Cultivation
Freezing tolerance of Lobelia erinus
Lobelia erinus L.
Lobelia erinus is a thermophilic plant with low resistance to sub-zero temperatures, which cause the death of its vegetative parts.
In the reference 5 varieties crop Edging lobelia, where this is mentioned in the description.
Lobelia erinus falls into the category of frost-sensitive plants, as it lacks genetically determined winter hardiness. Due to its origin in regions with a warm climate, it is cultivated exclusively as an annual crop in temperate latitudes.
The plant is unable to withstand tissue freezing. Upon the onset of sustained sub-zero temperatures, the vegetative mass of the lobelia perishes. Despite the ability to tolerate short-term temperature fluctuations down to -7°C, the plant requires transfer to protected ground to maintain viability.
