Ludisia discolor (Ker Gawl.) Blume (1859);基名 Goodyera discolor Ker Gawl.(1818年發表,依栽培植株描述,而非野外採集的開花標本)。
俗名
Jewel Orchid(寶石蘭/血葉蘭),因絲絨狀暗色葉片與紅銅色葉脈而得名;中文慣稱血葉蘭。
分類地位
血葉蘭屬現時被接受的物種共2種——本種與2013年才發表的菲律賓新種 L. ravanii,在此之前長期被視為單種屬。市售的「var. alba」「nigrescens」「Super Veination」等名稱均非正式接受的植物學變種,屬園藝選育品系/商業名稱,POWO並未列出本種任何接受的種下分類單元。
一種早早就因葉片而非花朵受矚目的蘭花: 1818年發表本種時,依據的是一株栽培於溫室的植株,而非野外採集的開花標本——當時刊登這份描述的期刊本就以英國園藝栽培植物的彩色圖譜為主,用栽培株描述並不罕見。1859年布魯姆(Blume)將牠移入新建的血葉蘭屬。市售的「alba」「nigrescens」「Super Veination」等名稱都只是園藝選育或商業命名,並非正式的植物學變種——POWO並未列出本種任何接受的種下分類單元;本屬直到2013年才多了第二個接受種,菲律賓的 L. ravanii,在此之前長期被視為單種屬。
花朵小小的,蕊帽卻是亮黃色: 栽培者有時將本種與相近的金線蓮屬(Anoectochilus)雜交,店內的「紅絲絨葉寶石蘭」正是血葉蘭 var. nigrescens 與暹羅金線蓮(Anoectochilus siamensis)配出的屬間雜交後代(屬間雜交統稱 ×Ludochilus)。野生族群的授粉生態目前查無嚴謹的田野觀察記錄,現有資料多來自栽培株的觀察,並非野外直接證據。另一個常見的誤會:許多人以為那一點亮黃色是唇瓣的顏色,實際上唇瓣是白色,亮黃色的是蕊柱頂端的蕊帽(anther cap)。
殺死血葉蘭最快的方法,是對牠太好: 比起多數附生型蘭花怕乾燥,依多數栽培者經驗,血葉蘭的常見死因反而是澆水過度、讓莖基部長期泡在積水中引發爛心——這與「蘭花都怕旱」的既定印象恰好相反。至於牠是否真的有香氣,部分資料(如新加坡National Parks Board)記為有香,但栽培者之間回報不一,本文不做定論。

An orchid you grow for its leaves, not its flowers — and one that breaks nearly every rule about what orchids are supposed to need.
An Unusual Orchid, Named for the Wrong Reason
Ludisia discolor got its first description in 1818 from a plant growing in a European stove-house rather than a wild-collected specimen — not unusual for the journal that published it, which specialized in colour plates of plants already in cultivation. Blume later moved it into its own genus, Ludisia, in 1859. It's a plant that has long been sold for its velvet, near-black leaves and copper-red veining rather than for anything happening at bloom time.
A Forest-Floor Plant, Not a Tree-Dweller
Unlike most orchids people grow — epiphytes clinging to tree bark — this one lives on the ground, creeping through damp, shaded leaf litter in evergreen broad-leaved forest valleys across a wide swath of southern China and Southeast Asia, roughly 900–1,300 m per Flora of China. That terrestrial, forest-floor habit explains almost everything about how it wants to be grown: moist, humid, shaded, and never baked by direct sun.
Light: The Orchid That Wants Less of It
Give it low to medium indirect light, not the bright conditions most orchids crave. Too much sun scorches and washes out the dark, velvety leaf colour that's the entire point of growing the plant. This tolerance for shade is exactly why it does well as an indoor foliage plant and a terrarium subject, thriving in corners too dim for almost anything else people try to grow.
Temperature: No Winter Performance Required
Keep it warm all year, roughly 15–28°C, with no deliberate cool-down or dormancy period. That's a real departure from many terrestrial orchids from temperate climates, which need a winter rest to flower or even survive — and it's probably the single most common misunderstanding newer growers bring to this plant.
