Head Gardener’s Highlights: July
Experience the colours and fragrance of high summer
July is a wonderful time to explore the arboretum, with vibrant wildflowers, spectacular flowering trees and shrubs, and an abundance of plants attracting bees, butterflies and other pollinators. The recent warm weather has produced some exceptional displays, so now is the perfect time to enjoy them while they’re at their best.
Wildflower Meadows Alive with Wildlife
The wildflower meadow in Seven Leys is thriving and full of life. On warm summer days, this beautiful area becomes a haven for insects, with grasshoppers, bees, butterflies and moths all taking advantage of the rich variety of nectar-rich plants. Look out for colourful drifts of ox-eye daisies, Lady’s Bedstraw, and both Common and Greater Knapweed as you wander through the meadow.
Ornamental Dogwoods in Their Summer Colours
One of the season’s standout features is the ornamental dogwoods. Cornus ‘Norman Hadden’ and Cornus capitata are now displaying their striking bracts, which have gradually transformed from creamy white to soft pink, creating beautiful focal points around the arboretum.
Hydrangeas and Summer Shrubs
July sees the hydrangea collection beginning to come into its own. Along the streams, Hydrangea aspera ‘Hot Chocolate’ combines dramatic dark purple foliage with delicate pink flowers, while Hydrangea serrata offers elegant blooms in shades of pink and soft red.
Along the Main Drive, the impressive Oak-leaved Hydrangea (Hydrangea quercifolia) is beginning to flower, with large, textured foliage providing the perfect backdrop to its lightly scented white blooms.
In Seven Leys, don’t miss the unusual Sambucus ‘Chocolate Marzipan’, admired for its rich dark foliage and distinctive marzipan-scented flowers. Nearby, Sambucus ‘Gate into Field’ is producing its large, creamy flower heads later in the season than our native elder.
Summer Flowers for Pollinators
Along the path beside the upper stream, Telekia speciosa (Heartleaf Oxeye) is beginning to flower, producing cheerful yellow, daisy-like blooms that are especially popular with bees and butterflies. Nearby, look out for clumps of Acanthus mollis (Bear’s Breech), whose bold architectural foliage is topped with elegant white and purple flower spikes near the bridge leading to the steps.
Her Ladyship’s Walk continues the summer display with the delicate white flowers of Hoheria, while the impressive Magnolia delavayi bears creamy-white, cup-shaped flowers among its glossy evergreen foliage. Bright yellow blooms of Genista aetnensis (Mount Etna Broom) and colourful Buddleja davidii in shades of deep purple and red complete this vibrant area.
Follow the Scent of Summer
Although their flowers may be understated, the lime trees are one of the highlights of July. Scattered throughout the arboretum, they fill the air with a wonderfully sweet fragrance that drifts through the grounds and adds another sensory dimension to a midsummer walk.
Whether you’re seeking seasonal colour, wildlife, photography opportunities or simply a peaceful stroll, July offers an abundance of reasons to visit Batsford Arboretum.
