Paphiopedilum henryanum is a compact slipper orchid native to limestone cliffs in Guangxi and Yunnan in China and northern Vietnam. Its narrow, glossy dark-green leaves form a neat rosette, and from autumn into winter it sends up a flower stem of roughly 12-15cm topped with a single bloom about 4-6cm across. Rather than bold colors, the appeal lies in the contrast between the tidy foliage and that single, understated flower, making it a favorite among more experienced orchid growers. It calls for intermediate-level care, but rewards patient growers who divide and replant it over the years. Every Paphiopedilum species is listed in CITES Appendix I, which makes it an Internationally Endangered Species under Japan's Act on Conservation of Endangered Species (種の保存法). Transferring a plant within Japan, whether by sale or gift, requires a registration certificate under that Act, and this applies to plants propagated in Japan too. When buying, always confirm that the plant comes with its registration certificate.

About Henry's Paphiopedilum

7 things to know before growing Henry's Paphiopedilum
1Avoid Direct Sun
Coming from limestone cliff habitats, this orchid likes bright conditions but strong midsummer sun can scorch the leaves. A sheer-curtained window or bright, well-ventilated partial shade works best.
2Water When Dry
Water thoroughly once the surface of the mix has dried out, rather than keeping it constantly damp. Make sure water drains freely from the pot, since standing moisture around the base can lead to rot.
3Use Free-Draining Mix
Because it grows on rocky limestone ledges in the wild, this plant prefers a mix that lets its roots dry out between waterings. A bark-and-perlite based compact mix formulated for Paphiopedilum suits it well.
4Repot and Divide After Flowering
Repot once the mix starts to break down, timing it for after flowering has finished. This is also the best moment to divide the plant, producing new offsets with minimal stress.
5Keep Routine Steady in Bloom Season
While the flower stem develops from autumn into winter, avoid major changes to light or watering habits. Keep it away from cold drafts too, since low temperatures at this stage can damage the developing bud.
6Choose Healthy-Leaved Plants
Glossy, deep-green leaves are the sign of a healthy plant. Avoid specimens with dried leaf tips or blackened bases. As an Appendix I species, it must come with a registration certificate under Japan's Act on Conservation of Endangered Species (種の保存法), so always confirm the certificate when acquiring one.
7A Slow, Long-Term Orchid
This is considered an intermediate-level orchid, and flowering may take a while to become reliable until conditions suit it. It's best approached as a plant to grow patiently over years, propagated through repeated divisions.
