Dendrobium striolatum is endemic to eastern Australia. It often grows on rocks, boulders and cliffs from the Blue Mountains in New South Wales, through eastern Victoria to Tasmania, including Cape Barren Island and Flinders Island at elevations up to 1000 meters above sea level.
Dendrobium striolatum also called as The streaked rock orchid, Dockrillia striolata, Callista striolata, Callista teretifolia, Dendrobium milligani, Dendrobium striolatum var beckleri, Dendrobium teretifolium, Dockrillia striolata subsp. chrysantha, is a species of the genus Dendrobium. This species was described by Heinrich Gustav Reichenbach in 1857.
IDENTIFY DENDROBIUM STRIOLATUM ORCHID PLANT
Dendrobium striolatum is endemic to eastern Australia. It often grows on rocks, boulders and cliffs from the Blue Mountains in New South Wales, through eastern Victoria to Tasmania, including Cape Barren Island and Flinders Island at elevations up to 1000 meters above sea level.
It is a mini-miniature sized, warm to cold growing lithophyte with sympodial, pendulous, up to 600 mm long and 2 mm wide stems carrying a single, apical, terete, dorsally grooved, 40-120 mm long and 2-4 mm wide leaf.
The streaked rock orchid blooms in the spring with a 4 to 11 cm long, slender stemmed raceme with 1 to 2, non-resupinate fragrant flowers. The sepals and petals yellow, cream-coloured or greenish and have reddish streaks on the backs and on their bases at the front. Labellum about half as long as the sepals and recurved.
DENDROBIUM STRIOLATUM ORCHID PLANT CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Dendrobium striolatum like plenty of light (25000-50000 lux, better in bright, diffused light) but not direct sun's rays, except in the early morning. The light level should be as high as possible, which the plant can tolerate without scalding the leaves.
Temperature:
The average temperature of the summer day is 24-25 ° C, night 20 ° C, giving a daily difference of 4-5 ° C. In winter the average day temperature is 11-14 ° C, night 7-10 ° C, giving a daily difference of 4-5 ° C.
Humidity:
For most of the year, The streaked rock orchid need the humidity of almost 80%, but at the end of winter and at the beginning of spring it drops to around 60%. Too dry air has a negative effect on the development of the plant: its growth is inhibited, and the leaves begin to turn yellow and dry out. The higher temperature, the higher the humidity should be, and the higher the humidity, the more often and longer it is necessary to ventilate the room where the plants are contained, otherwise the probability of rotting and various kinds of fungal diseases.
Substrate, growing media and repotting:
Dendrobium striolatum grows best on rafts that are formed by nailing (with copper nails) a number of short lengths of beech or hardwood horizontally across a similar number of perpendicular pieces to form a sort of lattice or grating. The raft is covered with fibre or peat with a little green sphagnum moss, the orchid being fastened thereon with copper wire.
They can also grows on blocks which are pieces of hardwood of suitable length and width (usually about 12 inches by 5 inches is satisfactory), or of palmwood or tree fern trunk, to which the plant is bound with copper wire. When hardwood is used, a little fibre should be fastened to the surface to make it easy for the young roots to obtain a grip. Where tree fern is used, the basal part of the trunk, which is covered with thick, fibrous growth, should be used. Where the roots of the orchid are scanty or weak, a little sphagnum between the plant and the block will encourage quick root growth. Where the roots are plentiful and vigorous, however, this is not necessary.
Watering:
The streaked rock orchid will need heavy watering from the commencement of Summer until the first chill spell of Autumn, when watering should practically cease until the new shoots appear in Spring.
Watering is directly dependent on the temperature of the content, the higher it is, the more often it needs to be watered. When watering, excess water should flow freely from the pot, since stagnation of water both inside the pot and in its pan can very quickly lead to rotting of the roots and the lower part of the plant.
Fertilizer:
It is recommended to use a 1/4-1/2 dose of orchid fertilizer weekly. You can use the balanced fertilizer throughout the year or from spring to mid-summer use high-nitrogen fertilizer, and then until the end of autumn high-phosphoric fertilizer to stimulate flowering.
Rest period:
Dendrobium striolatum need less water in the winter, especially if they grow under the conditions of a dark, short day that occurs at moderate latitudes. They should dry somewhat between waterings, but they should not be dry for a longer period. Frequent morning fogging and rare, economical watering should allow the plant to go through a dry period of rest, while providing it with sufficient humidity. Fertilization should be reduced or eliminated until new growths appear and a more abundant spring watering begins.
