I have personally had good experiences with "Endless Summer". The fantastic part of this one is that you can cut it back to 2 foot size every spring if you like and it still manages to put out loads of flowers. In fact, if you reduce the bush to 4-6 thick canes (stems) the flowers are even bigger.

Add lots of peatmoss sphagnum and iron sulfate to the soil and they bloom blue. Use regular garden loam plus a dusting of lime once per year, and they are bright pink.

If they are white (when they should have been blue or pink .. some are white naturally) it is typically lack of fertilizer and/or you are letting the plant go through excessive dry/wet cycles. Try to mulch heavier, and/or transplant to shadier spot, and water more frequently and deeply.
