Description

Massive panicles composed of countless golden-yellow flowers adorn this gigantic specimen when it flowers in early summer, atop its strong stems and basal rosette of grey-woolly leaves. Although this large and impressive short-lived perennial sometimes dies after such a show-stopping flowering, it always seem to make enough self-sown babies to keep going constantly in subsequent years.

Sowing Advice

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.
