Plant Profile: Buddleja davidii 'Harlequin'

The 'Harlequin' butterfly bush thrives in moist, well-drained soils and prefers partial to full sunlight. It's important to avoid overly wet or poorly drained areas, as excessive moisture can cause root rot. Once established, this plant has moderate water needs and is drought-resistant. While it can adapt to various soil types, it's advisable to enrich clay soil with compost.

Buddleja davidii 'Harlequin' is a variegated variant of Buddleja davidii 'Royal Red'. Like other spontaneous mutations, it may revert to its original green foliage under stress. To preserve its distinctive appearance, it's essential to prune away any non-variegated branches. In colder climates, the plant will die back to the ground, necessitating the removal of dead branches when new growth appears in spring. Since it flowers on new growth, pruning back to about a foot above the ground in spring is also recommended to maintain its shape, minimize twiggy growth, and encourage larger blooms.

While 'Harlequin' can be susceptible to capsid bugs, caterpillars, and spider mites, it is generally resistant to diseases.
