That particular one is one of the Lace Cap Hydrangeas. If you want to grow them they are widely available in many varieties. But be warned. In many parts of the UK the flowers will not be blue like that but a muddy pink. You need acid soil to get that colour.

I know it's a weed but the red stems and beautifully colored berries do make it attractive. Our Cardinals eat the berries and spread the seed all over from number of seedlings I pull out. I hear the "chip-chip" of the Cardinal and see the whole bush richochet when they pluck off a berry. Berry color is not appreciated on cars via bird distribution network...LOL. Didn't have any idea what it was 3 years ago when it first appeared at top of driveway. Since I'd been over zealous in hacking out Chinese Wisteria thinking something else would grow there (it won't) I thought it would at least fill the huge hole I left in a very visible spot. Two clumps spread and spread and spread. Didn't find out what it was until year #2 when people here on GW said they were looking for the variegated variety and making sure they didn't have them close to straight green giants or risk losing variegation. Figured it was a worthwhile "specimen to naturalize" if people were buying it. Since I've let them be for 3-4 years I couldn't get them out if I wanted to because they've grown right into the ungodly matrix of underground Chinese Wisteria runners as big around as my arm. I just pull them down after killing frost in Fall and figure the garlic mustard and Chinese Wisteria cause many more problems and are impossible to eradicate since those two are all over the area no matter how much I pull & chop on my father's property. coolplantsguy, the photo of those berries is beautiful! The deer eat the plants but they haven't shown any "ill effects" at all. ): Must not like fruit...just poke salad, hold the dressing.

Found the Name that plant forum :) and posted my query there. http://forums2.gardenweb.com/forums/namegal/?32146 Please pardon me being a noob and posting here :)

Hemlock, as in Socrate's demise. The stalks will be mostly hollow, and at the base of the stalks they will be kind of chambered and have some brown "sap" in the chambers, which is the concentrated poison as I understand it. I don't think any of the plant would really be safe to eat, though.
