Position: full sun
Soil: fertile, well-drained, neutral to slightly alkaline soil
Rate of growth: average Flowering period: July to August
Hardiness: hardy biennial
Large pale-purple or occasionally white, thistle-like flowerheads appear in July and August above spiny-toothed, grey-green leaves. This biennial, native Scotch thistle makes an architectural statement in a sunny gravel or wildlife garden. The ripening seedheads act as a magnet for goldfinches and the plant self-seeds freely.Garden care: Use beer traps or environmentally- friendly slug pellets to protect the tender young foliage against damage from slugs or snails.
