That is really beautiful, please take another picture when the tree (or trees since there are two different colors?) are in full bloom. I wish my yard was large enough for a witch hazel. There are two varieties, the common and vernal, that supposedly grow down here but I have never seen them in any garden center.
Sadly, the bushes are still babies so they have not yet become spectacular border fillers. We have I think 7 of them at present.
The astringent Witch Hazel is extracted from the leaves and bark of the Hamamaelis virginiana. It's great for skin care from acne to sunburn.
Lovely colour. We want to have one or two of those, but haven't gotten round to it yet. The late winter colour is very welcome.
