Solanaceae: perennial to 140cm, a rarely cultivated Asian perennial with large pale greenish yellow, bell shaped, nodding flowers followed by a greenish berry in an inflated calyx above large, plain green leaves on loosely branching annual stems, for any humus rich, slightly moist soil in a partially shaded to sunny spot. Native to China, Nepal, India and Bhutan, in China it is in Sichuan, in southeast Tibet and northwest Yunnan to find. It grows on grassy slopes and near mountain streams at altitudes from 3200 to 4200 m.
Very easy to grow here, the grow tall and have very large deep roots, they also have a habit of failing over, so you will need to support them in some way, a lot of flowers failed to be pollinated for some reason, and in the end I started to hand pollinate them in order to get a supply of seed. All seeds from this species will need a cold treatment or a soak in GA3 before they will successfully germinate, germination is about 4 weeks. Seeds can either be mixed with a little damp sand in a sealed bag and placed in the fridge for 4-6 weeks or you could try soaking the seeds in a solution of GA3, which can be found on eBay and other online retailers, this works really well with many plants of the Solanaceae family.
