Buddleja davidii variegata - Plant
Prompt removal of spent flower spikes during the growing season will usually encourage continued bloom until frost.
B. davidii cultivars are considered unfussy about soil type but they do prefer a free-draining soil. They require sun for at least part of the day and donâ€™t like deep shade. In areas with heavy clay it is probably best to improve the soil with plenty of compost and sharp sand or grit. Winter water-logging is the biggest problem. I usually dig a very deep planting hole, much deeper than the top soil and back fill with the sand/grit and compost as this helps with drainage. Many cultivars grow so quick that they will become strong enough to cope with occasional water-logging. They also do like slightly alkaline conditions so lime can be beneficial and it helps the production of the hairs that produce grey foliage in some cultivars. Limestone (10mm) chippings that are used for drives can be introduced in the planting hole which both helps drainage and keeps the soil from becoming acid.

- Always wear safety goggles; branches can whip back when released.Start with pruning shears for smaller growth. Use loppers, which look like giant, long-handle shears, for growth that is more than half an inch thick. A small pruning saw is handy, as it cuts on both the push and the pull.Deadhead religiously and keep beds clean.
