About this plant
The foliage is striking with slender, long leaves, cream ribbed and with deep slim lobes that point forward like shark's teeth. They are coloured a softly silvered-green and need space to express themselves. The small thistle-flowers, coming from June to September, if rigorously deadheaded, are not coloured blue as the name suggests, but are red-purple, rather like the fading tones of the old red garden roses. Worth growing for the charm of the whole plant.

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 - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
