June 2026 brings gardens alive with colour, scent, longer evenings, and beautiful seasonal planting choices.
June is the month gardeners most look forward to. This month, many flowering plants burst open en masse, filling the garden with colour and scent. It’s also the month of the longest day of the year. That brings plenty of opportunities to garden and sit outside late into the evening. There are plenty of plants to add to flower borders. Here are ten of the best for your June 2026 garden.
1. Lavandula angustifolia ‘Rosea’ (Lavender)
For June 2026, this lavender is a lovely choice for soft colour and scent. As its name implies, it produces rose-pink flowers, rather than the deep lavender colour of traditional species and cultivars. This cultivar is ideal for lining pathways and planting in flower borders. Its pretty pink flowers look wonderful alongside roses with pastel-coloured flowers.

2. Lonicera periclymenum ‘Rhubarb and Custard’ (Honeysuckle)
For June 2026, this honeysuckle suits smaller gardens beautifully. Honeysuckles have a reputation for being rampant growers, but happily this cultivar is the exception. It can be trained against fences and walls, or grown in containers up obelisks. The highly scented flowers are pink, fading to yellow, creating a two-tone effect. This gives rise to its cultivar name, ‘Rhubarb and Custard’. Later in the year, shiny red berries appear and provide late-season food for birds.

During this time, the plant is covered in daisy-like flowers. Its soft, spreading habit makes it ideal for the edge of borders. It is also useful for softening walls and growing in containers. This makes it a useful June 2026 plant for relaxed, informal borders.
