small yellow flowers with purple veins in the early spring, produced on 1 year old stems
dark glossy green leaves during the growing season, turning to red and oranges in the fall
armed with spines
a compact globular mound reaching 2 by 2 feet
A combination of the dense foliage and the spiny stems make this plant a real garbage collector. Grabbing onto any piece of paper that blows through the yard. To avoid lots of punctures and scrapes, a good pair of gloves and a long sleeve shirt are required when cleaning this plant in the spring. Some pruning may be needed to maintain shape. If you like the flowers pruned after the blooming period.
Van Klavern of Boskoop, Holland, 1960
