Bacopa 'Festival' (Chaenostoma cordatum) (Pot Size 12cm) sold by Boma Garden Centre

Festival Bacopa is one of those quietly effective summer bedding plants that pulls a display together without ever overpowering it. Its small, five-petalled white flowers, each with a soft yellow eye, are held just above neat, rounded green foliage, creating a light, airy cloud of colour that softens edges beautifully.Rather than dominating, Bacopa works as a unifying layer — weaving between more structural plants, spilling gently over the edges of pots and window boxes, and adding movement without weight. It pairs particularly well with pelargoniums, calibrachoa, nemesia, and osteospermum, where it lifts stronger colours and adds a clean, fresh contrast.In a North London setting, it’s especially effective in window boxes and terrace containers, where its trailing habit softens hard lines and brings a relaxed, natural feel to urban planting schemes.
