Our featured plant: Hydrangea quercifolia 'Sikes Dwarf'

Perennials that cool down a hot summer day, refreshing foliage, soothing blooms, last chance to take advantage of our summer sale!

Bring sparkling beauty to your August plantings

Perhaps you’re looking for some soothing floral or foliar accents on a hot summer day! We’ve found that snowy white, clear pink, pale yellow and deep blue blooms coupled with silver, bluish green or emerald-toned leaves become refreshing counterpoints to warmer-hued flowers. They offer a place where your eye can rest, much like cleansing your palette when tasting wine. These shades meld the spicy-colored flowers of many Achillea, Crocosmia, Dahlia, Geum, Helenium, Kniphofia, Rudbeckia and Salvia.

Our next guided Saturday Strolls is August 19th., followed by September 16th & October 7th. We hope you’ll come visit us this summer.
