HARDY EXOTIC FLOWERING PLANTS. 143 
(Gentianella) would grow as freely in moist places on any of our own 
mountains as it does on its native hills; as, indeed, it would in all 
moist loams, where it could not be choked by coarse and taller subjects. 
The tall willow Gentian (G. asclepiadea) is a handsome plant, which, in 
the mountain woods of Switzerland, may be seen blooming among long 
grass in shade of trees, and this fact is suggestive as to its use in this 
country. 
Snowdrops, Galanthus.—The charms of our own. Snowdrop 
when naturalised in the grass are well known to all, but many of the 
new kinds have claims also in that respect, such as Elwesi and G. 
plicatus. It is surprising how comparatively few people take 
advantage of the facility with which the Snowdrop grows in grass, so 
as to have it in pretty groups and colonies by grass-walks or drives. 
The accompanying illustration, which shows it on the margin of a 
streamlet in a Somersetshire valley, shows that it is not particular as to 
situation. It suggests the many places it may adorn other than the 
garden’ border. 
Cow Parsnips, Heraclewm.—Giant herbaceous plants, mostly 
from Northern Asia, with huge divided leaves, and umbels (sometimes 
a foot across) of white or whitish flowers. They are very suitable for 
rough places on the banks of rivers or artificial water, islands, or in 
any position in which a very vigorous and bold type of foliage may be 
desired. In arranging them it should be borne in mind that their 
foliage dies down and disappears in the end of summer. When 
established they sow themselves, so that seedling plants in abundance 
may be picked up around them. In all cases it is important that their 
seed should be sown immediately after being gathered. But it is also 
important not to allow them to monopolise the ground, as then they 
become objectionable. To this end it may, in certain positions, be 
desirable to prevent them seeding. 
Day Lily, Hemerocailis.—Vigorous plants of the lily order, with 
long leaves and graceful habit, and large and showy red-orange or 
yellow flowers, sometimes scented as delicately as the primrose. There 
are two types, one large and strong like flava and fulva, the other short 
and somewhat fragile like graminea, The larger kinds are superb 
plants for naturalisation, growing in any soil, and taking care of them- 
selves among coarse herbaceous plants or brambles. 
Christmas Rose, Helleborus.—Stout but dwarf perennials, with 
showy blooms appearing in winter and spring when flowers are rare, 
and with handsome leathery and glossy leaves. They thrive in almost
