Your plant, one of my favorites) is Bush Ivy (Fatshedera lizei). It is important to understand how it grows to use it correctly. Unlike other ivies, it does not have little roots that cling. It must be supported (espalied) on a wall, fence or pergola. As it matures in your zone it will send out branches that could be 12' long and it becomes very heavy so needs a strong support. It can be pruned back and controlled any time of the year. I have grown it on a fence using tiers of grape wire supended through screw eyes and the branches afixed to the wire with single wrap velcro. Also, the entrance to my garden in a former home was a strong arch with Bush Ivy secured to it. In the late winter you will note quite a bit of yellowing and dropping leaves. Normal situation not to worry about. Hopefully you can find a growing situation for this plant. It is a beauty.

Hi FW - I had the same problem when I wanted to post a photo and actually had to go through the other GW forums to see how other people did it. I then subscribed to Photobucket, which allows you to upload photos to your account (free) which in turn gives you a code to paste into the GW forum message. You don't actually insert the photo to the message, just the code. Photobucket actually hosts your photo via the code. Once you've used it a couple of times it is quite easy. It is a pity there isn't a similar feature in GW - as you say.
