Rosa

3-4' × same. A sport of FJ Grootendorst (Rosa rugosa x Mme. Norbert Lavavasseur) Netherlands, 1936.

Small lightly fragrant quarter-sized deep red blooms are fringed like carnations. Very unusual and attractive with a long bloom season, often going until frost. Holds up extremely well in the vase. Small foliage is deeper green than the standard Grootendorst. 

Upright arching yet compact vigorous form with prickly thorns. We think this little rose is quite cunning. Rugged, too. Ours survived bushhog and trampling horse hooves alike—we’ve since moved it to a safer spot on the farm. Looks great in a hedge next to a green shrub. The red really stands out from afar.  Zone 3. 

Grown using organic methods—not treated with synthetic fertilizers or chemical sprays.

Small Trees and Shrubs

As Green’s Nursery catalog from 1904 explains, “There are many trees that by pruning can be made to resemble shrubs, and many shrubs that by different pruning may be made to produce medium-sized trees.”

Roses Rosa spp.

Leaves, petals, hips and roots all have medicinal properties. Rose hips (fruits) are rich in vitamin C and make a wonderful “rose apple” jam; rose-petal elixir calms the nerves and lifts the spirit.

Each year, we aim to offer a diverse selection of unusual and antique varieties. Unlike hybrid tea roses, these roses are all vigorous, cold hardy and on their own roots. The antique varieties grow slowly compared to newer hybrids and tend to be more difficult to propagate. You may notice when you receive your order that some of these roses have small root systems and little top growth. Don’t be alarmed by this—it’s just the nature of these old varieties. We can attest that they perform just as well as the others. If roots are tangled, cut them back to 6" or so and spread them out in the planting hole.

Roses are native to temperate regions throughout the world.

Growing Roses

  • Soil: Well-drained soil with a good amount of organic matter.
  • Sun: Full sun, but some will tolerate part shade. Pick a site with good air flow, but avoid sites with cold northwest winds.
  • Spacing: 4–6' apart.
    • Sun: Full sun, but some will tolerate part shade. Pick a site with good air flow, but avoid sites with cold northwest winds.
  • Planting: Plant as early as soil can be worked. The roots of roses don’t spread beyond the original hole, so dig a bushel-sized hole, as deep as 2' or more. Mix soil with liberal quantities of well-rotted manure and compost. Add a coffee-can of rock phosphate or bone meal.
    • Prior to planting, prune plants back to 3–5 of the best canes.
    • Keep roses well mulched to retain moisture and reduce weeds. Add 2 shovelfuls of compost to each crown annually in late fall.
  • Pruning: Other than clipping out any dead wood, shrub roses and climbers require little pruning.
