Best uses

This beautiful bulb looks great in a pot or incorporated into a rockery or mixed plantings en masse. They look great coming up through gravel mulch between other plants.

Physical characteristics

Deciduous bulb that grows up to 15cm tall.

Flowers and foliage

A spring flowering bulb with stunning scented purple blue flowers with a red eye and strap like green foliage.

Preferred site

Prefers full sun to partial shade with free draining soil.

Preparation for planting

Poorly drained soils can be improved by forming raised beds and incorporating coarse sand or gravel. A light application of slow-release fertiliser gives good results. A light dressing of sulphate of potash will improve flower quality and increase resistance to leaf spotting diseases. Avoid fertilisers which contain blood and bone or are high in nitrogen. When planting bulbs, cover with soil to twice the depth of the bulb.

Maintenance tips

Deciduous bulbs must be allowed to complete their full cycle of growth with leaves drying off naturally. If leaves are tied up into a knot or removed prematurely, their nutrients will not be transferred to the storage organs and there will be weaker growth and less flowering next season. Annuals may be grown in the same ground after the bulbs have died down. Bluebells usually resent disturbance and flower best when they have formed large crowded clumps of bulbs. The majority of bulbous plants deteriorate in vigour and flowering when overcrowded and become more susceptible to disease. Lift and replant every three or four years.

Fertilise with an organic-based fertiliser in spring at a handful per square metre or less.

Pests and diseases

Generally pest and disease free.
