Summer Lilac Buddleja is a deciduous woody perennial shrub belonging to the figwort family, originally from China. This plant is notable for its striking silver foliage, which beautifully contrasts with darker green plants in the garden. Its shoots are adorned with soft, silvery hairs. To thrive, it needs protection during harsh winters, as it may die back to the ground but typically regrows in the spring. For optimal bushy growth, it is advisable to prune it back significantly each spring. Propagation can be achieved through division in the fall or by taking softwood cuttings in the spring. This shrub is resilient to drought and pollution, although it tends to grow at a slower pace compared to B. davidii.

In terms of pests and diseases, it has the potential to become weedy.
