THE FLOWER GARDEN. 
species ; C. grandiflora, bright orange-yellow, summer, 3ft. ; 
C. verticillata, yellow, autumn, 2ft. ; lanceolata, yellow, summer, 
3ft. ; C. rosea, pale rose, July and August, ift. Grown in 
masses in sunny borders in not too heavy a soil, these plants 
will make a brilliant display of colour, while their handsome 
flowers, borne on long stalks, will also be found most useful 
for cutting. C. grandiflora is, unfortunately, liable to die in 
damp or severe winters, but this difficulty may be easily got 
over by raising plants from seed in gentle heat in March, 
transplanting the seedlings outdoors in May, and planting 
them in their flowering quarters the following September to 
flower the next season. All the perennials may be planted in 
autumn or spring. The latter may be increased by seeds sown 
as advised for C. grandiflora, or in the open border in April ; 
also by cuttings in a cold frame in autumn ; division of the 
plants in spring. 
Coris. — The only species of this genus is C. monspeli- 
ensis, a dwarf, branching plant, about 6in. high, belonging 
to the Primrose order (Primulacese). It has lilac or rosy- 
purple flowers borne in summer, and thyme-like foliage. 
Strictly speaking, it is a perennial, but it does best treated as 
a biennial — that is, reared from seed sown in sandy soil in a 
cold frame in autumn or spring, the seedlings being afterwards 
transplanted into boxes or small pots and planted out later, in 
spring or summer. 
CorydaliS (Fumitory). — Hardy perennials, members erf 
the Nat. Ord. Fumariaceae, and adapted for growing on 
rockeries or old walls. C. bulbosa is a tuberous-rooted kind, 
4 to 6in. high, bearing purplish flowers in April. Is suitable 
for massing on the _margins of borders, or for naturalising in 
woodland gardens. C. lutea (Yellow Fumitory) has pretty 
green foliage and yellow flowers borne freely in summer. It 
grows about ift. high, and is specially adapted for massing 
on the margins of borders or growing in the chinks of old 
walls. C. nobilis (Noble Fumitory) is a Siberian species, with 
yellow flowers borne in May ; height 9in. Suitable for border 
culture or rockeries. C. thalictrifolia, yellow, flowers in May, 
but is only hardy in the south. All will thrive in ordinary 
soil in sun or shade. Plant in spring. Increased by seeds 
sown outdoors in April, or by division of the roots in March. 
Cosmidium. — C. burridgeanum is a hybrid between 
two annuals — Thelesperma filifolium and Coreopsis tinctoria 
— and hence belongs to the same order (Composite). It is a 
hardy annual, grows i8in. high, and bears deep crimson-purple 
flowers in summer. Sow seeds where required to grow in 
ordinary soil in a sunny border in April.
