What's In Bloom

Hibiscus Midnight Marvel rose mallow In August, marsh and rose mallow (Hibiscus moscheutos cultivars and hybrids) are in bloom around the ponds in the Display, Rhododendron, and Butterfly Gardens where water lilies (Nymphaea) are flowering.

 

In the Arlene & Arthur S. Holden Jr. Butterfly Garden, the tall ‘Autumn Sun’ coneflowers (Rudbeckia ‘Autumn Sun’) preside over a riot of bloom including blazing stars (Liatris), butterfly bushes (Buddleia), garden phlox (Phlox paniculata), orange coneflower (Rudbeckia fulgida ‘Goldsturm’), and the sweetly fragrant summersweet (Clethra alnifolia). In the Prairie Garden, don’t miss the yellow flowers of prairie dock (Silphium terebinthinaceum) on their tall flower stalks and the compass plant (Silphium laciniatum), species of Silphium (sill-fee-um) that goldfinch are attracted to.

 

Silene regia in Myrtle S. Holden Wildflower GardenIn the Myrtle S. Holden Wildflower Garden and the Holden Butterfly Garden enjoy the bright red Royal catchfly (Silene regia), cardinal flowers (Lobelia cardinalis), and the cool blue lobelia (Lobelia siphilitica). In the Sally Gries Entry Beds along Sperry Road and inside the east gate of the Helen S. Layer Rhododendron Garden the late panicle hydrangeas (Hydrangea paniculata ‘Tardiva’) will be in bloom by mid-to late August.

 

Check out the orange flowers of Crocosmia ‘Emily McKenzie’, the purple flowers of lilyturf (Liriope platyphylla), the rosy-purple flowers of Allium ‘Millennium’, and the white flowers of the chaste-tree (Vitex agnus-castus ‘Silver Spire’) in the Display Garden.
