HARDY PLANTS. 
233 
Carrot order (Umbelliferae). Seeds should be sown in light 
soil in heat in March, and the seedlings afterwards trans- 
planted, and hardened off early in May, planting them in their 
flowering positions in June. A light rich soil and a sunny 
position must be provided. 
Tradescantia (Spiderwort). — Handsome and showy 
hardy herbaceous perennials, natives of America, and members 
of the Nat. Ord. Commelinaceae. The only species worth 
growing is T. virginiana. This grows about a foot or so 
high, and bears violet-blue flowers with yellow anthers in late 
spring. Alba grandiflora, white; azurea fl. pi., double, blue; 
delicata, blush-pink ; flore pleno, double, purple ; pallida, pale 
purple; rubra, carmine; and rubra fl. pi., double, carmine, 
are pretty varieties of it. All will thrive in ordinary soil in 
partially shady borders and flower freely in spring. May be 
planted in autumn or spring. Good town or suburban garden 
plants. Increased by division in spring. 
Tricyrtis (Toad Lily). — T. hirta is a charming hardy 
perennial from Japan, belonging to the Lily order (Liliaceae). 
It bears curious orchid flowers in the axils of its leaves in 
autumn, the lance-shaped petals being spotted with purple or 
crimson. The plant grows about 3ft. high. Nigra is a form 
of it with velvety black blotches, which flowers a few weeks 
earlier than the species. These curious plants require to be 
grown in a bed of sandy loam and peat in a partially shady 
warm position. Plant in spring, and increase by division 
at the same season. 
Trientalis (Star-flower). — A genus of hardy perennials, 
with stems 3 to 6in. high, surmounted by a tuft or whorl of 
leaves, from the centre of which rise starry white flowers on 
slender stalks. T. europaea, the species here referred to, is 
a native of Britain and Arctic Europe, and grows in shady 
woods. It belongs to the Primrose order (Primulaceae), and 
flowers in June and July. A shady border, or a bed of peat or 
bog-loving plants, is the best place for it. It also does well 
on partially shady rockeries. Plant in spring and increase by 
division of its creeping root-stocks in early spring. 
Trifolium (Trefoil; Clover). — Very few species of this 
genus are worthy of a place in the flower garden. The only 
one we can recommend is T. repens purpureum. This has 
a broad purple spot on the under sides of each leaflet and 
small white, fragrant flowers borne in summer. It is often 
called the Four-leaved Shamrock. A suitable plant for clothing 
bare spots on dry banks or borders. Plant in autumn. In- 
creased by division. Nat. Ord. Leguminosae (Pea family).
