Hardy Cycads

Juniper Level Botanic Garden - An Ex-Situ Conservation Garden

Our Mission is to Collect, Study, Propagate, and Share

As of 2020, JLBG has just over 27,000 taxa of living plants, making the collection one of the most diverse in the world. Fundraising for an operational endowment to preserve the garden is underway, administered by NC State University. If you'd like to help preserve the gardens and plant collections for future generations, you can do so with a tax-deductible contribution at JLBG.org and click on the Donate Link.

At Juniper Level Botanic Garden, part of our mission is to educate and share both plants and information. This photo/informational gallery is devoted to cataloging as many winter hardy cycads as possible and the temperatures that they have endured for us without any winter protection. Planting dates are given when you click on the larger images and can be referenced back to the winter temperature chart.

Low temperatures recorded are days below 20 degrees F with the dates on which they occurred. Temperatures of single digits F, are highlighted in red
