A sport of 'Pink Spires', 'Ruby Spice' is considered perhaps the finest truly pink Summersweet. It has 4 to 5 inch spikes of good, bright rose-pink fragrant flowers for a month or more in mid-summer. It has a dense suckering habit growing to 8 feet by 6 feet and prefers sun or part shade and moisture. (Sunlight Gardens)

This cultivar was selected from a branch sport of 'Pink Spire' in 1992 and has slightly darker more rose-colored flowers that show the color more throughout the petals and tends to hold its color a little longer.

The summer blooms of Ruby Spice Clethra attract all sorts of pollinators, from bumble bees to wasps, all of which flock to the sweetly scented flower spikes. Clethra grows well in either sun or shade, but it seems to need more water in a sunnier location.
