Echinacea purpurea.

I needed some plants for our garden that roe deer do not eat. I checked on internet and made a list with several names of such plants.
I bought some today, for instance this one the echinacea purpurea or purple coneflower. It is maybe good to have this echinacea purpurea in the garden, it says it can stimulate the immune system, for instance against cold.
