The flowers of this Dendrobium speciosum var. pedunculatum were like glowering lights to photograph. Some orchids “catch the light” with little effort when I’m creating orchid portraits, and this is surely one of them. It must be the inner glow.
Dendrobium speciosum is native to Australia and the peduculatum variety is one of the most northerly growing, found in Queensland to the south of the capricornum variety. Similar to variety capricornum, the pedunculatum variety of Dendrobium speciosum has relatively short, stocky pseudobulbs. This particular plant, which is 15-20 years old in a 8″ pot, has 14 pseudobulbs that are 6-8″ (15-20cm) tall. The flower spikes, however, are “full-size” for Dendrobium speciosum, about 24″ (60cm) in length.
We grow this variety outside until temperatures drop below 40F (4C) at night. It winters in the cool room (50F, 10C nights) from December-March, and flowers in mid to late winter.
