Tradescantia Virginica (_Spider Wort_).--A hardy herbaceous plant. In
a light, rich soil it will flower in July. Height, 1 ft. There are
other varieties of Tradescantia; they all make good border plants,
thrive in any situation, and are continuous bloomers.
Transplanting.--Plants may be transplanted as soon as they are large
enough to handle. They must be lifted carefully with a small trowel,
or if they are very small, such as Golden Feather, with a still
smaller blunt article, disturbing the roots as little as possible. It
should be done when the ground is wet, and preferably in the evening.
In dry weather they should be well watered twelve hours before they
are disturbed. Shade them from sun for one or two days. Cabbages,
Lettuces, Cauliflowers, Broccoli, Kale, and other members of the
Brassica family _must_ be transplanted, or they will be a failure.
Root crops such as Carrots, Parsnips, Turnips, etc., must not be
transplanted, but thinned out. Celery may be transplanted in June or
July.
Traveller's Joy (_Clematis Viorna_).--This hardy climbing plant grows
best in a light soil, flowers in August, and is increased by layers of
the young shoots in summer. Height, 12 ft.
Trees, Plants that Flourish under.--Ivy, St. John's Wort (Hypericum
Calycinum), early-flowering White Aconite.
Tricyrtis.--These greenhouse herbaceous plants bloom in May. A rich,
light soil suits them. Height, 6 in.
Trientalis Europæa (_Star Flower_).--To grow this native perennial
to advantage, it should be planted in leaf-mould with which a large
proportion of sand has been mixed. Confine the roots to a narrow
compass by means of slates placed just beneath the surface of the
soil. Let the ground be kept moist, but well drained. The bloom is
produced during May and June, and it is propagated by runners. Height,
6 in. to 8 in.
Trifolium Repens Pentaphyllum.--A showy, hardy, deciduous perennial.
It thrives in ordinary soil, puts forth its white flowers in June, and
is propagated by seed or division. Height, 6 in.
Trillium Erectum (_Wood Lily_).--This tuberous perennial is quite
hardy, and flourishes in partial shade. The soil must be light and
rich, yet moist. The plant does not increase very fast, but the roots
of good-sized plants may be divided. It flowers in May and June.
Height, 6 in.
Tritelia.--A charming spring-flowering plant, bearing pretty white
star-like flowers on slender stalks. It is used largely for edgings.
It looks well in clumps on the front of borders. Plant in autumn, and
divide the bulbs every two or three years. Height, 6 in.
Tritoma (_Red-hot Poker, or Torch Lily_).--Requires a rich, sandy
soil, and to be protected in a frame from wet and frost in the winter.
Increase by division or by suckers from the root. The flower spikes
grow 18 to 27 in. long. The crown of the plant should not be more than
11/2 in. in the soil, which should be dug deeply and mixed with rotted
manure. In winter, if it is left in the ground, surround the plant
with 2 in. of sawdust, well trodden. Remove this in May, and water
liberally with liquid manure till it blooms. The best time to plant is
March or October. By many it is considered advisable not to disturb
the plant too often.
Tritonias.--These somewhat resemble miniature Gladioli, and are
among the most useful bulbs for pot-culture. Plant from September
to December, placing five or six bulbs in a 5-in. pot, and using a
compost of loam, leaf-mould, and silver sand. Plunge the pots in ashes
in a cold pit or frame, and keep them dry until the plants appear.
When in full growth they may be removed to the conservatory, placing
them near the glass, and giving careful attention to watering. For
outdoor cultivation choose a sunny, sheltered position, with a light,
rich, sandy soil. Give protection in frosty weather by covering with
dry litter.
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.
