New Zealand flax

This striking perennial from New Zealand holds the Royal Horticultural Society's prestigious Award of Garden Merit (AGM), which is for plants of outstanding excellence. It makes a tall clump of spiky, upright, dark green leaves which are blue-green underneath. In summer, stiff stems of dull red, tubular flowers are produced. Grow in a sunny spot in moist but well-drained soil. Plants are half hardy so in colder areas they will need to be overwintered in a frost-free place. Good in a warm, seaside location.

Looks good with:

Eryngium x oliverianum
Agapanthus 'Castle of Mey'
