Description – Bees and other insects just love these beautiful big papery flower heads which open up to measure 15cm (6in) across! Their distinctive prickly leaves and stems are a good defence against pests! Plants grow well in a dry, sunny position in beds or borders.
Sowing – Sow outdoors where they are to flower. Prepare the ground well and rake to a fine tilth. Sow 0.5cm (¼in) deep. Keep the ground moist.
Growing – Thin seedlings out, allowing 25cm (10in) between plants. Deadhead regularly to prolong flowering.
Flowers – July to August
