Okay I have decided today to shovel prune my four Stella De Oro daylilies. These four plants were blooming like crazy all spring/early summer and stopped on a dime a few weeks ago. All four plants have TONS of unopened buds. That never open. I have checked for thrips, spider mites, overwatering, underwatering, and I have officially given up. They get plenty of sun and are in very decent soil. Those buds just sitting there unopened for weeks are really driving me mad.
So my question is, if you were going to have space for four new perennials this late in the season what would you plant? I prefer something long flowering (or with really good foliage) that can take virtually all day sun. They will be located in a bed that will receive very limited amounts of water. Size is not really critical but prefer to keep it until three feet ideally.
