It would need watering in the first year. After that it should be able to fend for itself.

How about Garyia Eliptica which grows long catkins and can be quite eye-catching?

euonymus fortunei 'Emerald n Gold' isn't strictly a climber but when planted against a wall/fence will grow up it to about 4-5ft.I love it although I normaly hate variegated plants .Its as tough as old boots and I have moved one plant 4 times and it still won't die.
For year round interest I would plant a combination of euonymus and jasmine.
