So here's what I did. I took cuttings of several large branches of a red twig dogwood, an eastern red cedar (Juniper), and some berries from a nandina. Then I added the evergreen juniper branches to the soil. (I had to wet the soil first because the soil in the pot was frozen!) I arranged the juniper branches to shield the cordyline from view and to offer them a little more winter protection. Then I placed the red twig dogwood branches where they would be highlighted against the evergreen juniper background. Last I added the nandina berries to the pot. I didn't want to remove a bunch of berries from our nandina since we have only the one but a couple bunches of berries from the back of the shrub won't be missed.
Here's how the arrangement looks now:
I could probably squeeze in a few more red twig dogwood branches and maybe some pyracantha berries. Maybe I'll change out the red nandina berries for the pyracantha after the New Year. I wouldn't bet $10,000 on it but there's a possibility that could even have some rooted shrubs in my potted arrangement by spring!
Now I just need to add a big old Christmas bow!
