Primula Denticulata
Toothed Primula; Nat. Ord. Primulaceæ.
This is one of that section of the Primrose family having stout scapes and compact heads of bloom. It is a comparatively recent introduction from the Himalayas, a true alpine, and perfectly hardy in this climate. As a garden flower, it has much merit, blooming early and profusely. It cannot be too highly commended for its fine form as a plant and beauty as a flower, more especially as seen on rockwork. The flower buds begin in very early spring to rise on their straight round stems, new foliage being developed at the same time.
The flowers are arranged in dense round clusters, and are often in their finest form when nearly a foot high. They are of a light purple colour, each flower ½in. across, corolla prettily cupped, segments two-lobed, greenish white at bases, tube long and cylindrical, calyx about half length of tube, teeth rather long and of a dark brown colour. The scape is somewhat dark-coloured, especially near the apex. The leaves are arranged in rosette form, are lance-shaped, rolled back at the edges and toothed, also wrinkled and downy; they continue to grow long after the flowers have faded.
Delicate as the flowers seem, they stand the roughest storms without much hurt.
P. d. major is a larger form in all its parts.
P. d. nana is more dwarfed than the type.
P. d. amabilis is a truly lovely form, having darker foliage and rosy buds; its habit, too, is even more neat and upright, and the blooming period earlier by about two weeks.
A moist position and vegetable mould suit it best, according to my experience, and the dips of rockwork are just the places for it, not exactly in the bottom, for the following reason: The large crowns are liable to rot from wet standing in them, and if the plants are set in a slope it greatly helps to clear the crowns of stagnant moisture. Propagation is by means of offsets, which should be taken during the growing season, so that they may form good roots and become established before winter.
Flowering period, March to May.
