Dendrobium secundum nicknamed the toothbrush orchid because of the flower arrangement along the top of the raceme. is a widespread species from Thailand, Burma, Cambodia, Laos, Sumatra, Borneo, Java, Sulawesi (Celebes), and many smaller Indonesian islands and Vietnam to list a few.
Psudobulbs are described as growing up to 50 odd cm's although we have a much bigger plant than this.
Typically flowers are formed on last years growth after it drops leaves in Winter.
Once plants get big enough they may flower many times in the second half of the year but only ever on old canes.
Ideal conditions are
- medium to high light that is filtered,
- cool to hot locations
- in a well drained mix that dries before it is watered again.
They can be grown on a mount or on trees.
