About

Buddleja x wardii is a bushy, deciduous shrub that can reach heights of up to 4 meters. It features lanceolate, green leaves that provide a lush backdrop for its floral displays. Throughout the summer months, it produces short clusters of fragrant, lilac-hued flowers. This plant is a naturally occurring hybrid, resulting from the cross between Buddleja alternifolia and Buddleja crispa.
