The Vanda merrillii var. rotorii is a botanical orchid rarely found outside of specialized collections. Originating from the Philippines, this subtle variety of the Vanda merrillii is notable for its graceful flowers, compact growth and pronounced aerial root system. A fascinating species for those looking for something special.
Origin
Vanda merrillii var. rotorii is native to the island of Luzon, in the northern Philippines. It grows there epiphytically in limestone-rich forests at low elevations, where humidity is high and light falls filtered through the canopy. The addition "rotorii" refers to a local botanical collector to whom this rare variety is dedicated.
Characteristics
This variety remains relatively compact, with short foliage and firm, leathery leaves. Flowers usually appear in clusters of 3 to 7 at a time and are whitish to pale yellow in color, with a characteristic yellow to orange-red lip that can be strongly fragrant, especially in the morning. Compared to the common merrillii, the flowers are slightly more finely built and appear more refined. The plant develops a dense network of aerial roots that help absorb moisture and nutrients from the air.
Care
Light
Give this Vanda plenty of bright, indirect light. Direct sunlight in the morning or late afternoon is well tolerated, as long as it does not burn the leaves.
Temperature
A daytime temperature between 24 and 30°C is ideal, with nighttime temperatures around 18°C.
Substrate
This species is best raised in a wooden Vanda basket without substrate, allowing aerial roots to grow freely.
Humidity
High humidity of at least 60% is important. At lower humidity, daily misting can help.
Nutrition
Feed weekly with a balanced orchid fertilizer at a low concentration (¼ of the recommended dose) interspersed with rinses with demineralized water.
Watering.
Spray daily or dip 2 to 3 times a week with lukewarm, demineralized water. In warm periods, this may be increased.
Flowering
Flowering usually takes place in the dry season (in Europe often in the fall or spring), and may recur several times a year if properly cared for. Flowers last about two weeks and are especially fragrant early in the day.
