Potentilla Nepalensis ‘Helen Jane’ – (Nepal cinquefoil)
Helen Jane is a smaller cultivar. It has compact heads which have bright pink single flowers with crimson eyes. The petals are like crepe paper. The flowers appear in summer, and it likes full sun . The plant is frost tolerant, and can withstand a moderate amount of drought, liking soil to be well drained and even a little on the dry side . It is a good candidate for a planter, but is equally at home in the front border.
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, one can 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.
