Ornithogalums

The Ornithogalums, or Stars of Bethlehem, are not general favourites in gardens, because of their seeding propensities, which make them difficult to keep within bounds. Several are very pleasing and deserve some attention, because of their white and green flowers. Umbellatum, the common species, is only suitable for the wild-garden, but the little tenuifolium is pretty, as also are fimbriatum and montanum. Nutans is pretty also, but increases too rapidly. Pyramidale is a fine plant about two feet high. They like a sandy soil and to be planted about two inches deep. None of the yellow Ornithogalums are hardy.

Oxalises

The Oxalises, or Wood Sorrels, are bright little plants, although their value is reduced by their flowers only opening in sun. There is a pretty lilac variety of O. Acetosella, our common Wood Sorrel, and Bowiei and floribunda, with rose flowers, are quite hardy in light soil. Lobata, a beautiful little yellow species, flowering in October, is also hardy, as well as the exquisite white enneaphylla. Tetraphylla, lasiandra, l. alba, and violacea may also be tried with every prospect of success. Give a sunny position in light soil, and if planted in autumn cover slightly the first winter.

PÆonias

The herbaceous PÆonias, which are such brilliant ornaments of our gardens in May and June, would require more space to do them justice than we can command. They like a rich, well-manured soil, inclining to heaviness and thoroughly trenched before planting in early autumn. After the plants are in position mulch the ground with rotten manure, and when growth is being made in summer give liberal applications of manure water to induce free growth. The crowns should be a little below the surface, and plant if possible where the sun does not reach them until a little before noon. The list of superior varieties is extremely extensive, and those thinking of purchasing PÆonias should either select the plants while they are in bloom, or from the catalogues of dealers who grow these flowers largely. The single forms are very beautiful also, though they hardly keep so long in bloom. Many of the species are also attractive plants, and where there is sufficient space a selection of these should be made and grown. The common Peony of old gardens is P. officinalis.

Ranunculuses

At one time a favourite florist's flower, the Ranunculus has fallen greatly out of favour, and there are now few named sorts grown. It is, however, well worth growing for its beauty as a garden flower and also for cutting. A bowl of pure white Ranunculi with the foliage of Heuchera Richardsoni, or some other dark-leaved plant, is a charming thing, and many equal beautiful effects can easily be produced. The florist's Ranunculus was derived from R. asiaticus, and there are flowers of almost all colours among the double varieties which have been raised. A good strain of mixed Ranunculuses will produce many good flowers at a small expense. The principal forms now grown are the Turban or Turkish and the Persian, which are varied in their colours. Those named R. asiaticus superbus are large and showy, if a little coarse to those accustomed to the more refined flowers of the others. They can be grown in an ordinary border well manured, and can be planted from October to February. In planting choose a dry day, and keep the crowns two inches below the surface. Care must be taken to keep the crown up, and to cover this with a little sand after planting. Cover with some litter in winter, and water freely when coming into bloom. Lift when the foliage becomes yellow, and dry off in a cool and airy place, storing the tubers in dry sand.

There are a few other tuberous-rooted species of Ranunculus worth growing in the garden. Of these the best are the double form of the native R. bulbosa which has yellow flowers; R. chÆrophyllus, yellow; R. monspeliacus, yellow; and R. millefoliatus grandiflorus, the same colour. These are easily grown in the border in ordinary soil.

Romuleas

Romuleas are remarkably pretty little bulbs with Crocus-like flowers, from March to July, and grassy leaves. They require warm, sunny spots on rockwork, and in cold localities should be grown in a frame. They like sandy soil. Among the best and hardiest are R. Bulbocodium, with blue and yellow flowers. The variety pylium is even prettier. ColumnÆ is pretty with its white flowers. Clusii, lavender, and speciosa, rosy violet, are both pretty. Plant in autumn two inches deep, and protect in winter.

Sanguinarias

S. canadensis, the only species, is a pretty little plant, known as the Bloodroot, Red Puccoon, or Red Indian Paint, and perfectly hardy. It has white flowers with a yellow centre in April, and the leaves are not fully developed until after the flowers. It likes a rich moist soil, but can be grown in the border. The best form is grandiflora, and the one called multipetala has many narrow petals. There is said to be a pinkish form.

Sternbergias

The Sternbergias are handsome autumn flowers with blooms like a glorified yellow Crocus, which appear before the leaves. The best for the open air is S. lutea angustifolia, a narrow-leaved variety of the common lutea. Others of much beauty are fischeriana and macrantha, the latter having very large flowers. In order to make them flower they need a dry, sunny position in soil with limestone or lime rubbish. They should be planted in summer about two inches deep.

Schizostylis coccinea

The Kaffir Lily is a valuable late blooming plant in a warm, sunny border, where it blooms in autumn, when its bright scarlet flowers in long spikes are much appreciated. Although it likes a warm position, it must not suffer from drought in its growing period. Plant in spring about three inches deep. It makes a good pot plant for a cool house.

TecophilÆas

The beautiful little TecophilÆas are quite hardy in light soils, but are, because of their scarcity, usually grown in frames or in pots in greenhouses. They have pretty Crocus-like flowers of blue and white, and should be planted in rich, light soil in a sunny position, well-sheltered from wind, or in a frame. Slugs are very partial to them, and must be carefully guarded against. The leading species are cyano-crocus and violÆflora.

Trilliums

The Trilliums, or Trinity Flowers, are very ornamental plants, and are so distinct in form that they please everyone. They like shade and a moist peaty soil. Grandiflorum is a general favourite, with its large flowers of pure white. There is also a rose-coloured form named grandiflorum roseum. Even finer than grandiflorum is sessile var. californicum, which is considerably taller, and has fine white flowers, those of the typical sessile being purple. Cernuum, erectum, erectum album, nivale, petiolatum, recurvatum, and stylosum are all pretty, the last being the latest to bloom, and well worth growing. Plant in autumn or spring, with the crown one or two inches below the surface of the soil.
