There are hundreds of H. helix cultivars. Most have green leaves, but the variegated and novelty forms tend to be less hardy. Wilson's English Ivy is cold hardy in Zones 5a/b, but may still be damaged somewhat in harsh winters or in exposed locations. I bought this cultivar in a "10-pack" with the express purpose of introducing it to climb on large mature oak trees. It has, after eight years, done that real well, and has covered the trunks of some large trees up to a height of 20-25 feet. It has also withstood winter temperatures down to -20F with bone-chilling winds with no major damage. It can tend to spread out at the base of trees and spread into grass. However, a shovel can be used to keep lateral growth in check around the tree base. Foliage is attractive year round, but is a fresh dark green in summer months.
