Pass Christian, MS, USA Border of Zone 8B-9A Soil pH 5.5-6.5 Humid air, mostly. I was quite frustrated with ordering seeds from Asia. Ordered GAC seeds many times, and had pitiful germination, partly because of 6-8 week quarantine, and perhaps many of the seeds sold, I think, are old. Managed to get 3 to become vines. Had one in a pot to take in, and two in the ground under oaks with about 2 inches of leaves over the roots. Winter came. One night dipped to 13F, and the freeze lasted about 14 hours. Thought for sure that they were obliterated, but by June they re-sprouted from slightly underground. They grew to about 25 ft. Last Winter we had 5 days below freezing with 2 inches of snow, and nights at 17F, and 19F. Thought for certain that they died, but by late summer they were 40ft... read more

Tried to grow this plant from seed several years ago without success. Recently ordered seeds from unclechan'sgarden on eBay and they were already sprouting when they arrived. I now have two dozen healthy little plants and more coming. I am not related to unclechan and recommen his seeds because they grew when others didn't.katie

So far not so good... I planted 3 seeds in early August growing inside under lights... Never sprouted. I have just planted 3 more in some wondersoil reground and will watch closely.

Until I see one sprout I am leaving this as a neutral entry.

Updated: Look at the picture to see the results growing under lights...
