About this plant
An allium of wispy charm this sits on the intriguing borderline between 'weed' and ornamental'. Long, slender, generally upright stalks hold irregular heads of yellow flowers. The flower head is roughly oval in appearance with individual little oval flowers that have protruding cream-coloured stamens. The flowers arise from whiskered bracts. Dead stems whorl like fairy hay at their feet and the whole has an erratic charm. This varies between 10 cm to 25 cm in height and flowers during July and August.

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 during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
