‘Ruby Clusters’ is a wonderful bloomer
with showy clusters of tubular crimson red
flowers. After flowering, reddish-purple berries
appear adorning the arching stems with a backdrop
of dark green foliage. Prune after flowering
as the blooms form on the tips of the stems that
grow during the summer. Sensitive to shortened
day length, ‘Ruby Clusters’ comes into bloom in
fall and flowers for us fall, winter and spring. It
puts on a sensational floral show when color is
needed the most. This Cestrum doesn’t mind it
cool as we grow it in a greenhouse that has night
temperatures in the 40’s.
