POTENTILLA RECTA 'WARRENII'
This vigorous and very old favourite produces strong clumps of divided foliage, above which arise large sprays of bright canary-yellow flowers over a long period throughout spring and summer. It may self-seed when happy but never becomes a nuisance here.
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.
