Gardeners are being advised to plant autumn crocuses, also known as colchicum, this July to ensure a display of stunning blooms from September through October. The flowers, which range from deep purple to pale pink, emerge without leaves, earning them the nickname "naked ladies." Despite the name, they are not related to spring crocuses but belong to the lily family.
When and how to plant
For optimal results, colchicum bulbs should be planted no later than early August. Plant them 8-10 cm deep, 15 cm apart, with the pointed end facing upwards. They can go directly into the ground or into containers filled with peat-free multipurpose compost. The bulbs thrive in moist but free-draining soil in dappled shade, ideally near trees, in grass, or in front of a border.
Care and precautions
Wear gloves when handling autumn crocuses, as every part is poisonous if ingested by humans or animals. The plant is low-maintenance: no pruning is needed, and foliage should be left to die back naturally after blooming. Watch for aphids and mould, but pests and diseases are generally not a concern. Propagation happens naturally, but offsets can be taken in summer after leaves die back.
Choosing varieties
When buying bulbs, avoid corms that feel soft or show white mould. Popular varieties include Colchicum 'Waterlily' for double pink-purple flowers, Colchicum autumnale 'Album' for pure-white, and Colchicum speciosum 'Album' for larger white flowers with green throats. Plant within the July-August window to avoid late or missed blooms.
For those who prefer other options, hydrangeas, dahlias, foxgloves, and wallflowers are good alternatives, according to BBC Gardeners' World.
