I have 4 large mature Rhododendrons around my front porch, 3 of which are covered with blooms but the 4th is covered with flower buds that do not open. This happens every year. Otherwise the plant looks just like the other 3. Since they are all basically on the same side of the house (East/Northeast) with the same amt. of sunlight, rainfall, & (non-)fertilization I wonder if there is a logical reason why these flowers do not open.
