HARDY EXOTIC FLOWERING PLANTS. 151 
Water Lily, Nymphaea and Nuphar-—Two noble North Ameri- 
can plants well deserve naturalisation in our waters, associated with 
our own beautiful white and yellow water lilies—the large Nuphar 
advena, which thrusts its great leaves well out of the water in many 
parts of North America, and the sweet-scented Nymphea odorata, which 
floats in crowds on many of the pine-bordered lakes and lakelets of 
New England, to a non-botanical observer seeming very like our own 
water lily. 
Daffodil, Narcissus.—Most people have seen the common daffodil 
in a semi-wild state in our woods and copses. Apart from varieties, 
there are more than a score distinct species of daffodil that could be 
naturalised quite as easily as this in all parts of these islands. We 
need hardly suggest how charming these would be, flowering in early 
spring and summer in the rougher parts of pleasure grounds, or along 
wood-walks, or any like position. 
Bitter Vetch, Orobus.— Banks, grassy unmown margins of 
wood-walks, rocks, fringes of shrubberies, and like places, with 
deep and sandy loam, well drained, will grow the beautiful spring 
Bitter Vetch or any of its varieties or allies perfectly. 
Evening Primrose, Hnothera.—Among the largest-flowered and 
handsomest of all known types of herbaceous vegetation. The yellow 
species, and varieties like and allied to the common Evening Primrose 
(da. biennis), may be readily naturalised in any position, from a rubbish- 
heap to a nice, open, sunny copse; while such prostrate ones as 
CE. marginata and CE. macrocarpa will prove very fine among dwarf herbs 
on banks or in open sunny places, in light or calcareous soil, These 
noble and delicately-scented flowers are very easily grown and very 
beautiful in any position, They, however, from their height and bold- 
ness, and the freedom with which they grow in almost any soil, are 
peculiarly suited for the wild garden, for shrubberies, copses, and the 
like, sowing themselves freely. 
Cotton Thistle, Onopordon.—Large thistles, with very handsome 
hoary and silvery leaves, and purplish flowers on fiercely-armed stems. 
No plants are more noble in port than these, and they thrive freely in 
rough open places, rubbish-heaps, etc., and usually come up freely from 
self-sown seeds. 
Star of Bethlehem, Ornithogalwm—Various handsome hardy 
species of this genus will thrive as well as the common Star of Bethle- 
hem in any sunny, grassy places. 
Creeping Forget-me-not, Omphalodes.—The creeping Forget-
