§They are monopodials which mean they have a single, continuously lengthening main stem.
§The tall ones will need staking as they climb using aerial roots
§The leaves are varied from strap and deeply grooved to almost cylindrical which is called terete. In between is called semi-terete.
§They grow well outside in Brisbane and they love air movement, particularly around their roots.
§Are Epiphytic therefore love growing on trees.
§Can be grown in pots or wooden slatted baskets (if and when they are small)
§Some like the terete leaved ones will take full sun
§Their root system is very adventurous therefore no medium need be used.
§They will produce side shoots when mature
§Because they do not have pseudo bulbs they need constant moisture during the warmer months.
§Love humidity, so growing near water or damping down around them is important.
§Some are tropical plants and therefore do not like temperatures lower than 15 degrees Celsius in winter.
§The flowers are produced on racemes or spikes which originate from the main stems.

·Use a pot or basket that will just accommodate their roots
·Terracotta pots or wooden slatted hanging baskets are best
·There is no need to use any potting medium
·Plants will need to be misted daily during warmer months
·They can be grown in the garden on a raised bed of rocks, crocks and logs
·They are propagated by stem cuttings below an aerial root once the plant has reached a good height ( approx. one metre)
·They can also develop side shoots which can be removed once they have attained a good size.
·Cut the stem with a sharp knife on a slant.
·The Dendrobium beetle loves the flowers of the Vandas and a daily check is needed in the warmer months.
