greenhouse evergreen climbers with red flowers.

Pot in February or March in pots of fibrous loam or peat with some silver sand. They can be grown in well-drained tubs, pots or beds, in a sunny position, with the shoots trained up the rafters or walls of the greenhouse. Prune in February. Propagate by cuttings.

Tecoma. This is often called Trumpet Jasmine and is a very ornamental flowering, climbing shrub for the greenhouse.

Plant in winter in a soil of two parts loam and one part peat and silver sand. Prune in February. Propagate by cuttings or by layering shoots. The temperature needed for these plants depends on the species, as some of them are almost hardy, while some require the stove for cultivation. The flowers are chiefly red or orange.

For the greenhouse, pot up the bulbs in autumn or spring in fibrous loam, leaf-mould and sand, and grow in a light sunny greenhouse or window. Repot established plants every three or foul years in summer.

Water moderately in winter, freely in spring, and keep the plants nearly dry from July to September. Propagate by offsets removed at potting time.
