Crocus korolkowii is a striking species crocus, producing rich golden-yellow flowers marked with distinctive brownish-bronze speckles and stripes around the outside and base of the petals. Flowering very early in the year, often between January and March depending on the weather, it is a lovely way to introduce colour into the garden while winter is still giving way to spring.

Growing to just 4-10cm tall, this compact crocus is perfect for rockeries, gravel gardens, border edges and containers. It is also well suited to naturalising, where groups can establish over time to create an increasingly impressive early-season display.

About Crocus korolkowii

Native to Central Asia, Crocus korolkowii is a particularly attractive member of the species crocus group. Rather than the larger blooms associated with traditional Dutch crocuses, it produces neat, elegant flowers with plenty of character.

The petals are a strong golden yellow, while the outside of the flowers carries contrasting bronze to brown markings. These may appear as fine speckles, streaks or more concentrated patches towards the base. The markings are especially noticeable while the flowers are closed, giving the buds an attractive two-tone appearance.

Very Early Spring Flowers

One of the best reasons to grow Crocus korolkowii is its early flowering season. Depending on winter temperatures and local conditions, flowers can begin appearing from January and continue through February into March.

On bright days the flowers open to create little pools of golden colour close to the ground. Planting a generous group together produces the strongest effect and works particularly well alongside other early bulbs such as snowdrops, winter aconites and contrasting purple or white crocuses.

Growing Crocus korolkowii in the UK

Plant the corms during autumn in a sunny position. Choose soil that drains freely, particularly during winter, as prolonged waterlogging should be avoided. If your garden has heavy clay soil, a raised bed, rockery or container can provide more suitable conditions.

For an attractive display, plant the corms in informal groups rather than individually. Their short stature makes them ideal for the front of borders and other open positions where the flowers will remain visible.

Perfect for Rockeries and Containers

With a mature height of only 4-10cm, Crocus korolkowii is an excellent choice for rockeries and gravel gardens. Its bright flowers contrast beautifully against stone and gravel, while its narrow foliage takes up very little room.

It can also be grown in pots, troughs and other containers. Use a free-draining compost and position the container somewhere sunny. Planting several corms together will create a much more impressive display when they emerge in late winter.

Naturalising Crocus korolkowii

Crocus korolkowii is ideal for informal planting and naturalising in suitable well-drained areas. Groups can be planted beneath deciduous shrubs, around border edges or among other low-growing spring bulbs.

Once flowering has finished, allow the narrow leaves to remain until they yellow and die back naturally. The foliage continues to feed the corm after flowering and helps prepare it for the following year's display.
