Variety traits

Frost resistance of roses

Rosa L.

A key biological trait of roses that determines the survival of cultivars at sub-zero temperatures. It is assessed using the USDA hardiness zone scale and scoring systems for shoot freeze damage.

In the reference 263 varieties crop Rose, where this is mentioned in the description.

To assess the frost resistance of roses, USDA zones based on minimum temperatures and scoring scales that record the degree of damage to annual and biennial shoots are used. Highly resistant varieties, such as Canadian roses, can withstand temperatures down to –40 °C, whereas Hybrid Tea groups often require covering at –25 °C.

It is important to distinguish between frost resistance and winter hardiness: the latter is a comprehensive characteristic that includes reaction to winter thaws, damping off, and desiccation. Low winter hardiness reduces the lifespan of a bush to a few seasons, while proper cultivar selection and consideration of the site's microclimate ensure the longevity of plantings for up to 30 years.
