The lazy productive garden you've been missing
The standard vegetable garden is exhausting. Every spring you start from scratch. Sow, prick out, transplant, weed, water, harvest, clear, repeat next year. The whole thing is built on annual labour.
Perennial vegetables flip the script. Plant once, harvest for years. Some for decades. Once established, most need almost no care. They build deeper roots, they're more drought resistant, they're more nutrient dense, and they feed you with a fraction of the work.
Here are 38 perennial food crops worth a spot in your garden. Some you've heard of. A lot you haven't.
The classics (start here)
- Asparagus. Plant crowns once, harvest for 20 years. Worth its weight.
- Rhubarb. One crown produces stalks for decades. Pies, crumbles, chutneys.
- Globe artichoke. Architectural plant, dramatic flowers, edible buds.
- Jerusalem artichoke (sunchoke). Plant once, harvest forever. Tubers all winter.
- Sorrel. Lemony perennial leaf. Salads, soups, sauces.
- Horseradish. Plant in a contained spot. Roots become condiment heaven.
- Garlic chives. Garlic flavour, perennial habit, gorgeous flowers.
- Chives. Plant once, divide every few years, never buy again.
Perennial brassicas
- Perennial kale ('Daubenton', 'Walking Stick'). Cut leaves for years, never re-sow.
- Sea kale (Crambe maritima). Coastal native, edible shoots, dramatic foliage.
- Tree collards. Tall perennial brassica, productive for years.
- Watercress. Perennial in moist conditions.
- Rocket (perennial varieties). Wild rocket especially.
Perennial onions and alliums
- Walking onions (Egyptian onions). Form bulbils on stalks that 'walk' across the bed.
- Welsh onions. Clumping perennial green onions.
- Multiplier onions. Plant one, harvest many.
- Society garlic. Mild garlic-flavoured leaves and flowers.
- Three cornered leek. Wild garlic, edible leaves and flowers.
Perennial leafy greens
- Tree spinach (chaya). Tropical tree with edible leaves.
- New Zealand spinach. Self-seeds aggressively, perennial-ish.
- Dandelion (eat the leaves and roots).
- Nettle (peak nutrition, just wear gloves).
- Good King Henry. Old English perennial spinach substitute.
- Lovage. Celery flavour, perennial habit, dramatic plant.
Perennial root crops
- Skirret. Sweet, white, parsnip-like roots. Forgotten perennial.
- Hamburg parsley (parsley root). Eat the leaves and the carrot-like roots.
- Oca (NZ yam). Perennial-ish tubers, sweet and lemony.
- Yacon. Sweet juicy crisp tuber from South America.
- Mashua. Spicy edible tuber, beautiful flowers.
Perennial herbs (the easy wins)
- Rosemary. Perennial shrub, decade-plus productivity.
- Thyme. Same. Often spreads into useful ground cover.
- Sage. Long-lived bush.
- Oregano. Spreads, lives for years.
- Marjoram. Same family, same habits.
- Mint (in a pot). Plant once, contain it, forget it.
Perennial fruit (technically vegetables in our kitchen)
- Strawberries. Perennial, runners produce new plants annually.
- Cardoon. Globe artichoke cousin, edible stems.
- Asparagus pea. Quirky perennial legume with winged pods.
How to start with perennials
Don't try to plant 38 in year one. Pick three to five that genuinely interest you, plant them in autumn (most perennials establish best in cool weather), and let them settle for a year before expecting much.
Year one is for roots. Year two is for first proper harvest. Year three onwards is when the savings (and the dinners) really start.
Designing with perennials
- Put them in a dedicated bed (or 'perennial corner') so they're not disturbed by annual planting.
- Choose sunny, well-drained spots for most.
- Mulch heavily. Perennials live in their soil for years, so soil quality compounds.
- Label everything. By year three you'll forget what's what.
- Mix with perennial flowers and herbs for a forest-garden feel.
The honest bit
Annual vegetable gardening will always be the front of the patch. But a serious perennial corner changes the garden's relationship with time. Less re-planting, less re-sowing, more harvest from less effort.
