- ‘A thistle that hugs the ground and provides delightful, lasting dried flowers for winter is the stemless Carline Thistle (Carlina acaulis).’
- ‘In France and Germany names meaning ‘wild artichoke’ are given to various thistles with edible heads, including the smooth carline thistle, Carlina acaulis, and milk thistle, Silybum marianum.’
