A highly ornate border plant with heart-shaped basal foliage from which rise stems of many decorative steel-blue cones surrounded by a collar of prickly, scalloped leaves. During the summer the foliage transforms from mid green to silvery-grey. Wonderful for dried arrangements, especially at Christmas. Plants can be short lived but often self seed before dying. Height: 90-100cm (36-40in).

Sow in trays, pots, etc of good seed compost in a propagator or warm place to maintain an optimum temperature of 65-70F (18-20C). Surface sow and just cover with vermiculite. Do not exclude light. Sowing Time: February to July. Germination can be slow. After sowing, seal container in a polythene bag and leave at 60-65F (15-18C) for 2 weeks, then place in a refrigerator (not freezer) for 3-6 weeks. After this return to the recommended germination temperature. If germination does not occur in 6-10 weeks return to the fridge for a further 3-6 weeks. Examine regularly whilst in the fridge and remove immediately the seeds show signs of germinating.

Transplant seedlings when large enough to handle into 7.5cm (3in) pots. Grow on in a cold frame and plant out the following spring 30cm (12in) apart in full sun.

Prefers a rich, light, well drained soil.
