Part 43

Swan River Daisy.--See "Brachycome."

Sweet Alyssum.--See "Alyssum."

Sweet Flag.--See "Acorus."

Sweet Peas.--See "Peas, Sweet."

Sweet Rocket.--See "Rocket."

Sweet Scabious.--See "Scabious."

Sweet Sultan.--Sweet-scented, Thistle-shaped hardy annual flowers, which are very useful for cutting. They may be raised in any garden soil from seed sown in March or April, and will flower in August. Height, 1-1/2 ft.

Sweet William.--Well-known hardy perennials, and deservedly favourite border plants, which may be grown in any good soil; but to have them to perfection they should be placed in light, loamy ground mixed with a little old manure and sand. They can be raised with little trouble from seed sown thinly at any time between March and midsummer where they are to bloom, and may also be increased by dividing the old plants in spring. They produce their flowers in July. Height, 1-1/2 ft.

Symphoricarpus (Snowberry).--A handsome species of St. Peter's Wort. The shrubs will grow in any ordinary soil, are hardy, and readily propagated by suckers, which are produced abundantly; or cuttings may be taken either in spring or autumn. They bloom in August. Height, 4 ft.

Symphytum Caucasicum.--Hardy perennials. They will grow in any soil or situation, even thriving under the shade of trees, and may be increased by division. June is the month in which they flower. Height, 3 ft.

Syringa (Lilac.)--There are many choice varieties of these favourite shrubs, but any of them may be grown in a tolerably good soil. They are propagated by layers or by suckers from the root. They bloom in May or June. Height varies from 4 ft. to 12 ft.

Tacsonia.--A beautiful twining shrub belonging to the Passiflora family. It should be provided with a rich soil, and, as the flowers are produced upon the lateral shoots, it requires frequent stopping. Syringe frequently in warm weather to induce a quick growth. It is a quick grower, and, when properly treated, a profuse bloomer, the flowers being produced in July, August, and September. Cuttings of young shoots placed under glass in a sandy soil will strike. Height, 20 ft.

Tagetes (French and African Marigolds).--Half-hardy annuals, very elegant when in flower, and deserve a place in the garden. The seed should be sown on a hotbed in March or April, the plants gradually hardened off, and placed in the open at the end of May in a rich, light soil, when they will flower in August. Height, 1 ft. to 2-1/2 ft.

Tamarix.--Neat feathery plants, very suitable for banks and thriving at the seaside, as is evidenced by its luxuriant growth along the parades at Eastbourne. The hardy kinds will grow in any soil, and may be propagated by cuttings planted in the open either in spring or autumn. The greenhouse and stove varieties require a soil of loam and peat. Cuttings of these should be placed in sand under glass. They flower in June and July. Height, 8 ft. to 10 ft.

Tansy.--A feathery-foliaged hardy perennial, useful for mixing with cut blooms. No special treatment is required. Height, 11 ft.

Taxus.--See "Yew."

Tecoma.--Ornamental evergreen shrubs of a twining nature, needing a greenhouse for their cultivation. They require a rich, loamy soil mixed with a little sand, or loam and peat, and rejoice in shade and moisture. T. Radicans will grow in the open against a wall, but a warm situation is needed to make it flower. They may be propagated by cuttings of the roots placed in sand under a hand-glass, and by layers. Their flowers are produced in July and August. Height, 6 ft. to 30 ft.

Telekia.--See "Buphthalmum."

Tellima Grandiflora.--A hardy and very ornamental perennial with round bronzy foliage and spikes of white flowers at midsummer. It succeeds best in peat, but will grow in any rich, light soil. To increase it, divide the roots. Height, 1 ft.

Tetratheca.--Pretty greenhouse evergreen shrubs which produce pink flowers in July. They flourish in a soil consisting of equal proportions of loam, peat, and sand. Cuttings of the young wood planted under glass in a sandy soil will strike. Height, 1 ft.

Teucrium Scorodonia.--This hardy herbaceous plant will grow in any ordinary garden soil. It flowers in July, and is easily raised from seed or increased by division. Height, 1-1/2 ft.

Thalictrum.--Hardy Fern-like perennials, suitable for the backs of borders. They grow well in any light soil from seed sown in spring or autumn, and may also be increased by division.

Thermopsis Montana(Fabacea).--This hardy perennial produces spikes of yellow Lupin-like flowers from June to September. The soil should be light and rich. As the plants suffer by division, it is best to raise them by seed, which may be sown either in autumn or spring. Height, 2 ft.

Thladianthe Dubia.--A fine climbing plant with handsome foliage and an abundance of fine yellow flowers. Quite hardy. Sow on a hotbed early in spring, and when sufficiently large and strong, pot off, place in a cold frame to harden, and plant out at the end of May in rich soil.

Thrift.--See "Armeria."

Thumbergia.--These slender, rapid-growing climbers are extremely pretty when in bloom during June, but they are only half-hardy; they therefore need greenhouse care, or to be planted in a warm situation. They flourish best in a mixture of sandy loam and leaf-mould, and may be grown from seed sown in heat (65 to 75 degrees) early in spring. Cuttings strike readily. Height, 4 ft.

Thuya (Arbor Vitae).--Very decorative conifers, mostly of conical shape, and indispensable to the shrubbery. They thrive in any soil, but prefer a moist situation. For sheltered positions, where a small dome-shaped bush is required, the Chinese Arbor Vitae (Biota Orientalis) is most desirable; it delights in a heavy soil. The Biota Elegantissima is one of the most unique hardy shrubs cultivated, and presents a bright golden appearance. Another effective yellow variety is the Semperaurescens, which retains its colour throughout the winter, and makes a fine pot-plant. One of the most beautiful of all evergreens is the Thuyopsis Dolabrata; its flat, spray-like leaves are bright green above and silvery below. The China varieties are somewhat tender, and require protection from frost. They may all be propagated from seed or by cuttings.

Thymus.--Effective little perennials for rock-work, growing best in a light, dry, sandy soil. The hardy kinds like an exposed position; rarer kinds should be grown in pots, as they need protection in winter. They are easily increased by seed sown in spring, by cuttings or division. Height, 3 in. to 6 in.
