LIST OF PLANTS 183 
flowered U, montana and U, Endresti are propagated by 
division just before growth commences, they should be 
suspended in shallow teak Orchid baskets in fibrous peat 
and sphagnum moss in a moist stove temperature. 
VacciniuM.—Propagate by layers and seed sown in 
gentle heat in spring, hardening off before planting out 
in moist, peaty soil. 
VALLISNERIA.—This favourite submerged aquatic for 
indoor aquaria is interesting on account of the peculiar 
manner in which fertilisation is effected and the facility 
and clearness by which cyclosis can be seen when 
magnified. It is propagated by division and creep- 
ing stolons. Female plants are the most vigorous in 
growth. 
VaLLotTa (ScARBOROUGH LiLy).—Propagate in June 
and July by offsets from old bulbs, which flower best 
when seldom disturbed. Seed sown immediately after 
ripening will grow and flower in about three years. 
VEGETABLE MArrow.—Sow seed singly in small pots 
in a little warmth towards the end of April to harden off 
and plant out in June. 
VERBASCUM.—The garden sorts should be sown out- 
doors in April. 
VERBENA.—Bedding Verbenas can be raised from seed 
sown in heat in April, and by internode cuttings inserted 
in a close frame in autumn, and very rapidly in spring, 
using very sandy compost and brisk, moist heat. The 
hardy V. venosa may be increased by division of the 
roots in spring and by seed sown in March or April. 
VERONICA.—Propagate the herbaceous sorts by divi- 
sion of roots in autumn or spring; shrubby kinds by 
cuttings inserted in a cold frame in June or July and 
with a little warmth in spring.
