About this plant
This extraordinary plant has thumb-like flower heads, each surrounded by fearsome looking jagged spiked collars of lavender-blue, needled bracts. The colour is most intense at the centre, it fades, over weeks, to beige tints though the spiked foliage retains a silvered hue. The long stout flower stalks may tend to kink unless discreetly staked. This intense dramatic effect arises from a mound of thistle-like, white-veined foliage.

AutumnNow
Autumn-Winter · Outdoors
Keep roots drier in winter
This plant dislikes having 'wet feet' in the cold months of winter. Plants that are grown in moist or boggy soil should be lifted in autumn, and either replanted in a drier place for the winter or planted in a pot and given moderate water during winter.
Spring
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.
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.
Summer
Summer - early · Outdoors
Feed a general fertiliser
Where plants have moderate needs for nutrients, they can simply be given a general feed, fairly early in the growth season so that the growth has plenty of time to harden off before the cold weather.
Give plants a general boost with the application of a general purpose fertiliser which is spread around the root area of the plant, with amounts as directed on the feed label.
