About this plant
This is a charming low-growing plant which presents columnar spikes of clear blue-purple flowers for weeks in summer. Best planted in a group for impact. The flowers are held on long upright spikes. When they have died, the warm-coloured brown calyces remain as an attractive feature. The leaves are oblong, coloured sea-green and form a solid foundation to the flowers. It is good in a border settings and can look appealing with the contrasting flat heads of yellow achillea forms such as 'Moonshine'.

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.
Spring - mid-late · Planting
Trim the plant
Trim the plant to give it a general tidy. This includes removing any lengthy or awkward shoots that make the plant look visually less attractive. Remove any spent flower heads at the same time.
Planting & general
Planting
Deadhead blooms during flowering season
Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.
The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.
Compost · Planting
Loam based compost + grit for repotting
Use a free draining loam based compost rather than one which has been modified to be 'moisture retentive'.
Alternatively prepare a compost using three parts of loam (John Innes no. 2 or 3) to one part of (horticultural) sand or fine (horticultural) grit.
