Beautiful, bluish-violet, goblet-shaped flowers with deep blue veins from September to November, followed by narrow, mid-green leaves. This popular autumn-flowering crocus is ideal for naturalising in a sunny shrub border among deciduous shrubs. Often the earliest autumn crocus to bloom, it soon increases to form large colonies.
Plant bulbs in naturalistic drifts 10cm (4in) deep.Crocus speciosus tends to flower in early autumn, so if bulbs are planted from mid-summer to early autumn, they will usually bloom in their first year. Alternatively, if planted from mid- to late autumn, they typically won’t flower until the following year, however they will often have shoots (and possibly spent flowers) already present. In this case, keep the shoots intact, but plant the bulbs at the normal depth. The shoots may extend above the soil level, but the bulbs will continue to flourish, and fall into a normal growth pattern in subsequent years. Where bulbs are planted in grass do not cut the lawn until after the leaves have died back.
