Frost Damage on Pseudopanax laetus 'Kiwi Gem'

The last six weeks of spring-like conditions caused several plants to bud out early, including my recently acquired Pseudopanax laetus 'Kiwi Gem.' This is a fairly recent Monrovia introduction which I have only had since last summer. About two weeks ago temperatures dipped down to 29° to 30°F (-2° to -1° C) overnight. Light frost coated everything but left most plants unfazed - except for the new growth on this shrubby aralia relative.

This plant is supposed to be hardy to Zone 7, but we'll see.
