|Is the Rosa Rugosa able to survive a winter in zones 2-3?|
|Rosa rugosa is a wide-ranging species which occurs naturally in Siberia, Northern China, and Japan, where it can be found growing near the seashore and on sand dunes. As its habitat might suggest, Rosa rugosa is a tough, hardy rose that can withstand extreme cold, strong winds and poor soils. It is one of the very few rose species which is naturally reblooming.
The species is peculiar and distinct in its appearance. The foliage is dense, with blunt, heavily wrinkled (rugose) leaflets. The typical Rugosa is bushy and upright in habit, with many thick, viciously thorny canes. The hips are generally very large and conspicuous, though hybrids and cultivars vary considerably in their fruit production.
It should thrive in a sunny site in your Alaskan climate.
