I planted mine last early Summer. I harvested the leaves & stems to make tincture. The tincture was bitter but it worked. I covered my plants in 4-5” of mulch through the Winter months & it came back this Spring. Its tall with little buds on top. The lower leaves don't have as much of the white sap in them like they did last year when I cut them small before the stalks got big. This year I will try to collect the sap & dry it. I blended up the leaves & stems in a good grade of vodka in the blender and let it sit in a dark bottle, in a cool dry place for several weeks before using.
