Hyacinthoides hispanica

Deciduous bulbous perennial growing to 40cm tall.

Erect strap-shaped glossy green leaves which quickly form a large clump are produced from fleshy white tubers. Delicately scented stems of hanging bell-shaped blue flowers with blue anthers are borne in spikes in spring. White or pink flowers can also occur from this species.

Easily grown in average, well-drained soil in full sun to part shade.

Bluebells don't mind a sunny or shady situation but need well-drained soil to grow and flower well. 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.

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.

Generally pest and disease free.
