USDA Hardiness zone: Zn4b -20º to -25ºF

Foliage color:

Foliage season:

Blood thorn rose. Justifiably famous for the sanguine glowing red hue of the thorns on new growth. Back lit by the sun it would make a vampire very very hungry. Large growing species rose that also features 1″ fragrant single white flowers en masse on wood from the previous season. Established plants (1-2 years in the ground) may be coppiced in early spring to emphasize and create new wood clad in thorns. If allowed to mature a year  or two the thorns fade  to gray but then you are rewarded with scintillating flowers in May/June. Full sun and virtually any soil, including heavy clay. But avoid standing water in winter. Average, regular irrigation in summer keeps it looking fresh. Old specimens can make do with little water. If you do coppice this plant for thorns make sure you follow up with a bit of fertilizer (a handful of all organic fertilizer 9.3.4) and regular water to ensure regrowth is robust. Winter deciduous- fall color is orange red and brief. Bright red, shiny hips follow a profuse blooming season. Long lived. To 8′ x 8′ if left unpruned. Regrowth on hard pruned shrubs in a season can be almost as big. Disease resistant, virus free and produced on its own roots. Light deer resistance.
