Bulbous-rooted, spring- and autumn-flowering plants. These plants can be grown almost anywhere, in the border, in groups on the rockery, or naturalized in grass.
Plant spring-flowering species in late autumn and winter, while the autumn-flowering species should be planted in August or September. They like an open, light rich soil.
To naturalize Crocuses in grass, holes should be bored 3-in. Deep and 2-in-apart and the bulbs planted, covering with ordinary soil, or a few turves may be lifted and the bulbs planted, afterwards replacing the turves. If grown in this way, the grase must not be cut until the foliage has died.
To grow in bowls, special fibre will be necessary and this can be purchased from any nurseryman. They should be grown in the cold frame or greenhouse, and when ready to flower they should be brought into the house. They will not, however, stand forcing to any great extent, and indoor culture of crocuses is not always successful.
Propagate by offsets removed from old bulbs in July and August and treated as old bulbs. Seeds may also be sown in sandy soil in autumn. Seedlings will not flowrr until they are three or four years old. Some of the best varieties for the amateurs garden are:
Baron van Brunoio, dark blue. Purpurea grandiflora, purple. Queen of the Blues, pure lilac. Kathleen Parlow, pure white. King of the Whites, white. Sir Walter Scott, violet and white. Dahlia. Excellent plants for bedding (dwarf types) and for use in mixed borders.
