Description
Onopordum acanthium
The Scottish Thistle is a fantastic, architectural biennial for the back of borders or as a security barrier! Not quite a native, but naturalised from Europe. In the first year seeds produce very grey, hairy rosettes of leaves which grow in the second year to over 2m tall. Both leaves and branched stems are white, hairy and fiercesomely spikey. Flowers mid to late summer, purple thistle heads sometimes over 5cm diameter. Sow in autumn or spring in normal well drained soil, in sun or part shade. Lightly rake in.
