Corlis Bolton Haynes Sunchoke

Corlis Bolton Haynes Sunchoke

Species: Helianthus tuberosus, Sunchokes are also known as Jerusalem Artichokes or J Chokes

History: Corlis Bolton Haynes discovered a wild sunchoke growing on the farm her parents purchased in 1925 and then spent over sixty years selectively planting the biggest and smoothest tubers in order to improve on the plant. Corlis sadly passed away in 2003 but her family maintains the tradition of only replanting the biggest and best tubers. 

Why We Grow It: This variety produces large, white, knobby tubers that like a potato can be prepared and eaten in a variety of ways! This variety is quite productive and the tall plants can be used as a temporary windbreak and/or privacy screen.

Shipping vs. Pick Up

CLICK HERE to see how shipping compares to pick up.

Shipping: Every year we ship thousands of trees across Canada (except BC due to CFIA regulations). We carefully bag roots in damp sawdust, then box them and send them out via courrier. CLICK HERE to see our shipping policy.

Pick-up: We also have thousands of trees picked up from our nursery each year. The pick-up options is free, though you must wait until you have been emailed a confirmation that your order is ready to pick up, which will have further information such as hours, locations, etc. We really appreciate if you can make an appointment to pick up, then we can be as organized as possible during our busy season.

Size at Purchase

Our bareroot perennial vegetables are sold as root crowns or tubers and will often have little to no vegetative growth on them. Depending on the plant, you may receive one or two root chunks, crowns, or tubers per order. The size varies significantly between species.

Like with our other plants, we recommend planting our perennial vegetables dormant so the transplanting process is less stressful on them. As a result, they may not look like much when you receive them but they tend to start growing fairly quickly.
