Highly ornate plant with heart-shaped foliage from which rise stems topped with very decorative steel-blue cones surrounded by a collar of spiky, scalloped leaves. Comes into its own at dusk when these amazing flower heads take on a ghostly, silvery-white hue! Brilliant for adding texture and contrast to the border and makes an excellent dried flower.

Sowing Instructions: Sow at any time of year except early-mid summer. Sow onto the surface of moist, free draining seed compost and just cover with vermiculite. Place in a propagator or warm place and maintain a temperature of 15-18C for 3 weeks, then move to the refrigerator (3-5C) for 5 weeks. After this, place in propagator again at 15-18C where germination should occur in 6-10 weeks. If it doesn’t, return to the refrigerator for a further 3-6 weeks. Check regularly whilst in the refrigerator and remove immediately if any have germinated.

Growing Instructions: When seedlings are large enough to handle, pot up individually into 7.5cm pots and grow on in a coldframe and plant out 30cm apart the following spring.
