Does it like some shade? Our “full sun” is brutal (we’re transitioning from semi-arid steppe to full-on arid). Also, does it require himidity?
Shan Yao (Chinese Hardy Yam Vine) requires full to partial sun, loamy loose soils, and moderate moisture. It is much like a sweet potato, though superior in nutrition and some believe flavor.
Will this vine do well in a large 10-20 gal container? If so, how deep? does the vine need support such as a trellis? How tall will the vine grow in the season?
Yes, understanding that the "fruit" for this plant is the root tubers themselves. It is a fast growing vine that needs support and can grow up to 16 feet in a year. Roots mature in 3-5 years for harvest and replanting.
Hello - I received this in my spring shipment in early March. There is no visible plant. It is a 1 gallon pot of just a tuber? Just want to be sure before I build a trellis for it. Thanks!
That is normal. The vine dies back annually and regrows from the tuber, which is the part of the plant you want.
Plant arrived during a time that was still below freezing. The plant was well wrapped and looked in great health. The vine was about 2 feet long when it arrives, however about 4 inch of rip froze. I trimmed it down to the the next leaf segment. It has since grown a ton and am so happy with the purchase. This year is my first year ordering plants from Braintree and I am so happy with the quality of all the plants purchased.
