It occurs along the Great Dividing Range in south east Queensland, as a lithophyte.
D. x delicatum is primarily a lithophyte (growing on rocks). It is variable in habit, which is to be expected as its parents are also variable in habit.
The pseudobulbs can be up 20 to 35 cm long, thickest near the base and tapering towards the apex. There are usually 2 to 5 thick leaves at the top of each pseudobulb, the leaves being 75 to 175 mm long. The bulbs and leaves are very thick and are resistant to pest. The plant has a lovely profile and looks great in a terra cotta pot.
Flowers occur on 250 mm long stems in clusters of up to 14 or more flowers. They are usually pure white to cream with purple dots on the labellum and are usually long lasting and sweetly scented. Flowers are seen from late winter to spring.
Any free draining compost will do for this plant, which is not really fussy. It is a fast grower and prolific bloomer.
Temperature.
D x delicatum is very well suited to outdoor cultivation in temperate regions, with frost protection in a greenhouse or conservatory during the winter. It should not be grown in dense shade or flowering will be discouraged.
Watering can be done freely during spring, summer and autumn and should be kept to a minimum during winter.
