Gardeners' Notes:

Positive Nobody On Jul 21, 2003, Nobody from Frankfort, KY wrote:

They can be grown in as north as North Carolina, etc., but it depends on the locality of plant. Calanthe discolor can be found in Hokkaido, and the climate there is about zone 5 or 6. I would say it's safe to grow in zone 7 or 8.

There is a wide range in flower color, and this is the basis of many natural (e.g., C. x bicolor) and artificial hybrids (C. Kouzu, etc.).

Neutral Baa On Aug 31, 2001, Baa wrote:

Not fully hardy but can be grown outside in sheltered areas. Prefers a well drained, humus rich soil in partial shade.
