Why is it that when I think I have an original idea... it turns out it was actually done during the Victorian era? Alas, there is nothing new under the sun. Nonetheless... new to me, this year we are adding fresh flowers to our Christmas tree decorations.
Now there are many ways to do this, you can buy those tiny water vials on Amazon for a few dollars and fill with Peruvian Lilies or orchids. They are long lasting, beautiful, and you will probably only need to change them out twice during the entire season.
Or you can buy small live Poinsettias and using floral wire attach them to your tree branches. You must remember to water, occasionally, but since it is a live plant you don't have to worry about it wilting. I am using the about 6 mini plants inside my tree. I have always wanted to put flowers in my tree but, I find silk flowers sad.
