How does one successfully germinate Solanum dulcamara seeds (Bittersweet, Woody nightshade)?
Cambridgeshire, United Kingdom
Have tried chilling, soaking, and chilling and soaking before sowing. Have tried germination at 5, 18 and 22 degrees C., covered and uncovered, in darkness and in light. Have tried two different batches of seed from different suppliers and still no joy. Any advice gratefully accepted (apart from "give up"). These plants are needed for a PhD project.
