Buddleia Plant, Purple/ Lavendar (High Bentham LA2)

This will be a large (very tall)shrub with with purple sweet smelling panacles. Butterflies and bees adore it. This is a baby that seeded itself and survived the winter in my flower box. (less than a foot tall now), but will be large by the end of the season. It will be either pinkish purple or violet lavendar colored. (I have two, not sure which one this is the offspring of) Trying to save it from the compost bin, if anyone is interested? If you want it, please respind with possible collection day time. Collection only from High Bentham.
