Product description
As a compact standard tree, the Buddleja 'Lila Sweetheart' makes a delightful focal point. Its true charm is revealed from mid-summer through to autumn, with an abundance of tapered, lilac-purple flower heads. These dense clusters of honey-scented blooms are a living feeder for pollinators, bringing a constant stream of butterflies and bees to the garden. To get the most from this sun-lover, give it the brightest spot you have. Throughout the summer, it appreciates consistent watering, but for winter survival, it is vital to ensure the roots do not sit in cold, wet soil. It isn't a hungry plant; a single bloom-boosting feed applied during the main flowering period is ample for the entire season. As such, it's an eye-catching addition to borders or containers, where its soft, grey-green leaves and trained, single stem provide structure and elegance.
To create a complete and layered patio display, consider underplanting your Buddleja tree with companions that enjoy similar conditions. Since the 'Lila Sweetheart' thrives in full sun and well-drained soil, choose other plants that appreciate the same. For a classic, bee-friendly combination, the purple flowers and grey foliage of English Lavender (Lavandula angustifolia) at the base make a wonderful partner. These additions create interest at a lower level and complement the tree's elegant form.

Top Tip
Don't be afraid to prune the 'head' of the tree back hard in early spring. This is the secret to a spectacular display of large flower spikes each summer.
How to Water
Water regularly during summer, especially in dry spells. Reduce watering significantly in winter, allowing the soil to stay on the drier side. Prune the entire 'head' or canopy back hard to a short framework in early spring (March). This is the most important task for a good display. A single feed with a high-potash fertiliser (like tomato feed) in mid-summer is sufficient.
How to Plant
Choose a location in full sun with well-drained soil. Dig a hole twice the width of the pot. Add horticultural grit to the bottom of the hole and mix some with the backfill soil. Place the tree in the hole so the top of its rootball is level with the soil surface. Backfill with the soil/grit mix, firm in gently, and water thoroughly.
