Clematis on the Arbor

I planted Clematis on my arbor 2 years ago and thought it was a gonner when I saw it peter out the first year and was weak last year. This year all of a sudden it is revived and there are buds. I quickly replaced the other side of the arbor with what I think is the same variety thus having hopefully matching plants growing up each side.

Niobe Clematis:
Prune Hard
Blooms June-July
Height 4-6'
Zone 4-8
Flower 6-8" velvety dark red flowers with cream stamens

Clematis needs moist, well drained soil with an exposure of one half a day to a full day of sun. The plant should be mulched and kept moist, especially during the first growing season. Fertilize every four weeks during the growing season with a well balanced liquid fertilizer.

Clematis's feet like to be shaded.
