Plant once. Harvest for a decade.
These nine perennial vegetables skip the annual cycle of buying transplants, prepping beds, and starting over.
Asparagus produces for 20+ years from a single crown. Rhubarb delivers 15+ years of stalks. Walking onions replant themselves when their topsets bend over and root into the ground.
Jerusalem artichoke yields around 10 lbs per plant with almost no maintenance. Sorrel and lovage come back each spring. Good King Henry works as a spinach substitute. Sea kale produces blanched shoots for a decade.
Horseradish is the one to contain — it spreads aggressively. Give it a buried barrier or its own bed.
The two-year wait for most of these is the price of not buying starts again.
