About this plant
Here's an ornamental onion that has interesting blue-green foliage with a metallic hue. The strappy leaves, often mottled purple, come in pairs. The flower head, produced during June and early July, is delightful: white to lilac grey and composed of many, tiny, spiky looking flowers, like a lacquered dandelion clock. These alliums are attractive once the flowers have faded and the head has dried. It does regrettably leave a bare space, once the ample spreading leaves have died down.

Autumn · Planting
Remove offsets to create new plants
Offsets are small plants or shoots that develop around the parent plant. They should have developed a root system of their own before they are detached. They can be planted directly, or grown in pots if so small they could be 'lost' in the garden.
Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
