This past May I purchased a ground cover that has had only a few of the advertised little pale blue flowers all summer. Its name is Isotoma fluviatilis (Blue Star Creeper). Wary though I am about introducing a creeper, I am interested in having little edging plants and in reducing the amount of visible mulch in parts of the garden.
Nearby is a pink Clematis without a name. Never a strong bloomer, it has managed two new flowers in this last week before fall arrives.
