Hansa rose
Rosa rugosa 'Hansa'
Hansa rose (Rosa rugosa 'Hansa') is a shrub suited to the Colorado Front Range. It matures to about 4–5 ft tall and 4–6 ft wide, needs low to medium water, and prefers full sun. An intensely clove-scented rugosa: magenta-purple double flowers, big tomato-red hips, and bulletproof toughness (salt, wind, poor soil, cold to zone 3). It suckers into a thicket, so give it room.
