Rhubarb
Rheum rhabarbarum
Rhubarb is a garden anchor common around old farm houses. It is long-lived and typically grown by dividing the plant crowns. Starting from seed is not difficult but you will need to plant at least twenty seeds to cull out ones that do not exhibit the desired traits for the variety. For the average family, three plants will be enough.
Each packet contains 1 gram or approximately 60 seeds.
