Nat. Ord. Saxifragaceæ.
This belongs to the encrusted section, being most distinctly toothed; from this it takes its name; the teeth are large for such small leaves. Specimens of this Saxifrage, though small, are exceedingly pretty. Excepting when there is fog or rain, it is nearly white; and the rosettes, of various sizes, from ¼in. to 1in. across, are not only neat in themselves, but are densely and pleasingly arranged in a hard flat mass. It is never more beautiful, not even in May and June, when it flowers, than in November, when the growth is both complete and ripened, and the scaly substance which is spread over the leaves and the silvery teeth combine to render it attractive.
The flowers are of the usual form, and are produced on stems 4in. to 6in. high; they are white. The leaves seldom exceed ½in. in length and 1/8in. in width; they are spathulate in form, stout, and rigid. The rosettes are somewhat flattened and numerous, and give the idea of greenish-white flowers.
S. p. hybrida is a variety of the foregoing species, and without pretending to say what the type has been crossed with to produce this handsome form, I may, for the purpose of conveying an idea of what it is like, say that it approaches S. aizoon, which also flowers in May and June. In all its parts it is larger than the type; the leaves are greener and more strap-shaped, and are more erect, but not so rigid; the habit, too, differs—it forms more rounded tufts. In all these respects it will be seen to resemble S. aizoon. It is a lovely form; the sparkling teeth are relieved by the fine dark green ground of the foliage.
These comb-leaved Saxifrages belong to the more neat and effective rock plants; the type, at least, is of alpine origin, and under cultivation it seems most happy amongst the stones. I have grown these kinds as pot specimens, on nearly flat beds, and as edging plants; and in every position they prove attractive. It is very strange that such pretty forms are not more generally seen in gardens; they will grow well on walls and the tops of outhouses, and are good subjects for town gardens. Any kind of sandy soil will do for them; that of a vegetable character is, however, the best; they may be planted with choicer things, for, unlike many of the genus, they are not rampant growers. Practically, they need no propagating; for as the specimens spread they make new roots, and at any time one or half a dozen rosettes may be slipped off for planting elsewhere. It is better, though, to avoid this with small plants, as their full beauty is not realised until they become of considerable size.
Flowering period, May and June.
Saxifraga Peltata.
Nat. Ord. Saxifragaceæ.
A new species to English gardens, hardy, herbaceous, and perennial, imported from North America; it is a truly noble plant. The illustration (Fig. 90) will convey some idea of its fine form, but the reader must rely on the description for its size when fully developed. When the flowers of this Saxifrage are in their best form, the noble foliage is scarcely half developed; a drawing, therefore (though it could hardly be made at a stage when the plant is more interesting), must necessarily fail, in this case, to give any more than an approximate idea of the parts undeveloped. Not only is this the largest species of the extensive genus at present grown in this country, but its form is both distinct and noble.
