Part 29 (1/2)

Trollius Altaiense (_Globe Flower_).--A pretty, hardy herbaceous plant, with very handsome foliage. It likes a light but moist soil, may be increased by seed or by dividing the root, and flowers in May.

Height, 9 in. to 2 ft.

Trollius Asiaticus.--A very pretty herbaceous plant, suitable for the border. It may be raised from seed sown in the autumn, and grown on in light, moist soil. The plant is hardy and flowers in May. Height, 1 ft.

Tropaeolums--

_JARRATTI_ (_scarlet, orange, and black_) are remarkable for a slender and graceful growth. Well adapted for covering wire globes, trellises, etc.

_LOBBIANUM_ (_various colours_).--Elegant dwarf climbers, suitable either for the conservatory or for outdoor culture. They may also be used for bedding if planted thinly and kept pegged down; or may be grown in window-boxes. Height, 6 ft.

_PENTAPHYLLUM_ (_red_) is slender and graceful, and an elegant climber.

_POLYPHYLLUM_ (_yellow_) succeeds best against a south wall. It is hardy, has rich abundant glaucous foliage, and is a particularly fine climber.

_SPECIOSUM_ (_scarlet_).--Of wild, graceful, luxuriant and slender growth. Fine for covering walls and fences, festooning arches, etc.

Plant at the beginning of October in an eastern aspect or at the base of a north wall, the soil and atmosphere being moderately moist. Bury the roots 4 in. deep.

_TUBEROSUM_ (_yellow and red_) is quite hardy, and may be planted in any situation.

Generally a light, rich soil is most suitable. The greenhouse varieties may be increased by cuttings placed in sandy soil under gla.s.s. The tuberous-rooted kinds should be taken up in winter and kept in sand till spring, when they may be planted in a sheltered part of the garden. The annuals merely require to be sown in the open in spring. They flower in July, August, and September. Height, 1 ft. to 10 ft. (_See also_ ”Canary Creeper.”)

Trumpet Flower.--_See_ ”Bignonia.”

Tuberose.--Plant the bulbs in January in a mixture of sandy loam and rotten dung, or leaf-mould, using a small pot for each bulb. Plunge them in a hotbed, taking care that the temperature does not fall below 60 degrees, and withhold water until the foliage appears, when a moderate amount should be given. When the pots are full of roots, s.h.i.+ft the plants into larger ones, and grow on in a house with a uniform high temperature and moist atmosphere. For a succession of bloom place the roots in a cold frame and cover with cocoanut fibre until growth begins, then remove the fibre, water moderately, and transfer the most forward plants to the conservatory. Bloom may be had all the year round by planting in succession from September to June.

Tulips.--Drainage may be considered as the chief means of success in the cultivation of these showy spring flowers. The soil they like best is well-rotted turf cut from pasture land and mixed with a moderate amount of sand, but they will thrive in any ground that is well drained. The bulbs should be planted during October and November about 3 in. deep and 5 in. apart, either in lines or groups, and they retain their bloom longest in a shady situation. As soon as the leaves begin to decay the bulbs may be taken up, dried, and stored away, keeping the colours separate. For pot-culture the single varieties are best.

Put three bulbs in a 5-in. pot and six in a 6-in. one, and treat in the same manner as the Hyacinth. They may, if desired, be forced as soon as the shoots appear. When required to fill vases, etc., it is a good plan to grow them in shallow boxes, and transfer them when in flower to the vases or baskets. By this method exact.i.tude of height and colouring is ensured. Tulips are divided into three cla.s.ses: (1) Roses, which have a white ground, with crimson, pink, or scarlet marks; (2) Byblomens, having also a white ground, but with lilac, purple, or black marks; and (3) Bizarres, with a yellow ground having marks of any colour.

Tunica.--Same treatment as ”Dianthus.”

Turkey's Beard.--_See_ ”Xerophyllum.”

Turnips.--To obtain mild and delicately-flavoured Turnips a somewhat light, sandy, but deep, rich soil is necessary. For a first crop sow the Early White Dutch variety in February or the beginning of March on a warm border. For succession sow Early s...o...b..ll at intervals of three weeks until the middle of July. For winter use sow Golden Ball, or other yellow-fleshed kinds, early in August. Thin each sowing out so that the bulbs stand 9 in. apart. To ensure sound, crisp, fleshy roots they require to be grown quickly, therefore moist soil and liberal manuring is necessary, and the ground kept free from weeds. If fly becomes troublesome, dust the plants with quicklime early in the day, while the dew is on them, and repeat the operation as often as is necessary.

Tussilago Fragrans (_Winter Heliotrope_).--A very fragrant hardy perennial, flowering in January and February. It will grow in any good garden soil and bears division. Height, 1 ft.

Twin Flower.--_See_ ”Bravoa.”

U

Ulex Europaeus Flore Pleno (_Double Furze_).--This elegant, hardy, evergreen shrub likes a rich, sandy soil, and may be increased by cuttings planted in a shady border and covered with a hand-gla.s.s.

Height, 5 ft.

Umbilicus Chrysanthus.--This little Alpine plant should occupy a warm, sheltered, and dry situation, and be protected with an overhead screen in wet seasons. The soil it most enjoys is a mixture of peat and coa.r.s.e sand. Its proc.u.mbent stalks emit roots. This new growth may be transplanted in the spring or early summer months. Height, 6 in.

Uvularia.--Beautiful hardy perennials, producing drooping flowers from May to July. They succeed best in a light, sandy soil, and may be increased by dividing the roots. Height, 1 ft.
