John Cabot Explorer Rose

Rosa x Hybrida 'John Cabot'

Description:

A rose bush with beautiful neon pink rosette flowers and light orange rose hips (seed pods). Leaves are thin, waxy and oblong with a pointed end. The leaves also seem to grow adjacent to each other, rather than alternating. The Leaves range from a light green to a darker green. Multiple thick thorns also protrude from the thicker stems, along with really thin, fine thorns, scattered throughout the bush.

Habitat:

One of the hardiest rose shrubs. Hardy to zone 2b. Requires full sun and a well-draining soil.

Notes:

General look of the rose bush appears healthy. Looks as if it is getting ready for winter, dropping it's leaves. A few flowers left on some branches. It's bark and stems have no apparent problems. However, one branch is showing signs of concern. The majority of the leaves on this branch have multiple black spots on them. A few leaves are even completely black. This could be caused simply because of the cold temperatures, but I would imagine the leaves would change to be a more autumnal colour such as brown, yellow, orange or red, rather than just black and spotty. The branch affected is also closer to the ground than any of the other branches, so perhaps the problem is fungal? Black spot comes to mind when it comes to roses, but I am uncertain of whether or not this is the issue. If blackspot is the issue though, then the fungus Diplocarpon rosae is more than likely the culprit.
