Kinds of Roses With the Biggest Thorns

While many modern rose (Rosa spp.) Varieties concentrate on showy blossoms and comparatively thornless stems, large-thorned roses are still in cultivation. These crops include some classic cultivars, and gardeners plant them to create hedges, fences and other barriers. You can plant thorny rose cultivars for ornamental purposes or to maintain undesirable animals from your landscape. Many thorny rose varieties are incredibly durable and can be grown under a wide range of conditions, which makes them suitable for tough microclimates.

Climbing Roses

Climbing roses are notable for their long canes and tendency to climb arbors, gazebos along with other structures. These plants often create clusters of smaller flowers, however a few large, showy varieties are readily available. Climbing roses can be exceedingly thorny, which makes them difficult to prune but successful as a hurdle. Hardy at U.S. Department of Agriculture zones 4 through 11, vigorous, thorny climbing varieties like “Mermaid” (Rosa hybrid) and also “Kiftsgate” (Rosa filipes) create durable additions to most gardens.

Ornamental Thorny Roses

Some rose varieties are precious particularly for their thorns. These include the unusual southern Chinese winged thorn rose (Rosa sericea subsp. Omeiensis f. pteracantha). This plant has bright red, sawtoothed thorns that include winter colour to gardens long after the blossoms have dropped. Winged thorn roses grow well in USDA hardiness zones 6 through 9 and prefer sandy to clay loams with full sun.

Rugosa Roses

Originally from Asia, Rugosa roses (Rosa rugosa) are one of the hardiest options available. These plants grow and bloom vigorously throughout spring and summer, sporting medium-sized aromatic flowers, wrinkled leaves and dense thorns on all the stems. Rugosa roses are especially desirable in gardens where erosion is a severe concern. These varieties may also withstand salt spray and also somewhat saline soil, which makes them a good choice for coastal gardens in USDA zones 3 through 9.

Shrub Roses

The tree rose group involves a high number of cultivars that aren’t closely related but have a comparable bushy growth habit. Several of those roses are incredibly thorny, including “Othello” (Rosa hybrid), some red double-blooming cultivar that creates dark leaves and thick, bushy growth. “Henri Martin” (Rosa centifolia) is just another shrubby cultivar notable for its thorns, and is used for informal gardens in sunlight. Gardeners who prefer smaller roses might look at planting “Dresden Doll” (Rosa centifolia), some miniature moss shrub rose with long, fine prickles over all of its stems and buds. These roses are frequently more delicate than scaling or Rugosa cultivars, which makes them perfect for USDA zones 5 through 10.
