Winter hardiness of Penstemon

Penstemon Schmidel.

A key biological trait of Penstemon that determines its introduction potential and survival during the winter period. Successful overwintering depends on the genetic frost resistance of the cultivar and the critically important tolerance to waterlogging during the cold season.

In the reference 12 varieties crop Beard Tongue, where this is mentioned in the description.

The assessment of winter hardiness in Penstemon is based on the plants' ability to withstand low temperatures, which is classified according to USDA hardiness zones (from zone 3 to 9). Varieties show significant differences in this trait as they originate from different climatic conditions, with some species capable of withstanding temperatures as low as -34°C.

Resistance to waterlogging ('wet feet') plays a special role in the wintering of Penstemon; therefore, creating proper drainage is a key agrotechnical requirement for increasing survival rates. In regions with cold winters, mulching the root zone with organic materials is additionally used to protect the plants.
