Jerusalem Artichoke

Jerusalem Artichoke

Helianthus tuberosus

Jerusalem artichoke is a perennial root vegetable native to Eastern North America. Domesticated by First Nations in Eastern Canada, this highly nutritious and productive plant is a truly Canadian food.

Produces sweet, crunchy tubers with a nutty flavour reminiscent of sunflower seeds when eaten raw. Cooked tubers become even sweeter with a creamy consistency similar to potatoes, making them versatile for boiling, baking, frying, pickling, or eating raw. Their high inulin content makes them an excellent prebiotic, supporting gut health and balancing blood sugar levels.

Companion plants like corn, beans, and squash complement Jerusalem artichokes by creating a supportive garden ecosystem.

Where Can You Grow Jerusalem Artichoke

This hardy perennial thrives in Zones 3-9 and prefers well-drained soil in full sun. Jerusalem artichokes are easy to grow in garden beds or naturalised areas. They are drought-tolerant once established and require little maintenance.

History and Historical Uses

Jerusalem artichoke has been a staple food for centuries, originally domesticated by First Nations in Eastern Canada. Its resilience and nutritional value made it an essential part of traditional diets. Today, it is celebrated for its role in sustainable agriculture and its unique contribution to North American food heritage.

Canadian Zone Information

  • Zones 8-9: Plant tubers in early spring or late winter for strong growth.
  • Zones 5-7: Plant in spring after the ground has thawed and harvest through winter.
  • Zones 3-4: Mulch heavily to protect tubers during winter and plant in spring.

How to Grow and Harvest Jerusalem Artichoke

  1. Planting: Plant tubers in thawed soil as soon as you receive them, 10-15cm (4-6in) deep and 45-60cm (18-24in) apart.
  2. Watering: Water well during establishment; once mature, the plant is drought-tolerant.
  3. Harvesting: Do not dig in the fall. Wait until stems have died back and harvest throughout winter for fresh produce.
  4. Replanting: Save your largest tubers and replant directly into new beds as you harvest to encourage larger tuber growth and prevent the plant from taking over your garden.

Seed Saving Tips for Future Supply

Jerusalem artichoke is propagated through its tubers rather than seeds. Follow these steps for replanting:

  1. Choose the Best Tubers: Select the largest and healthiest tubers during your winter harvest.
  2. Replant Immediately: Move tubers directly to a new garden bed as you dig, planting 10-15cm (4-6in) deep.
  3. Avoid Overgrowth: Rotate planting locations yearly to encourage larger tubers and prevent the plant from spreading uncontrollably.

Care Instructions

Seed Potatoes

If you receive your order in the fall or winter you will need to store your potatoes until spring. 

Storage: Store potatoes in a cool (not freezing), dry, dark, and rodent-free place. Store in a breathable material like a paper bag or cardboard box to prevent condensation, which can lead to mould. Find an area with good air circulation that won’t dry your potatoes out completely. Check potatoes every 2-3 weeks and remove any that show signs of rot. Potatoes may become soft and wrinkly or sprout in storage. This is normal, simply handle these tubers with care.

Planting: Soil is ready for spring planting when the ground outside is about 7°C. Potatoes should be planted whole. Plant potatoes in holes 25-38cm (15-20in) apart and cover with 6-8cm (2-3in) of soil. A late frost after planting is okay as long as your potatoes are covered. 

Jerusalem Artichokes

If you live in Coastal British Columbia, you can plant your tubers immediately upon receipt. Jerusalem artichokes are stored best in the ground as they can be frozen solid and still survive. *Small tubers included in your shipment have been added as bonus and can still be planted*

Storage: If you must store your tubers out of the garden, open the bag and place in the back of your fridge. Check the tubers inside every 2 weeks. If any show signs of mould, rinse them off, dry gentle, and return them to the bag ensuring they are fully covered in sawdust. Keep the sawdust lightly moistened only if you noticed it has become dry and the tubers start to wrinkle.

Planting: Plant tubers whole, 46 cm (18in) apart and 6cm (2in) deep. If your ground is already frozen, use a shovel to loosen the soil and dig a small hole. Thaw the soil you remove. Plant tubers as instructed and cover with the thawed soil to ensure tubers are covered completely with no air pockets.  

Comfrey and Horseradish (Taproot Rootstock)

Storage: 
If you must store your roots out of the garden, open the bag for ventilation and store in the back of your fridge. Check roots every 2 weeks. If any show signs of mould, rinse them off, gently dry, and return them to the bag ensuring they are fully covered in sawdust. Lightly moisten the sawdust only if you notice it has become dry and the roots are shrivelling. 

Planting: Your roots should be planted flat in unfrozen ground 60cm (2ft) apart and covered with 4cm (1in) of soil. Water in well. Roots can be planted in the winter if you live in Coastal British Columbia, cover with additional mulch to prevent the roots from freezing. Comfrey and horseradish will establish deep tap roots that will survive freezing in future years.

Dahlias

Dahlias are delicate and must be protected from freezing in all locations.

Storage: Upon receipt, store tubers in the bag (opened) in the back of your fridge or in a cool dark cupboard through the winter. Find a balance of good air circulation to prevent moulding without drying out the tubers. Dried dahlias will not sprout in the spring. Check on your dahlias every 2 weeks.

Planting: Plant your dahlias once danger of frosting has passed and the soil temperature has reached 15 degrees C. Plant your tubers flat with the eyes facing up. Cover with 5cm (2in) of soil and water in well. For earlier blooms, you can plant your tubers in a pot as instructed and store indoors or in a greenhouse until safe to plant outside. 

Hardwood Cuttings 

As you unpack your dormant cuttings you will notice one end is cut straight while the other is angled. This is to indicate the “up” and “down” ends of your cutting.

Storage: Ideally cutting should be planted immediately, but if you cannot, store them sealed in their bag in the back of the fridge.

Planting: Cuttings can be planted immediately upon receipt in coastal British Columbia. Push the angled end of your cutting ⅔ vertically into loosely worked soil amended with a small amount of compost. Water in well. – Cuttings can be started in their permanent location, but you may wish to first root your cuttings in a garden bed where they are easier to manage. Plant cuttings as instructed above spaced 15-20cm (6-8in) apart. Leave in your bed for the first year until rooted before transplanting them to their final location. If planting directly into your desired permanent location, ensure your cuttings receive adequate water in their first year and manage any nearby established plants so your cuttings do not become out-competed. 

Nettles and Mints (Shallow Rootstock)

Storage: If you cannot plant immediately, open the bag for ventilation and store in the back of your fridge. Check roots every week and plant before they show any signs of mould.

Planting: In Coastal British Columbia, your rootstock can be planted upon receipt in a large planter pot, garden bed, or naturalized area. Nettles and mints appreciate rich, moist soil. Roots should be planted flat in loosely worked soil amended with compost. Plant with any sprouts facing upwards and any emerging roots down. Cover with 3-4cm (1in) of soil and water in well. Add a light mulch of leaves or other similar material to prevent roots from freezing solid. If planting in a naturalized area, clear other competing plants away from your roots so they receive adequate light to establish.
