With an impressive reddish-purple flower head 7cm across with woolly-haired bracts, the "Woolly thistle" is our tallest, most impressive, and indeed the rarest UK native thistle, displaying from July to September. It is perfect for a mid-border statement when its bold stature will also benefit the host of pollinating bees and other insects that love its rich nectar.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
