Cultivation Instructions

Alliums perform very well with early flowering perennials and are also popular with bees and butterflies. Alliums will naturalise very well in most well drained soils. This variety will with stand some water logging of the soil. Cultivate soils to a depth of 15cms and plant bulbs with the pointy bit facing upwards. Bulbs should be planted at a depth of 10cms.

Feed bulbs with bone meal or similar during the flowering period to ensure they remain health for years to come. Plant in areas that are not exposed to the worst of the elements and in soils that have not been freshly manured. Regularly feed during the growing season with foods such as well rotted manures, Tomato feed and bone meal.

AGM= Awarded a Garden Merit by the Royal Horticultural Society for its superb garden performance.
