ZEPHYRANTHES ATAMASCO (106) ORNITHOGALUM ARABICUM (107) ORNITHOGALUM NUTANS (108)
[SPREKELIA] formosissima (Jacobæa Lily).—A fine Mexican plant, with roundish bulbs 2 to 3 inches in diameter, and narrow strap-shaped leaves 12 to 18 inches long. In the open air the irregular bright crimson blossoms, each about 6 inches across, appear about August, and never fail to attract attention.
Unfortunately, the Jacobæa Lily, of which there are a few colour variations, can scarcely be considered as perfectly hardy in the mildest parts of the British Islands. It often flowers, however, when the bulbs are planted out about the end of May or early in June, when danger from frost is practically over. The flowers often appear before the foliage, but the bulbs should not be lifted in autumn for storing until the leaves show signs of withering. New plants are secured from offsets.
[STERNBERGIA.]—Charming plants, with roundish bulbs about 2 inches in diameter, and strap-shaped leaves, which are in their prime sometimes with the blossoms, as in S. lutea, and sometimes long before the latter appear, as in S. macrantha. The bulbs should be planted in spring, 5 or 6 inches deep, in rich and well-drained sandy loam and leaf-soil. When in bold clumps the flowers present a charming sight, either in the grass, rock-garden, flower border, or margins of thin shrubberies. All kinds have beautiful crocus-like yellow flowers as shown in [Plate 33]. S. lutea (fig. 119), variously known as the "Winter Daffodil" and "Yellow Star Flower," is considered to be the "[Lily of the Field]" mentioned in the Scriptures. It blooms in September and October, the yellow flowers nestling amongst the leaves. There are several forms of it, differing chiefly in the size of the blossoms and width of the leaves. S. macrantha ([fig. 120]) is a still finer species, with flowers much larger than those of S. lutea, with which they appear in autumn. Other species are colchiciflora, the bulbs of which are only about an inch in diameter, and the pale-yellow sweet-scented flowers appear in autumn. S. Fischeriana also has bright golden-yellow blossoms, but differs from its relatives in producing them during the spring months—February onwards—instead of in the autumn.
[TECOPHILÆA] cyanocrocus.—This distinct and charming Chilian plant, popularly known as the "Chilian Crocus," has fibrous-coated corms and narrow wavy leaves. The beautiful Violet-scented, funnel-shaped flowers of a brilliant blue, with a white centre, appear in March and April, borne in loose trusses. (See [Plate 12], fig. 50.) The variety Leichtlini differs in having deeper blue flowers than the type, and without the white centre.
In the milder parts of the kingdom the Chilian Crocus may be grown in the open air in warm sheltered spots, such as on a south border at the base of a wall or fence. Rich sandy loam and leaf-soil is a good compost into which the corms may be planted, 6 to 9 inches deep, about September. In winter it may be necessary to give protection with litter, bracken, &c., in the event of severe frosts or continuous cold rains. The plants are most readily increased by offsets.
[TIGRIDIA] Pavonia (Peacock Tiger Flower).—There are several species of Tiger Flowers, but the one here mentioned, and its several varieties, are the most useful for the out-door garden. They have bulbs 1-1/2 to 2 inches in diameter, and plaited Gladiolus-like leaves. The blossoms, however, one of which is shown on [Plate 30], fig. 110, are of exceptional beauty and brilliance amongst bulbous plants, and although they do not last a long time individually, they nevertheless follow each other so rapidly that the plants are scarcely ever without flowers during the summer months. The coloured picture will convey a far better idea as to the colouring and blotching of the flowers than any printed description. There are other varieties of T. Pavonia besides the one shown on the Plate. Perhaps the best are grandiflora, very large and brilliant; conchiflora, yellow blotched with purple; Wheeleri, deep red; and alba, pure white spotted with purple.
The Tiger Flowers are natives of Mexico, and therefore cannot be grown successfully in the open air in all parts of the kingdom. In the mildest parts, however, the bulbs may be left in the ground during the winter months, care being taken to protect them with leaves, litter, &c., during severe weather, or from heavy cold rains. In less favoured spots, where they nevertheless blossom out of doors in summer, the bulbs may be taken up about the end of October when the foliage has withered, and they may then be stored in frost-proof places in sand until the following April or May. Whenever the bulbs are lifted the offsets should be detached to increase the stock. The warmest, most sheltered, and sunniest spot in the garden is obviously the best place for Tigridias. In addition to this the soil should be a well-drained sandy loam enriched with old cow-manure and leaf-soil. During active growth, and especially in the hot dry seasons, it is necessary to keep the plants well-supplied with water, otherwise the results are likely to be the reverse of satisfactory.
[TRITONIA].—This genus contains a handsome group of plants with fibrous-coated corms, like those of a Gladiolus, but much smaller. The plants formerly known as Montbretia are now also included in this genus, but the corms in some cases (e.g., M. crocosmiæflora) have slender creeping rhizomes, from which new corms are developed by the end of the season. The leaves are more or less like those of a Gladiolus, but somewhat narrower, and often curved, while the showy blossoms are borne in slender graceful spikes, that are very useful for cutting.
