Best time is to plant now, autumn, and keep it watered till winter sets in properly. You might find it doesn't cling by itself initially, but it will as it grows. The only negative thing I'd say is, its fine so long as you don't mind heights up a ladder. You will need to ensure it does not get up to the guttering and the fascia board beneath it - it has a tendency to invade underneath or over the top of the gutter, and it could end up in your roof space. But so long as you can keep it pruned when necessary, should do a good job, although its not, of course, evergreen.

Thanks for your reply Bamboo, much appreciated.

I find Chinese Creeper slow at getting started. It is also not evergreen. Can you mix it with a nice evergreen Ivy? As you will end up with half a years worth of wall inviting graffiti with something else covering up the wall itself.

Hi Kildermorie, I looked at Ivy but I understand this can be damaging in the way it attaches it-self into brick work where-as the Henryana uses suckers. Guess I need to reconsider my approach.

Thanks all.

You're right about ivy, it does damage mortar and brickwork. That said, though, Parthenocissus can cause damage if the brickwork is very old, flaky and needs repointing.
