CROCUS , a botanical genus of the natural See also:

order See also:Iridaceae, containing about 70 See also:species, natives of See also:Europe, See also:North See also:Africa, and temperate See also:Asia, and especially See also:developed in the dry See also:country of See also:south-eastern Europe and western and central Asia. The See also:plants are admirably adapted for climates in which a See also:season favourable to growth alternates with a hot or dry season; during the latter they remain dormant beneath the ground in the See also:form of a See also:short thickened See also:stem protected by the scaly remains of the bases of last season's leaves (known botanically as a "corm"). At the beginning of the new season of growth, new See also:flower- and See also:leaf-bearing shoots are developed from the corm at the expense of the See also:food-stuff stored within it. New corms are produced at the end of the season, and by these the plant is multiplied. These crocuses of the flower See also:garden are mostly horticultural varieties of C. vernus, C. versicolor and C. aureus (Dutch crocus), the two former yielding the See also:white, See also:purple and striped, and the latter the yellow varieties. The crocus succeeds in any fairly See also:good garden See also:soil, and is usually planted near the edges of beds or See also:borders in the flower garden, or in broadish patches at intervals along the mixed borders. The corms should be planted 3 in. below the See also:surface, and as they become crowded they should be taken up and replanted with a refreshment of the soil, at least every five or six years. Crocuses have also a pleasing effect when dotted about on the lawns and grassy See also:banks of the See also:pleasure ground. Some of the best of the varieties are:—Purple: See also:David See also:Rizzio, See also:Sir J. See also:Franklin, purpureus grandiflorus. Striped: See also:Albion, La Majestueuse, Sir See also:Walter See also:Scott, See also:Cloth of See also:Silver, Mme See also:Mina. White: See also:Caroline Chisholm, Mont See also:Blanc.

Yellow: Large Dutch. The species of crocus are not very readily obtainable, bud' those who make a specialty of See also:

hardy bulbs ought certainly to See also:search them out and grow them. They require the same culture as the more See also:familiar garden varieties; but, as some of them are See also:apt to suffer from excess of moisture, it is advisable to plant them in prepared soil in a raised See also:pit, where they are brought nearer to the See also:eye, and where they can be sheltered when necessary by glazed sashes, which, however, should not be closed except when the plants are at See also:rest, or during inclement See also:weather in order to protect the blossoms, especially in the See also:case of See also:winter flowering species. The autumn blooming kinds include many plants of very See also:great beauty. The following species are recommended: See also:Spring flowering:— Yellow: C. aureus, aureus See also:var. sulphureus, chrysanthus, Olivieri, Korolkowi, Balansae, ancyrensis, Susianus, stellaris. See also:Lilac: C. Imperati, Sieberi, etruscus, vernus, Tomasinianus, banaticus. White: C. biflorus and vars., candidus, vernus vars. Striped: C. versicolor, reticulates. Autumn flowering:— Yellow: C. Scharojani. Lilac: C. asturicus, cancellatus var., cilicicus, byzantinus (iridiflorus), longiflorus, medius, nudifforus, pulchellus, Salzmanni, sativus vars. speciosus, zonatus.

White: caspius, cancellatus, hadriaticus, marathonisius. Winter flowering:—C. hyemaeis, laevigatus, vitellinus.
