POTENTILLA THURBERI 'MONARCH'S VELVET'
Massed heads of deep raspberry red flowers shade to a crimson velvet centre on these long-flowering and long-lived specimens. Bright green crinkled foliage, reminiscent of strawberries, adds to this attractive illusion. An excellent form of Potentilla thurberi.
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.
