There are very few evergreen vines for gardeners in the Pacific Northwest, but this gorgeous gem from Asia is  becoming more readily available and it’s simply one of the coolest flowers you’ll ever get to witness opening. From plump, peony-like buds, they begin to slowly crack open, a froth of fertile flowers begin to form and over the course of a few days, a flat umbel “lacecap” begins to form.
