Freezing suitability — Impatiens walleriana
Impatiens walleriana Hook. f.
Impatiens walleriana is a tropical plant with no tolerance to sub-zero temperatures. Any exposure to frost causes irreversible damage to the crop's succulent tissues.
In the reference 10 varieties crop Busy Lizzie, where this is mentioned in the description.
Impatiens walleriana lacks biological mechanisms to protect cells from the freezing of intracellular moisture. At temperatures below +10 °C, the plant undergoes severe stress, and short-term frosts lead to rapid tissue death, resulting in loss of structural integrity and disintegration.
In agronomic classification, the crop is categorized as non-winter-hardy and tender. Breeding programs aimed at improving frost resistance in this species are not conducted, as all existing cultivars of Impatiens walleriana are incapable of surviving sub-zero temperatures at any stage of vegetation.
