Do Non-Davidii Buddleias Self-Seed? (Golden Glow, Salviafolia, Lindleyana)

Will Buddleia × weyeriana 'Golden Glow', B. salviifolia, and B. lindleyana self-seed and spread like B. davidii?

Yes—Potentially

All Buddleias produce seed after pollination. Given bare soil and favorable conditions, volunteer seedlings can appear. However, germination is inconsistent—often "hit or miss."

Better Propagation Methods

• Collected seed: Sow in spring in multi-purpose compost.
• Softwood cuttings: Late summer; overwinter in cold frame; plant out next autumn.

Management Tip

Deadhead spent flowers to prevent seeding AND encourage rebloom. If you want volunteers, leave a few flower heads and see what happens.
