Calanthe sieboldii is probably the most spectacular species of all Japanese terrestrial orchids. This perennial orchid produces at the end of spring a cluster of large pale yellow flowers with bright lemon, sometimes spotted with brown at the level of the lip, more or less perfumed according to the plants.
It is also characterized by a very long bloom for a perennial orchid.

The Calanthe genus contains about 200 species, mainly in the Far East. This is a very popular orchid family in Japan, where they are considered sacred flowers. The variety of colours seems infinite. Some species and cultivars have a very pleasant scent. As the flowering period is the longest of all perennial orchids, this plant is also an excellent choice for growing in a pot on a terrace. In this case, be sure to select a large enough pot (minimum diameter 30-40 cm) so as not to hinder the development of new shoots that will appear on the periphery the following year.
Calanthe Orchids like protected environments, humus-rich, light, fresh and regularly humid soils.
Plant the Calanthe orchids in a protected spot, in clear and humid undergrowth, or even near water points, close to Cypripedium, arisaemas, ferns or hostas.
The soil should never dry up in summer, and it should never be waterlogged in winter. Make sure to water regularly between April and September.
Terrestrial Calanthe Orchids are quite greedy plants during the growing season: a regular supply of geranium-type fertilizer at 1/2 dose from mid-May to mid-September will be very beneficial.
Calanthe Orchids can withstand a minimum temperature of -10°C to -15°C. It is advisable, at least in regions with severe winters, to protect them during long periods of freezing (temperatures below -10°C for a long period).
No protection is required outside these periods.
Plant them in the semi-shade, at the edge of large trees.
As the seasons go by ...
During the winter, the plant persists in the form of a pseudo-bulb.
Young Calanthe orchid shoots appear and spread their leaves in April. Depending on the species, flowering appears in spring, summer or autumn.
Over the years and successive cycles of growth and dormancy, Calanthe Orchids not only grow stronger, they also multiply thanks to the annual appearance of new shoots.
