Digiplexis ‘Falcon Fire’ is considered to be marginally frost hardy. It is typically hardy in USDA hardiness zones 8-10, where it can withstand temperatures down to about 20°F (-6°C). In colder regions, it may not survive freezing temperatures and is best treated as an annual or grown in containers that can be brought indoors during winter.
If you live in a colder climate and still want to grow Digiplexis ‘Falcon Fire,’ you can try providing some winter protection. Before the first frost, mulch around the base of the plant with a layer of straw or leaves to insulate the roots and protect them from freezing temperatures. You can also cover the plant with a frost cloth or move container-grown plants to a protected area, such as a garage or basement, where temperatures remain above freezing.
However, it’s important to note that even with winter protection, the chances of survival in very cold regions are limited. If you’re uncertain about the frost hardiness in your specific location, it’s best to consult with local garden experts or a nursery familiar with your climate for tailored advice on growing Digiplexis ‘Falcon Fire.’
