This new floral visitor, condemned by some as an outdoor plant, is yet most highly recommended by D. T. Fish, in The Garden, as fit to take high rank as a pot plant. It bears moderate forcing remarkably well. The leaves are, if possible, greener and more deli-! cately serrated and prettily arched when grown under glass. The flower steins rise higher, and the whorls of flowers unfold with more confidence, greater freedom, and to a wider measure. Grown near the glass, their color suffers but little; it, however, hardly reaches to the brilliancy and depth of hue to which it attains in the open air. It is, however, exquisitely beautiful, and any loss of depth of tone in the flowers is compensated for by the greater size and more delicate beauty of the leaves. In size, and also in beauty of leaf, it is unmatched among primroses. It fits in nicely with most other flowers, 'adding richness and variety to the best of them. The color - that of the deepest pink - is one that is rather scarce; and the habit of the plant, and its bold flower-stems, give it a distinguished air, even among the choicest species under glass. Single plants are effective, but a row on a shelf forms a feature in the greenhouse or conservatory at once unique and rich.
It is also admirably suited for vases, window sills, landings or staircases. Among the choicest contrasts I have seen for many a day, was a double row in a long passage of the old Saxifraga pyra-midalis, and the Japanese Primrose. The plants presented the most complete contrast to each other; and in the contrast, from the distinctive simple beauty of each, there resulted a most satisfactory effect.
This old Saxifrage is one of the most effective of pot plants. Last year it was associated with blue Lobelias, depending from brackets above, and drooping from the base of the shelf below; and the result was even more beautiful. The two plants, While contrasting exquisitely in color, harmonized well in grace and delicacy of flowers and habit. The Lobelia threw out streams of blue upon and from the white; the Primula japonica sent a line of the most brilliant pink right through the substance and along the side of the snowy and fluffy Saxifrage.
