Clematis fasciculiflora - silver leaf form
This selection of this evergreen Clematis can likely be traced back to Roy Lancaster's introduction of this choice species from his collection L657 from Emeishan in Sichuan which had the distinct central silver splash on the leaflets which makes this extra luscious. Small scented creamy flowers start appearing in late winter here in the Northwest and on mild winters it is not a surprise to be surprised by flowers happening in February although March is pretty much guaranteed. A classic wall plant where it appreciates the buffer and protection afforded by the wall as well as access to plenty of sun. If you don't have a wall, try a tree as this can reach 20 feet or more but is easily kept in bounds by pruning after flowering if you are hardwired for control. Zone 7b or down to Z7 with appropriate siting.
