Sander's Paphiopedilum is native to Borneo. Plants occur in northern Sarawak near the border with Brunei, at heights of 150-600 m. They often grow on vertical, south-facing limestone cliffs, in shady places, where only scattered morning light reaches. Paphiopedilum sanderianum usually grows on limestone rocks with roots embedded in moss and leaf litter, filling the fissures with which water drips. Sometimes they grow in the fork of trees, and their roots immerse in accumulated moss and fallen leaves.
Paphiopedilum sanderianum orchid, also called as Sander's Paphiopedilum, Cordula sanderiana, Cypripedium foerstermanni, Cypripedium sanderianum, Paphiopedilum sanderanum, is a species of the genus Paphiopedilum. This species was described by (Rchb. f.) Stein in 1895.

Sander's Paphiopedilum is native to Borneo. Plants occur in northern Sarawak near the border with Brunei, at heights of 150-600 m. They often grow on vertical, south-facing limestone cliffs, in shady places, where only scattered morning light reaches. Paphiopedilum sanderianum usually grows on limestone rocks with roots embedded in moss and leaf litter, filling the fissures with which water drips. Sometimes they grow in the fork of trees, and their roots immerse in accumulated moss and fallen leaves.
This Paphiopedilum species is a medium sized, hot to warm growing, lithophytic species that has 4 to 5, linear, shiny green leaves. The leaves are up to 45 cm long and 5 cm wide. They are bent or even drooping, have a clearly split apex, and the upper surface of the leaves is shiny and uniformly green. The underside has a pronounced bulge and has purple spots at the base.
This orchid blooms in the spring through winter on a suberect, terminal, purple, 2'' (60 cm) long, pubescent inflorescence with an elliptic-lanceolate, red brown, floral bract carrying 2 to 5, simultaneously opening flowers. The flowers are about 7 cm tall, not counting the exceptionally long petals of the inner whorl, which are usually about 60 cm in length, but there are reports about such 100 cm long. The dorsal petal is pale greenish-yellow with a purple margin and has about 10 brownish-purple stripes. It is covered with hairs, especially on the bulge and at the tip. The lower petal is similar in color and is also covered with hairs, but has narrower longitudinal stripes. The densely hairy petals of the inner whorl are pale yellowish-green with irregular brownish-purple dots and spots near the base, and become completely purple towards the apex. The yellowish-green lip has purple streaks. The base of the pollen chamber is yellow and densely covered with soft, thin hairs.
GROW AND CARE PAPHIOPEDILUM SANDERIANUM ORCHID
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:
This species needs a light level of 18000-25000 lux. Light need filtered or scattered and strong, constant air movement.
Temperature:
It is a thermophilic plant. The average day temperature is 28-29 ° C throughout the year and the average night temperature is 21-22 ° C, which gives a daily amplitude of 7-8 ° C.
Humidity:
Plant needs 80-85% of humidity throughout the year.
Substrate and growing media:
The substrate should be loose, permeable, which maintains moisture, but does not absorb. The addition of chopped sphagnum moss is preferred, especially when the plants are grown in places with low humidity. They are large plants and after a few years grow very much, their upper part becomes hard, so it is easier to deal with them, if they are planted in heavy, quite flat, ceramic pots with a wide base.
Watering:
Water is average to abundant throughout the year. The substrate of plants in cultivation should be constantly moist, and between subsequent waterings should only slightly dry out.
Fertilizer:
Plants should be fertilized every week or every two weeks with 1/10-1/4 of the recommended dose of fertilizer for orchids. The fertilizer with a high nitrogen content with fertilizer with an increased amount of phosphorus should be used alternately throughout the year.
Rest period and repotting:
This plants does not need a rest period but watering in winter can be somewhat reduced, especially in the case of plants cultivated in darker conditions of a short day in winter. These plants should never completely dry up.
Plants should be repotted before the substrate begins to decompose. Due to the need to maintain a constantly moist substrate, they generally have to be repotted every year, especially if the addition of moss to the substrate is large. Plants can be repotted at different times of the year, but it is best done in autumn or winter, which allows you to regain full form and root before summer heat.
