Onopordum acanthium
Scottish thistle
- Position: full sun
- Soil: fertile, well-drained, neutral to slightly alkaline soil
- Rate of growth: average
- Flowering period: July to August
- Hardiness: fully hardy (but short-lived)
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.

Q:
Can giant thistles can be grown in pots?
Are you able to advise me if giant thistles can be grown in pots and if so what sort of soil do the prefer?Asked on 6/12/2009 by Nigel Maudsley1 answer
A:
Hello there. The thistle will be much happier planted out into fertile, well-drained, neutral to slightly alkaline soil in the garden rather than being kept in a pot. I hope this helps. Helen Plant DoctorAnswered on 6/17/2009 by Crocus Helpdesk
