Rothschild’s slipper orchid is a Paphiopedilum species from a single mountain in Borneo. Paphiopedilum rothschildianum grows wild only on Mount Kinabalu in Sabah, Malaysia. Growers also call it the gold of Kinabalu orchid, the Kinabalu orchid, or the queen’s orchid.
It ranks among the most sought after slipper orchids in cultivation. Its size, its history, and its price legend all feed that reputation. Where it grows, how it earned its name, and how to grow one at home all follow below.
Where Rothschild’s Slipper Orchid Grows on Mount Kinabalu
This species grows on the slopes of Mount Kinabalu, at 500 to 1,200 meters elevation. The soil there is serpentine, a mineral rich rock type that few plants tolerate. Kew Science lists Borneo, specifically Sabah, as its only native range.
Plants root in shallow pockets of leaf litter over rock, often on steep, well drained slopes. Rainfall is heavy and humidity stays high through most of the year. Shade from surrounding forest keeps the roots cool even as daytime air warms.
The flowers are the plant’s signature feature. The two lower petals hang down and twist, spanning up to 12 inches across in mature plants. Each stem can carry up to six blooms, which is unusual for a Paphiopedilum.
The species belongs to the wider paphiopedilum orchid group, though its size and petal span set it apart. For basic genus care that applies across the family, see our paphiopedilum orchid guide.
Discovery and the Rothschild Name
British botanists collected the species on Kinabalu in the late 1800s. It reached cultivation around 1887 and 1888, and was named for the Rothschild banking family. The family funded major plant collecting expeditions of that era, a common practice among wealthy Victorian plant collectors.
The species was later feared extinct in the wild, as collectors stripped accessible populations from the mountain. Botanists rediscovered surviving populations decades afterward, which renewed interest in its conservation. Today it sits alongside other rare species in our rarest orchids in the world roundup.
How It Differs From Other Paphiopedilum Species
Paphiopedilum species fall into rough groups by leaf type and temperature preference. Rothschild’s slipper orchid is a strap leaf, multifloral type, related to species like Paphiopedilum sanderianum. Multifloral and mottled leaf types generally prefer warmer conditions than the plain green leaf species.
That distinction matters for a mixed collection. Green leaf Paphiopedilum species tolerate cooler nights and often sit with Cattleya or Phalaenopsis. Rothschildianum and its warmer growing relatives usually need their own, slightly warmer spot.
The Price Legend, and What Rothschild’s Slipper Orchid Actually Costs
Stories about rothschild’s slipper orchid selling for enormous sums have circulated for decades. Historic sales did reach into the thousands of dollars for exceptional, blooming size specimens. Those prices reflected scarcity and slow propagation, not typical retail cost.
Wild collection and poaching pushed the species toward CITES Appendix I status. That listing bans international trade in wild collected plants across every member country. Legally propagated, nursery grown seedlings cost far less than the price legend suggests.
Size still drives price within nursery grown stock. A young seedling costs little, while a near blooming size division costs considerably more. For a broader look at what drives orchid pricing, read our guide on how much do orchids cost.
Why the Bloom Takes So Long
Patience is part of growing this species. Seedlings often take 10 to 15 years to reach blooming size from seed. That slow growth is one reason mature specimens command higher prices than most orchids.
Breeders pollinate flowers by hand to produce seed pods, since natural pollinators rarely reach cultivated plants. Learn more about how growers control this process in our guide to orchid pollination. Even after pollination succeeds, the resulting seedlings still need years of steady growth before their first bloom.
Buying an established division shortens the wait considerably. A division with three to five growths can flower within a season or two of settling in. That head start is one reason divisions cost more than fresh seedlings.
Rothschild’s Slipper Orchid Care for Home Growers
This species prefers intermediate temperatures, unlike some warmer growing Paphiopedilum types. Nights between 55 F and 72 F suit it well, with days from 70 F to 85 F. Bright shade works better than direct sun, with 2 to 3 hours of gentle daily light.
Pot rothschildianum in a coarse, well drained mix. Many growers add limestone chips or perlite, since the species grows on mineral rich soil in the wild. Keep the mix evenly moist, never soggy and never bone dry.
Feed at quarter strength with regular waterings, using a balanced fertilizer. Flush the pot monthly or quarterly with distilled or rain water to clear built up fertilizer salts. Humidity of 40 to 50 percent keeps growth steady through the year.
Repot about every two years, or sooner while the plant is still a small seedling. When dividing a mature clump, keep groups of three to five growths together. Bury the root and stem junction about half an inch deep at the center of the new pot.
Rothschild’s slipper orchid shares its basic needs with other slipper types, but runs warmer than green leaf Paphiopedilum species. For general slipper orchid habits, see our lady slipper orchids page. Our lady slipper orchid care guide covers watering and light in more depth.
Common Mistakes Growers Make With This Species
Many general orchid guides treat every Paphiopedilum the same way. That advice misses the warmer temperature this species needs compared to green leaf types. Cool nights meant for a green leaf Paphiopedilum can stall growth on a rothschildianum.
Overfeeding is another common error. Full strength fertilizer burns the fine roots of this species faster than it helps growth. A quarter strength dose, applied consistently, works better than an occasional strong feeding.
Watering on a fixed schedule is a third common mistake. Check the mix before watering, since pot size and season change how fast it dries. Water again only when the top layer starts to feel dry, not on a strict calendar.
Famous Hybrids Bred From This Species
Breeders have used rothschildianum to create some of the best known Paphiopedilum hybrids. Paphiopedilum Saint Swithin crosses it with Paphiopedilum philippinense for dramatic, wide spread petals. Paphiopedilum Lady Isabel and Paphiopedilum Prince Edward of York also carry its genes.
These hybrids often bloom faster and grow more forgiving than the species itself. They stay popular at orchid shows for their striking flower shape. Many nurseries sell hybrid divisions well before pure species plants reach blooming size.
Buying Rothschild’s Slipper Orchid Legally
Always buy from a licensed nursery that propagates plants from seed or division. Reputable sellers can show CITES paperwork for the species on request. Wild collected plants are illegal to import or sell under international law.
A legitimate nursery grown rothschild’s slipper orchid seedling costs far less than the price legend implies. It also grows better, since nursery stock is already used to cultivated conditions. Avoid any seller who cannot explain where the plant, or its parent stock, came from.
