HELIOTROPE.
The new Heliotrope Le Negre is the darkest of this genus, and Snow Wreath the nearest approach to white we have yet had; truss very large, growth compact, and fragrance exquisite. Garibaldi is almost white; Mrs. Burgess is dark violet, and Duc de Lavendury is a rich blue, dark eye.
Sweet Alyssum is another of the essential flowers for the border, admirable for edgings, for its dwarf habit and continuity of bloom. The great novelty of last year was the new double variegated Sweet Alyssum—"The Gem." The flowers are very full, and the foliage broad with a mid-rib of light green, bordered on each side with pure white. It is a fine, compact grower, and far superior to anything of this species yet offered.
Lantanas, I think, add greatly to the attractions of the garden, so rich in color and profuse in blooming. Clotilda, pink with yellow center, and Comtesse de Diencourt, flower bright rose and yellow center sulphur, are very desirable. Alba perfecta, pure white, is fine, so also is Alba lutea grandiflora, white with yellow center. Mine d'Or is a new variety, with bright orange and crimson flowers, and golden variegated foliage. M. Schmidt is a beautiful novelty. Flowers of a brilliant yellow, passing into purple vermilion; grows in the style of a Petunia.
NEXT to Primroses, and by no means below them in value, we place the Cyclamen. The leaves, a deep green with white embroidery, are very ornamental, but when surmounted with a wealth of bloom, what can be more charming? Two of mine have begun to blossom—a white and a pink—and the buds are numerous. Others will bloom later. They continue in bloom for a long period, and are easy of culture, though where there is over-dryness of atmosphere, they are apt to be infested with the red spider. They need to be frequently sprayed and it is well to immerse occasionally the entire plant in water so as to wet the under surface of the leaves. The water ought to be tepid, and indeed for all plants in cold weather. To keep the dirt from falling out when the plant is plunged top downward, something can be wrapped around the pot. A mixture of turfy loam and sandy peat is best, but when not available, leaf mold or a rich mellow soil mixed with silver sand will do.
There are several varieties of Cyclamen, but the most common is persicum, and many catalogues name no other. One of mine is gigantium, an improvement on persicum, the flowers being much larger and finer in every respect. Among many catalogues I find this named in only one. Persicum, white and pink, is a sweet scented variety from Cyprus; Africanum, white and rose, from Africa; hederæfolium, from Britain. Other rare and expensive sorts are Atkinsii, white, crimson and rose colored; Europeum, red, and Coum, which in the early spring months bears above its very ornamental leaves "a profusion of small bright, rosy, crimson and snow-white turbinate blossoms of a roundish recurved outline, blotched with violet-crimson at the base, very beautiful."
The bulbs of all Cyclamens, except Coum, should be placed on the surface of the soil, covered half an inch, and water given moderately till the leaves are fully developed, and the flowers appear, when it may be applied more liberally. Do not make a mistake and plant your bulb upside down as did a lady I know of. "I have an idea that it is put in wrong, as the leaves seem to come from the under side," she writes. It is difficult to tell sometimes which is the right side to put down.
Persicum, with its dappled green and silvery gray, rounded, heart-shaped leaves, embroidered margins, is a fine ornament, but when these are surmounted with a profusion of pure silvery white oblong lanceolate petals, blotched with violet-crimson at their base, borne on slender flower-scopes, the plant is very beautiful. It varies in color from snow-white delicate peach and rosy crimson. Some are delightfully fragrant. During the growing and flowering season the plant should have a full exposure to the light, but not to the intense sunshine. After blooming, the bulbs may be allowed a time of rest, removing them to a cool and shady place in the border, if desired, watering rarely. In early autumn repot, and after a few weeks of growth, water more freely. It does not, however, injure the plant to keep it constantly growing, and the best florists have very generally abandoned their former method of letting them rest during the summer. Cyclamen autumnale flore alba, white, and rubra, red, blossom in the autumn.
