However, even nearby populations can differ in cold hardiness.

'Lula' became recognized for its excellent eating qualities, steady production, and cold hardiness.

This plant is not productive elsewhere in the U.S. due to disease susceptibility and lack of cold hardiness.

Aside from cold hardiness, Vitis acerifolia provides many potential benefits for the breeding of hybrid grapes.

It is grown due to its phylloxera resistance and its cold hardiness.

This cold hardiness is separated into two categories, freeze avoidance and freeze tolerance.

This cold hardiness enables it to survive brief temperatures below freezing, provided that adequate shelter and feeders are available.

But cold hardiness is not always the criterion.

It is widely known for its extreme cold hardiness and its slow growth compared to other palmetto species.

"But I don't see them growing in popularity until we conquer some major problems, like cold hardiness and susceptibility to black spot," he said.
