Special Attributes

A super-hardy, adaptable and very easy to grow North American native flowering shrub, 'Ruby Spice' Summersweet, also called Sweet Pepperbush, is the darkest pink of all of varieties we've ever seen. We like the common name Summersweet best because it describes the deliciously fragrant flowers that smell like sweet cotton candy...not pepper! In summer, LOADS of bottlebrush-like flowers are irresistible to hummingbirds, butterflies, and other pollinating insects. The color show continues in fall when the handsome green foliage ignites into flaming shades of yellow. The shrub seldom exceeds 6 feet tall and 3 to 4 feet wide. An easy-to-grow, multi-season shrub you will not regret planting...and the hummingbirds and butterflies will thank you for it!




Landscape & Garden Uses

Growing upright to about 5 to 6 feet tall and 3 to 4 feet wide, Ruby Spice Clethra is ideal for use as a specimen or in groupings in sunny to partially shaded landscape borders and around patios, decks and other outdoor living spaces where the fragrance, flowers and the hummingbirds and butterflies that visit can be enjoyed. Excellent in garden spots with moisture retentive soil, though adapts to somewhat drier soils. A fine addition to butterfly and hummingbird gardens, pink theme gardens, wildlife gardens, cottage gardens, and fragrance gardens.  

Suggested Spacing:  3 feet apart for solid hedges;  8 feet or more apart for space between plants




Cultural Preferences

Ruby Spice Clethra is very easy to grow and grows best in consistently moist, slightly acid soils in sun to part shade however tolerates a range of conditions including shade, wet soil, and salt spray. Exceptionally low maintenance requiring no pruning. Free of any pest and disease problems!
