Hi Olaf! A plant in height of 1,50 m. The plant from a seed, to it about 2th years grows. Before landing in a ground, it grew in a pot, approximately 1,5 years. A beautiful version. Olaf, you correctly thought. At us sharp and cold winters. There is a temperature falls to-40 degrees and more low. A greenhouse with heating. During winter time temperature in it of +12+15 degrees. Plants feel very well. Ken, most likely seeds won't be, I this time didn't make pollination. Best regards all!
