HARDY PLANTS.

obtain a good variety of shades of colour from a mixed packet 
of seed, and these are good enough for ordinary garden 
decoration, but if a special colour or a really good type of 
plant is required, such as for growing in beds, then named 
varieties must be resorted to. There are single and double 
named varieties. The best doubles are Hermione Grasshoff, 
orange-scarlet ; and granSiflorum plenissimum, yellow, with 
a maroon blotch on each petal. These can only be perpetuated 
by cuttings in heat in spring or summer. The single varieties 
that are specially suited for bedding, because of their compact 
dwarf habit, are Mrs. Clibran, yellow ; Bedfont Rival, scarlet ; 
Vesuvius, brilliant scarlet; and The Moor, maroon. These 
also require to be increased by cuttings to keep them true 
to habit and colour. Named sorts that can be reared from 
seed are Tom Thumb, scarlet; Crystal Palace Gem, yellow; 
Empress of India, crimson ; King Theodore, brownish-purple ; 
Ruby King, purplish-red ; and Terra-cotta, various pretty art 
tints of buff, etc. These come fairly true from seed. Nearly 
all seedsmen, however, have their own specially selected mixed 
strains, which yield a charming variety of colour. Seeds may 
be sown in the beds or borders in March or April where 
required to flower, the plants being afterwards thinned out in 
showery weather to 8 or min. apart. The thinnings may be 
used to fill up vacancies, or seeds may be sown in gentle heat 
in March, the seedlings grown on in boxes and planted out in 
May. Nasturtiums do best in rich soils in sunny positions, 
their vigour and duration of flowering being greater than when 
sown in poor hungry soils. They may be grown in beds in 
mixture or in lines of different colours ; as edgings to borders, 
or in bold masses in the border; or utilised in conjunction 
with the tall kinds for filling vases in summer. For climbing 
species see chapter on Climbers. 
Tunica. — There is only one species of this genus grown 
in gardens, and that is T. Saxifraga, a native of the Alps, and 
a dwarf perennial, growing 3m. high, and bearing rosy 
blossoms in loose panicles in July. It belongs to the Carna- 
tion order (Caryophyllaceae), and is suitable for growing in 
the chinks or crevices of old wells, or among small stones on a 
sunny rockery. Ordinary soil will suffice. Plant in spring. 
Increased by seeds sown in April where required to grow, or 
in cold frames in spring or autumn, the seedlings being 
planted out later on. Also by division in March. 
Tussita.g'O (Coltsfoot). — The variegated form of T. Far- 
fara, a British weed, is sometimes grown in damp shady 
borders, either as an edging or in masses among ferns and 
other shade perennials. It often does also on stonv banks.
