Answer: Potentilla "Miss WiIlmott" should bloom lightly off and on all summer with the heaviest flush in late spring/early summer. In my experience it does best in only a moderately rich soil and will run to foliage if the soil is overly rich; it also prefers a well drained soil with plenty of sun -- in other words it tends to do well in the average sunny flower bed. In all probability it spent this summer settling in and will perform beautifully next summer. This is especially likely if they were very small plants to begin with.
