This sun-lover comes in hues from pure white to deepest purple. From midsummer until frost, butterfly bush earns its name as hordes of winged beauties flit from flower to flower in search of nectar. The lanceolate leaves are 10 to 12 inches long and white or grayish underneath. The honey-scented flowers are deep purple and grow in spikes, from July to October.
