‘Ruby Spice’ Sweet pepperbush: Thriving Native for Maryland Piedmont
LGS Notes: ‘Ruby Spice’ sweet pepperbush, also known as summersweet, is a more colorful version of the straight species and the ‘Hummingbird’ cultivar. The clusters of flowers are pink, and still attractive to bees and butterflies. It can also be used in rain gardens and native landscapes in a large range of sun exposure. This plant is pretty tough once established, though deer will munch it if they are hungry and it’s convenient. Give clethra lots of space in your garden if you go with the straight species. ‘Hummingbird’ is a more compact variety and ‘Einstein’ is even more compact but harder to find. ‘Sixteen Candles’ is a medium height variety with white flowers. I like to combine Ruby Spice with Blue Marvel salvia, white or pink turtlehead, inkberry holly and coastal leucothoe (for evergreen).
