When designing a garden I always add is what I call "cuttables" , to any planting list I create. Those wonderful evergreen boughs and berries we all seem to decorate with come the holidays.
Nothing gives me more satisfaction than being able to stroll through my gardens clipping and gathering an assortment branches, be they needled conifers or evergreen leaves such as hollies and box woods, all for indoor display.
As gorgeous as the blog post have been these past few weeks, with all the wonderful winter arrangements, please remember that the majority of colorful berries being used are poisonous to small animals as well as children. Once cut and brought indoors these berries become dry and easily fall off their branches.
carolynerohme.comTreehugger.com did a very informative post on poisonous berries a few weeks back, that you can read here. Though not a complete list it will give you a good idea as to what to avoid when building your display.
Alternatives? You might want to consider the following,
Nandinia domestica 'Alba'
Junipers, for their berries as well as foliage
Pyracantha, in wonderful shades of reds as well as oranges and yellows
Or better yet try mixing faux berries with your fresh cut evergreens, as Cindy Hattersley of Rough Luxe Lifestyle did in this charming basket.
