HARDY PLANTS.

which should be vertical. Grade the crowns into three sizes, 
large, medium and small, and plant each in a separate bed. 
Plant the crowns zin. apart against the vertical side of the 
trench, and with their points just below the surface. Fill in 
with soil ; then 6in. from this row open another drill, plant 
as before and so on, till the bed is completed. In dry weather 
give copious supplies of water, and during the growing season 
occasional applications of weak liquid manure will be bene- 
ficial. In autumn top-dress the bed with well decayed manure. 
To grow these lilies well it is advisable to lift and replant every 
third year. 
Coptis (Gold Thread). — Evergreen bog plants, belonging 
to the Buttercup-order (Ranunculaceae). They are suitable for 
growing in peaty soils in company with Heaths, Azaleas, and 
similar shrubs. The best known species is C. trifolia, a native 
of N. America and Europe, with trifoliate leaves, fine, yellow 
roots, and white flowers borne in late spring; height, 3 to 6in. 
The other species are C. asplenifolia, white, summer, 1 ft. , 
N.W. America; C. occidentalis, white, summer, California, 
6in. ; and C. orientalis, white, summer, Japan, 6in. Grow in 
moist, sandy peat on the margins of borders or on rockeries. 
Plant in autumn or spring. Increased by seeds sown in sandy 
peat in cold frames in autumn, or division of the roots in 
October or March. 
Coreopsis (Tickseed). — Hardy annuals and perennials, 
belonging to the Daisy order (Compositae), and natives of N. 
America. The annual species are often placed in another 
genus, Calliopsis, and will be found described as such in 
many trade lists. Here we include them in the genus now 
under notice. The annual kinds are very showy border plants, 
and the flowers, moreover, are most useful for cutting. Of 
these, C. atkinsoniana is a pretty kind, with yellow and brown 
flowers, height 2'ft. ; C. coronata, orange, spotted with brown, 
ift. ; C. Drummondi, orange-yellow, ift. ; C. tinctoria, yellow 
and crimson-brown, 2ft. ; C. tinctoria flore pleno, double and 
semi-double flowers, very pretty, 2ft. ; C. tinctoria marmorata, 
marbled yellow and brown, 2ft. ; C. tinctoria atrosanguinea, 
purple, 2ft. ; and C. tinctoria nigra speciosa, dark brown, 2ft. 
Seeds of the foregoing should be sown in patches in sunny 
borders in April, May and June, to provide a succession of 
flowers. If the seedlings are thinned out early to 6 or 8in. 
apart they assume a bushy growth and have a finer effect. 
Seeds may also be sown in the border in September to yield 
an early supply of flowers the following season. Ordinary 
soil. The perennial species include : C. auriculata, yellow, 
borne on long stalks late in summer, 2ft., a hardy, free-growing
