Dendrobium speciosum var. capricornum is the most northerly variety of Dendrobium speciosum, and least common in cultivation in the USA. Our plant is similar in size to the var. pedunculatum of this species, which short, compact canes. Due to its northerly range, we bring it inside for the winter with our other Queensland dendrobiums, with a minimum night temperature of 50F (10C). Our other varieties of Dendrobium speciosum, except var. penduculatum, winter outside all year, tolerant of the upper 20s (-3C) in a sheltered location near the house.
