Opinion
"
With a unique purple colour in the winter, it is no wonder that this is one of the most popular junipers on the market. It is easily propagated and adapts to many different weather and soil conditions. The species is native to Canada and the northern United States. It seems to be highly susceptible to Phomopsis blight: this seems to be the only downfall to this beautiful, easy to care for ground cover conifer.