Media and Water: Moist, Airy, Never Standing
A moisture-retentive but still airy mix works best — sphagnum, fine bark, perlite and charcoal in combination, or a ready-made terrestrial orchid blend. Keep it evenly moist; this isn't a plant that wants to dry out between waterings the way many epiphytic orchids do. What it really can't tolerate is water sitting at the base of the stem — that's the direct path to crown rot, and by most accounts the leading cause of death in cultivation, well ahead of underwatering.
Feeding and Flowering
Light, dilute feeding through active growth is all it needs. Wild populations typically flower February–April per Flora of China, though timing is more variable in cultivation and often overlooked entirely — the blooms are small, short-lived and white, with a twisted lip and column, pleasant but genuinely secondary to the foliage display.
A Case of Mistaken Identity
Look closely at an open flower and the bright yellow spot that catches the eye isn't the lip — it's the anther cap at the tip of the column; the lip itself is white. It's a small detail, but one that trips up a lot of casual descriptions of the flower.
Crossed With Its Relatives
Growers also cross it with the closely related jewel-orchid genus Anoectochilus; the intergeneric result sold here as 'Red Velvet' is one example, pairing L. discolor var. nigrescens with Anoectochilus siamensis. Wild pollination biology, by contrast, is thin on documentation — what exists comes mostly from cultivated plants rather than confirmed field observation.
Why It's Worth Growing
It asks for less light and less fuss than almost any other orchid, propagates readily from a simple stem cutting, and rewards a dim windowsill or terrarium with foliage colour most houseplants can't match. For anyone put off by orchids that demand bright light and a fussy watering schedule, this is the counter-example.
栽培者也會把牠與近緣的金線蓮屬(Anoectochilus)配種,店內的「紅絲絨葉寶石蘭」正是血葉蘭 var. nigrescens 與暹羅金線蓮配出的屬間雜交例子,而野生族群的授粉生態目前仍缺乏嚴謹的田野觀察紀錄。整體而言,牠對光照與澆水的要求都遠比多數蘭花寬容,又能輕易用莖段扦插繁殖,適合放在陰暗窗邊或生態瓶中,用葉色彌補多數室內植物做不到的視覺效果——對於被「高光照、嚴苛澆水」嚇退過的人來說,血葉蘭正是最好的反例。

🌎 Plant Data
Scientific Name
Ludisia discolor (Ker Gawl.) Blume (1859); basionym Goodyera discolor Ker Gawl. (1818), described from a cultivated plant rather than a wild-collected flowering specimen.
Common Names
Jewel Orchid, for its velvety dark leaves with coppery-red veins; the Chinese common name is 血葉蘭 (xuè yè lán, "blood-leaf orchid").
Taxonomy
The genus Ludisia currently holds 2 accepted species — this one and the Philippine L. ravanii, described in 2013; before that the genus was treated as monotypic. Trade names such as "var. alba", "nigrescens" and "Super Veination" are not accepted botanical varieties — they're horticultural selections; POWO lists no accepted infraspecific taxa for this species.
Native Range
Southern China (Guangdong, Guangxi, Hainan, S.–SE. Yunnan), Myanmar, Thailand, Laos, Cambodia, Vietnam, the Malay Peninsula, Sumatra, Borneo and the Philippines.
Habitat
Damp valley-floor leaf litter in evergreen broad-leaved forest (per Flora of China).
Elevation
Roughly 900–1,300 m (per Flora of China).
Growth Habit
Terrestrial, creeping rhizomatous stems; an evergreen foliage orchid with no true leafless rest period.
Mature Size
Trailing to semi-upright stems to 15–30+ cm; grown mainly for the foliage rather than the flowers.
Bloom Season & Scent
Wild populations typically flower February–April (per Flora of China); timing is more variable in cultivation. Flowers are small, short-lived and white, with a twisted lip and column, not especially showy. Some references (e.g. Singapore's National Parks Board) describe it as fragrant; grower reports vary, so this guide doesn't call it either way.
