Shrub rose: Rosa Hansa
![]() 'Hansa' was bred in Holland and introduced in 1905; it bears red-violet blooms. Like other rugosa roses, it descended from the rugged and hardy native Japanese species. Rugosas are known for deeply veined, rugose (heavily etched and crinkled) leaves, are free and continual flowering, and have large, attractive, and edible orange-to-red hips. Typically, rugosa hybrids produce single-to-semidouble flowers, ranging in hues from whites to yellows and pinks to reds. Profile
did you know?A rose’s fragrance comes from its leaves and sepals as well as its petals. The production of 2 pounds of attar of roses, the essential oil used in perfumes, requires the fresh petals of about 1 million rosebuds. general maintenance:When leaf buds open in spring, remove winter-damaged branches, and crossing and weak canes. After early-summer flowering, cut back remaining canes by a third to half. Deadhead unless decorative hips are desired; north of Zone 7, allow hips to develop in late summer and fall to prepare bush for dormancy. pests/diseases:Fungal diseases (black spot, powdery mildew) may stunt and discolor leaves or defoliate entire shrubs, especially in humid regions. Common pests include aphids, spider mites, and Japanese beetles. controls:To discourage fungal diseases, avoid wetting foliage, and remove and dispose of fallen leaves. Spray a mixture of 4 teaspoons baking soda and 1 tablespoon horticultural oil per gallon of water; repeat weekly. For aphids and spider mites, use horticultural oil, following package directions. Handpick Japanese beetles, and destroy. how to sow/plant:Choose a sunny site with fertile, well-drained soil, and amend with well-rotted manure or compost. Plant container-grown roses in spring or fall (at least a month before frost), at the same level they were in the pot. Plant bare-root roses in early spring; before planting, soak entire plant in water for 12?24 hours to replace lost moisture. Dig a 2-by-2-foot hole. Return some soil to hole, forming a 1-foot mound. Place plant on the mound, fanning out roots. In Zones 6 and warmer, set bud union just above soil level. In Zones 5 and colder, set bud union 2?4 inches below soil level. Cover roots with soil, and water thoroughly, but do not fertilize at this time. water and fertilize:Monitor soil moisture all season; use soaker hose to give roses an inch of water weekly during dry weather. Once newly planted bare-root roses break dormancy, feed with an all-purpose fertilizer at half rate, following package directions. After the first season, feed with balanced organic fertilizer in early spring and again in early summer at first bloom, and spray bushes with kelp extract in early fall. features:
