TANACETUM PARTHENIUM 'MALMESBURY'
These curious propeller-like flowers produce stubby white tubular petals which surround the yellow disc on this unique and unusual form which produce a shimmering effect when wind moves them. The name derives from Malmesbury in Wiltshire where it was found by Martin Cragg-Barber of the Natural Selection nursery.
For best results, sow seeds 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. However, we sow most seeds in an unheated greenhouse and wait for natural germination as many seeds have built-in dormancy mechanisms, and often wait for spring before emerging regardless of when they are sown. But spring sowing will obviously give them a full season of growth if successful germination occurs.
