Tulip frost resistance

Tulipa L.

Tulip frost resistance is a complex agrobiological trait of a cultivar's adaptability, characterized by the ability of bulbs to overwinter in the soil and withstand recurring spring frosts.

In the reference 64 varieties crop Tulip, where this is mentioned in the description.

The assessment of frost resistance is based on long-term field monitoring of bulb survival and the ability of vegetative organs to restore turgor after exposure to low temperatures. Under natural conditions, tulips can withstand short-term spring temperature drops down to -12...-15 °C, during which the aerial part temporarily loses its vertical position but recovers upon warming.

Resistance varies significantly depending on the cultivar: Darwin hybrids possess high winter hardiness, whereas double and parrot varieties are more sensitive to adverse conditions. Limiting factors include rapid freezing and thawing cycles, as well as excessive soil moisture during the winter-spring period, which, in combination with planting depth and drainage, determines the overall plant survival in a given region.
