IDENTIFY DENDROBIUM VEXILLARIUS
Dendrobium vexillarius is native to New Guinea, New Ireland and Moluccas Islands. These plants grow on the tops of horizontal branches of trees in rain forests, mountain forests, shrubs and meadows. At high altitudes, they usually grow epiphytically on the surface of the ground in deep layers of peat, humus and mosses. They usually grow at heights of 2000-3500 m, but some varieties occur at heights of just 1100 m.
It is a small sized, cool to cold epiphyte, which reaching 13-25 cm in height, with cylindrical, light green, 13-25 cm long stems carrying 2 to 5 apical, pointed, dark green on top, gray green below, 5-15 cm long leaves.
The Flag-Carrying Dendrobium blooms at most any time of the year on an erect, short, few to several flowered raceme that arises from the nodes of leafed and leafless canes with 2 to 7, shiny, color variable flowers that can last for months. The flowers are 2.2-5.0 cm long. They have ovoid to oval-elliptical dorsal petal, ovoid-triangular lateral outer petals and slightly oval petals of inner whorl. The lip is almost oblong, has a curved top edge and small, rounded side plots.
The color of the flowers is very variable and depends on the variety: Dendrobium vexillarius var. albiviride (The petals of both whorls are pale greenish-white to pale yellow and the lip is green with an orange tip), Dendrobium vexillarius var. elworthyi (The petals of both whorls are orange to reddish-orange and the dark lip may be purple to almost black with an orange tip), Dendrobium vexillarius var. microblepharum (The petals of both whorls are orange, orange-red or orange-yellow), Dendrobium vexillarius var. retroflexum (The petals of both whorls are greenish-blue, blue, bluish-gray or gray, often tinted violet and the lip is dark purple, almost black, with a dark orange-red top), Dendrobium vexillarius var. uncinatum (The petals of both whorls are usually pinkish-purple, but some clones are pale yellow, orange, carmine, crimson, purple-red or blue and the lip is dark, with a dark pinkish-red top. Those that grow in full sun have more bright colors), Dendrobium vexillarius var. vexillarius (The flowers are yellow to greenish-yellow).
DENDROBIUM VEXILLARIUS 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 vexillarius needs a light level of 20000-30000 lux.
Temperature:
The average temperature of the day throughout the year is 20-24 ° C, night 8-10 ° C, giving a daily difference of 10-15 ° C.
Humidity:
The Flag-Carrying Dendrobium needs the humidity throughout the year of probably 80%.
Substrate, growing media and repotting:
Dendrobium vexillarius can be mounted on tree rootstocks or cork, with high humidity ensured and watering is carried out at least once a day in summer. When growing in pots, any loose, quickly drying substrate is recommended. Repotting can be done when new roots grow.
Watering:
Precipitation is abundant throughout the year, but during 3-4 winter months there are fewer of them. The cultivated plants should be kept constantly moist.
Fertilizer:
It is recommended to apply weekly or every two weeks 1/4-1/2 doses of balanced fertilizer to orchids throughout the year.
Rest period:
Watering and fertilizing should be slightly reduced in winter, especially for Dendrobium vexillarius grown in dark and short days at moderate latitudes. The plants should dry out slightly between waterings, but they can never completely dry out. When the spring starts, watering and fertilization should gradually increase.
