CROCUS , a botanical genus of the natural
See also:Iridaceae, containing about 70
See also:species, natives of
See also:North Africa, and temperate
See also:Asia, and especially
See also:developed in the dry
See also:country of 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 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: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 pleasure ground . Some of the best of the varieties are:—Purple:

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 case of 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 .
