Ixiolirions

Few people seem to grow the Ixiolirions, which are pretty summer blooming bulbs with umbels of lilac or blue flowers on stems about a foot high. This is unfortunate, as they are of pleasing appearance, though it is to be regretted that they are among those troublesome bulbs which are almost hardy, yet not absolutely to be depended upon in our climate. If planted in the open, this ought to be done in spring, and the bulbs lifted in autumn, and stored in dry sand, but it is more satisfactory to grow them in a frame or cool greenhouse in pots of loam, leaf-soil, and sand. There are two species—montanum and kolpakowskianum, the latter having a smaller bulb and shorter segments. The variety tataricum is considered a separate species by some botanists.

MorÆas

MorÆas are charming plants resembling the Irises, and are of bright colours, and generally very fragrant. They should either be grown in a frame with some winter protection, or in a cool greenhouse or conservatory planted out in rather sandy soil or in pots. Out of some sixty species, there are few not worth growing, but corms of only a limited number are purchasable in the ordinary course, and the best of these are named as a guide. They are often found about six inches high, but frequently grow much taller. Edulis has bluish-white flowers; iridioides, white, spotted yellow; papilionacea, pale-blue, spotted dark-blue; spathacea (syn. Dietes Huttoni), yellow; and tricuspis, greyish yellow and brown. Robinsoniana, also called Iris robinsoniana, needs a greenhouse, and has white flowers and handsome leaves with the habit of Phormium tenax. The genus now includes the Vieusseuxias and Dietes, which are sub-genera.

Ornithogalums

It is singular that the half-hardy Ornithogalums are so little grown, as they are very easily managed in a frame or unheated greenhouse, and will even do in a warm border in the south. They like a light soil and a sunny position, and to be well ripened after flowering. The prettiest of the half-hardy species are O. aureum, yellow; O. arabicum, white with almost black centres, a very effective plant; and the pure white O. revolutum They may be planted about three inches deep.

Oxalises

The tender Oxalises or Wood-Sorrels, are deserving of more attention from those who have sunny frames or unheated greenhouses, or even a sunny window, where these flowers can open, for all are sun-lovers. They like a light, rather sandy soil and may be planted in autumn or early spring about two inches deep. They are too numerous to detail, but I may name the following as all worth growing, although the list might be considerably extended. Arenaria, violet-purple; articulata, mauve; Barrelieri, yellow; elegans, purple; hirta, red; valdiviensis, yellow; variabilis, white or red; and versicolor, white and red. Those named among the hardy bulbs can also be grown under glass.

PhÆdranassas

Although generally grown as greenhouse bulbs, the PhÆdranassas, or Queen Lilies, may be grown in mild districts as frame bulbs, by cultivating them in rather heavy soil, keeping them as dry as possible in winter, and covering the glass of the frame with some canvas or a mat. Some succeed with them in the open, but they there need a position below a south wall and to have some protection in times of severe frost. They are also suitable plants for the greenhouse, where they can be grown in pots and rested in winter. They have umbels of pretty, reflexed flowers, and grow about one and a half feet high. The most suitable for frame cultivation are chloracea, yellow, and sweet-scented; schizantha, vermilion, yellow, and green; and ventricosa, yellow. They may be planted in spring about five inches deep in a frame, or six inches if in the open.

Pancratiums

Although the two Pancratiums named below are hardy in the milder parts of these islands, it is more prudent to treat them as plants which need frame cultivation throughout the greater portion of Britain. A warm, sunny border under a south wall is the place for them in the open garden, and in frames it is desirable to give them a similar position. They should be planted with the neck about a foot deep in the open and two or three inches less when in a frame. They belong to the Amaryllis family and have charming white flowers. The hardiest and most easily grown is P. illyricum, but P. maritimun has finer flowers. They like a light soil, and plenty of water while in growth.

Tigridias

Tigridias are among the most brilliant of summer bulbous plants, but though they have been established in some southern gardens, they are not generally hardy in Britain. The greater number in cultivation are varieties of T. Pavonia (syn. grandiflora) and these are very beautiful, their only fault being the short time the flowers last. The type has scarlet petals and a yellow, crimson-spotted cup, but there are a number of varieties ranging from white, through almost rose to lilac, pale yellow and orange yellow. Immaculata alba, Immaculata lutea, and the new "Nankin" are among the latest introduced. Van Houttei (HydrotÆnia Van Houttei) has brown and yellow flowers and is rather more delicate, and should have a frame or greenhouse. Violacea and Pringlei should have similar treatment. All may be potted and grown in a greenhouse if desired. Plant in April or May.

Zephyranthes

Reference has already been made to Z. Candida among hardy bulbs. A few others may now be mentioned for frame or cold greenhouse cultivation. These are strangely neglected by amateurs, as their pretty crocus-like flowers are exquisitely beautiful when open. Generally speaking, I should recommend their being grown in pots in the greenhouse, where they can have a sunny position near the glass. The best of those known for the frame or cold greenhouse are Andersoni, which grows about four inches high, and has yellow or coppery flowers about May; Atamasco, white, tinted pink, grows about nine inches high, and blooms about the same time; carinata, rose, about one foot high, and flowering in May; gracilifolia, about a foot and a half high and blooming about January; rosea, six inches high and flowering in May; and versicolor, rose and white, about six inches high. These Zephyranthes like a turfy loam with a little sand and well decayed manure or peat. They are propagated by offsets and should be repotted occasionally. The night-blooming Cooperias require similar cultivation.