💧 Care Data
Difficulty
Low — one of the easier orchids to keep, and a common entry point into "foliage" orchids, but intolerant of a soggy, stagnant base.
Light
Low to medium, no direct sun — unusually shade-tolerant for an orchid. Too much light scorches and bleaches the velvety leaves; it does well under indoor indirect light or grow lights, which is part of why it's popular for dim corners and terrariums.
Temperature
Warm year-round, roughly 15–28°C. No deliberate winter cool-down is needed — unlike many temperate terrestrial orchids, and probably the single most misunderstood point about this plant. Damage can occur below about 10°C.

Source: climate normals for Đà Lạt, Lâm Đồng Province, Vietnam (Địa chí Đà Lạt plus Vietnam Institute for Building Science and Technology records), adjusted from Đà Lạt's actual elevation of ~1,500 m down to ~1,000 m — within this species' 900–1,300 m elevation range per Flora of China — at the standard lapse rate of 0.6°C per 100 m. Not an on-site measurement; for cross-reference only.
Humidity
On the higher side, ideally 60–80%+; typical indoor humidity plus occasional misting is usually enough.
Media
Moisture-retentive but still airy and free-draining — a mix of sphagnum moss, fine bark, perlite and charcoal is common, or a ready-made terrestrial-orchid blend.
Watering
Keep evenly moist and never let the mix dry out completely, but avoid letting water stand at the base of the stem — by most accounts, overwatering and crown rot, not drought, is the most common way to lose this plant.
Fertilizing
Light, dilute orchid fertilizer applied regularly through active growth; no need for a strong formula.
Propagation
Easy by stem cuttings — unusually easy among orchids. A healthy cutting rooted in moist media, or a division, generally takes without much fuss.
💡 Did You Know
Described from a greenhouse plant, not a wild specimen: The 1818 description of this species was based on a plant grown under glass rather than a wild-collected flowering specimen — the journal that published it specialized in colour plates of exotic plants cultivated in British gardens, so that wasn't unusual for its time. Blume moved it into the newly created genus Ludisia in 1859. Trade names like "alba", "nigrescens" and "Super Veination" are horticultural selections or marketing names, not formal botanical varieties — POWO lists no accepted infraspecific taxa for this species. The genus itself only gained a second accepted species in 2013, the Philippine L. ravanii; before that it was treated as monotypic.
Small flowers, a surprisingly bright yellow cap: In cultivation, this species is sometimes crossed with the closely related jewel-orchid genus Anoectochilus; our own 'Red Velvet' is exactly such a cross, between L. discolor var. nigrescens and Anoectochilus siamensis. Wild pollination has not been rigorously documented in the field — what's on record comes mostly from observations of cultivated plants, not confirmed wild pollinator visits. A common mix-up: that bright yellow spot is often assumed to be the lip, but the lip is white — the yellow belongs to the anther cap at the tip of the column.
The fastest way to kill it is to love it too much: Unlike most epiphytic orchids, which fear drying out, this species' most commonly reported cause of death, by most growers' accounts, is the opposite: overwatering, with standing water at the base of the stem rotting the crown. On fragrance, some references (including Singapore's National Parks Board) describe it as scented, but grower reports vary enough that this guide doesn't call it either way.

It's unfortunate the other reviewer didn't have luck with his utricularia order. Perhaps it was mostly a case of mistaken expectations as the plants were sold/described as as bare root "as-is" grade C, (recommended for experienced growers). I have received many utricularia from various Orchidmart pre-orders and they are all doing great including U. Praelonga. Admittedly some pots were rougher than others but none were dead or past salvaging. I will continue to purchase carnivorous plants from Orchidmart as the variety and prices can't be beat.
I was worried about the shipment in cold winter, but plants arrive safely with nursery pot, heated pad , good packaging. Healthy plants, can’t wait to see the new roots after settle in
