Flower growers may have such fears that the temperature is too low and the cultivated flowers cannot grow normally. But a new plant grown by botanists has super cold resistance. It is a type of petunia that can be used to prevent freezing. The vitality of this flower is so tenacious that it can even be safe for the winter.
Petunia is one of the gardener's favorite flowers, from spring until autumn, but often the first frost of the fall ends the flowering period of petunia flowers. However, after ten years of experimentation, scientists have cultivated a petunia flower variety that has a more persistent vitality.
The new species is named "sub-zero" and can withstand temperatures as low as minus 10 degrees Celsius. It can extend the flowering period until the summer flowers disappear, and in the cold winter, it still blooms in the face of frost and snow.
This petunia blooms five to six shades of pink, purple, and red flowers. The test site was selected at the foot of Mount Vesuvius in Italy, where the winter temperatures are very low, reaching a minimum of minus 10 degrees Celsius.
