They did not continue to grow for me.
Perhaps they needed more light than a winter south window.
If I did these again, I would place them under lights in the basement.
Winter sowing is also a good idea as they probably would not sprout until the spring light was here.
It is important for some of us gardeners to try to preserve some of the plants from the Himalayas as many are on the brink of extinction. The recent earth quakes there are more reason for us to try,---- as I expect many plants were lost in the quakes.
Good Luck!
