Rhubarb is now in stock at Countryside Gardens. A perennial vegetable used in pies, tarts and sauces. Rhubarb should be planted in an area in the garden where it will not be disturbed since it may be productive for five years or more. A half-dozen plants will provide enough rhubarb for a family of four. Did you know Rhubarb is also a great nectar and host plant for butterflies.
