This was interesting but it suffered a lot of winter burn and never really recovered. I live in Zone 6 Northern NJ.

I was looking for something unusual to plant out in matching containers on either sides of the path entrance in my new garden...I looked for months - then I found these very unique little evergreen shrubs and snatched them off the truck at the nursery before they even had them out for sale. They are very small, great for containers, grow VERY slowly, and must be appreciated up close, they really would get lost in big beds or borders... The leaves are tiny, packed along the stems attractively, and are variegated gently - not at all brash as some of the shrubs can be. Great for rock gardens, troughs, bonsai. The branches twist, and curve into a neat silhouette, with no pruning. Just a neat new plant - look for one near you!!! :-)

Miniature Euonymus, slow growing and suitable for trough or containers. Leaves serrated and very small, deep green with a reddish tinge in cold and sun on upright stems. Very compact.
