Frost resistance — Erica gracilis
Erica gracilis J. C. Wendl.
Erica gracilis is a thermophilic species with a critical tissue damage threshold ranging from –2 °C to –8 °C. Due to its low winter hardiness, the plant is not suitable for perennial outdoor cultivation in temperate climates.
In the reference 5 varieties crop Slender heath, where this is mentioned in the description.
Erica gracilis is characterized by low frost resistance, attributed to the species' South African origin. The threshold temperatures at which plant tissue death occurs range from –2 °C to –8 °C. Studies on the hardiness of this species are conducted using the controlled freezing method on dormant shoots after prior artificial hardening at temperatures between –1 °C and –3 °C.
The low frost resistance levels dictate the agronomic practices for this crop, which is most often grown as an annual or a potted plant. When temperatures drop below the critical threshold, the aerial structures of the plant sustain irreversible damage; therefore, to preserve Erica gracilis in regions with cold winters, it must be moved to frost-free indoor facilities.
