I am going to order another buddleia from Park Seed, Honeycomb. This one has lovely buttery blossoms and an even stronger fragrance. I did have one earlier in my gardening career and the florets on that one were twice the size of my purple plant. And, the scent was even more heady. I kept cutting branches of flowers to have in the kitchen so I could enjoy the color, the shape, the design, the scent, well, just about everything about these wonderful additions to any garden.
Buddleias prefer full sun, but can stand a bit of shade. This is another shrub that needs a hard pruning in the early spring. I cut mine back to about 10 inches. When grown in Florida this shrub can reach heights up to 12 ft. during its growing season.
