Grow Your Own - Rhubarb (Rheum rhaponticum)
An easy plant to grow, rhubarb will remain productive for many years.
This ancient plant has medicinal value and was originally used solely for this purpose. The leaves are poisonous since they contain oxalic acid.
Cold temperatures breaks the rhubarb's dormancy. Once the snow is gone it is a good time to start forcing rhubarb with a container that will exclude light, but of sufficient height to allow the stalks to grow.
The container can also be filled with straw to act as insulating material. Forced rhubarb is delicious - the stems are more tender, sweeter and do not need to be peeled.
