I bought two buddleia this year, an "Ellen's Blue" and a "Pink Delight." The "Pink Delight" has grown quite tall with 5 or 6 giant plumes of flowers (each 12"-18") The "Ellen's Blue" has produced dozens of flowering plumes (each about 6") but the plant is only about half the height of the "Pink Delight." I planted them nest to eahc other and it looks a little strange. The Ellen's Blue was a more mature plant when I bought it. Can planting depth explain this behavior? Is it the way the "Ellen's Blue" was pruned? How can I encourage the Ellen's Blue to grow taller? thanks.
