I hope my crossvine will bloom, someday, but I do not expect anything more than a massive Spring bloom and, perhaps some weak follow up. I have the native honeysuckle, Lonicera sempervirens( I think!), in several varieties and, while not evergreen here, flushes of blooms occur from Spring to frost, in repeating waves. I am interested in the new sort,'Major Wheeler', but the 3 types I have are dependable. Two evergreen vines I am growing, neither meeting your desires too closely, are Clematis armandi and Gelsemium sempervirens. Do not choose too quickly, as there are many aggressive vines, some blooming periodically, most of their growing season. Akebia, Bignonia and Wisteria can be too vigorous.
