What’s in Bloom

Aesculus parviflora (bottle brush buckeye) in bloom.

Summer is here at the Holden Arboretum, and the blooming continues! This month there is plenty to feast your eyes on in the gardens. Be sure to enjoy the colorful array of Hydrangeas (Hydrangea arboescens, H. quercifolia, H. paniculata, H. macrophylla), daylilies (Hemerocallis) and astilbes (Astilbe cultivars and Astilbe chinensis) as you make your way through the Display Garden, Arlene and Arthur S. Holden Jr. Butterfly Garden, Helen S. Layer Rhododendron Garden and the Linda and Eliot Paine Rhododendron Garden as well as at Lantern Court. If this spring ignited your infatuation for rhododendrons then take a stroll through the rhododendron gardens once more to enjoy the deciduous azalea hybrids (Rhododendron ‘Weston’s Lemon Drop’, ‘Pennsylvania’, ‘Framingham’, ‘July Joy’, and ‘July Jingle’).

A closer look at the flowers of the bottle brush buckeye.

The bottle brush buckeyes (Aesculus parviflora and Aesculus parviflora ‘Rogers’), a considerably sized deciduous shrub related to our state tree, the Ohio Buckeye (Aesculus glabra), can be seen coming into bloom along the entrance drive, in the Hedge garden, and in the Holden Butterfly Garden. Do not miss the Hibiscus ‘Tosca’, a rose-of Sharon hybrid with large lavender-pink flowers in the Display Garden and Holden Butterfly Garden. While you are there be sure to take in the beauty of the water-lilies (Nymphaea) in bloom at these gardens and at Lantern Court.

There is no shortage of herbaceous perennials in bloom this July; you and our pollinators are sure to enjoy the Stokes asters (Stokesia laevis), Shasta daisies (Leucanthemum x superbum cultivars), black-eyed Susans (Rudbeckia fulgida, R. hirta), bee balm (Monarda didyma, M. fitulosa, and hybrids) and purple coneflowers (Echinacea purpurea and hybrids) blooming in the Display, Holden Butterfly and Prairie gardens. Additionally, in the Prairie Garden, the Queen-of-the-Prairie (Filipendula rubra) will be gracing the landscape with showy pink plumes.
