Gardeners' Notes:

I wouldn't be without this one. It does ramble but I just pull it where I don't want it. With extra good growing conditions mine appears to revert to mostly green-which is still beautiful. With poor growing conditions it will have much more yellow variegation. Scorches in sun here. See my pics.

In the Pacific Northwest, for the most part, ivy is considered a noxious invader. That taken into account, I do actually have some in my garden and I raise it responsibly. This is one of the Hedera plants I simply couldn't live without. Like the others I have, this one is easy to control and contain. I used it to cover an archway in my garden and it brightens that area and grows happily. The large leaves look very exotic as well and it is always a joy to look at.

Also synonymous with 'Paddy's Pride.' Dark green cordate to entire 6" leaves, with a subtle lighter-green central area with gold veins, and sparse edge-serrations. More tolerant to winter sun and cold than more variegated H. colchica. May loose its leaves in extreme cold, but stems remain alive. A bold alternative to the common H. helix.

This ivy has huge leaves with striking yellow centres. It is not as tender as varieties of Hedera helix, but is well worth the garden space if a sheltered shady wall is available. One of my favourite ivies
