About this plant
From an impressive, spiny foliage fortress arise neat thistle-flowers. These sit on spiky green bracts enfolded within slim lance-shaped leaves. The flowers are composed of masses of upright, cream stems surmounted by dusky pink threads, all standing fiercely to attention. The large, deep cut, spine-tipped leaves, bright green with cream central ribs, make for an intimidating base. It flowers in July and August and is best in a wild garden or flower meadow.

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.
