Cultivation Details
The climate of Ulleung Island on which Dystaenia takeshimana grows is classified as humid subtropical with average monthly temperatures ranging from 4.4 - 26.9°c throughout the year, and lows that can occasionally fall as low as -13°c. Mean annual precipitation is 1,480mm, spread throughout the year but with the wettest months in Summer and much of the precipitation in winter falling as snow. Succeeds in full sun or in partial shade.
Propagation
Seed - sow in winter or early spring. The seeds need 3 - 4 weeks cold stratification. Once stratified, seedlings should start to appear in about 4 weeks. Another report does not use cold stratification, but looks at improding water uptake of the seed. It says that the seed, and the wings surrounding it, are waxy and repel moisture. Removing the wings speeds up imbibition, even more so if the seed is also treated with Potassium hydroxide for 5 hours (you need to know what you are doing here, because it would be very easy to kill the seed). Seeds with their wings removed and then soaked in water for 4 days produced more then 85% germination. Pregermination temperature treatment at 40°c for 8 days, reduced the time for seeds to germinate and also increased germination rates significantly.
