Buddleja

Buddleja fills gardens with fragrant, nectar-rich blooms that will attract butterflies, bees and other pollinators. These hardy shrubs are prized for their upright, arching growth and long-lasting flower spikes, which provide colour and structure from midsummer into early autumn. Flower colours range from deep purples to pinks and reds, creating a striking focal point in borders, beds and edges.

At J. Parker’s, we have a well-stocked selection of ready-to-plant Buddleja cultivars. ‘Black Knight’ is valued for deep purple spikes and vigorous growth, while ‘Royal Red’ produces rich red-purple flowers that attract a wide range of pollinators. Both are ideal for adding summer interest.

Where to plant Buddleja

These shrubs thrive in full sun with well-drained soil, tolerating fertile loams to moderately poor soils. A sheltered position is best in exposed sites. Upright growth can provide natural screening or structure. Prune after flowering to maintain shape, encourage new growth, and support next season’s flower spikes.

Companion plants

Pair Buddleja with summer-flowering perennials such as Echinacea, Salvia or Rudbeckia for vertical contrast and pollinator appeal. Ornamental grasses like Miscanthus or Pennisetum add texture and movement, while low annuals or summer bulbs at the base soften the display and extend seasonal interest.

Growing Buddleja

Plant in spring or autumn, enriching the soil with compost or well-rotted organic matter. Water regularly during dry spells to aid establishment. Deadhead spent spikes to prolong flowering, and prune hard in early spring to maintain a compact, bushy habit and vigorous growth. Buddleja delivers reliable summer colour, wildlife value, and low-maintenance structure.
