I don't pay much attention to if a daylily is a bud builder. What I mean is don't try and look for bud builders to add to the garden. But I must have some. I do know VT HOME CAMPANION is a bud builder as I have seen that on years past. Plus just this morning I was looking at WESTBOURNE WHIPPERWILL CALL which has a bunch of small buds. I just know those weren't there before so it is bud building.
