‘Blanc Double de Coubert’ Hedgehog rose

Rosa 'Blanc Double de Coubert'

ROE-sah Audio
Rosa 'Blanc Double de Coubert'

The white of this rose has a purity of color that is without equal. It produces semi-double, very fragrant flowers from spring to fall, which are sometimes followed by orange hips. It grows to 6 feet high and wide.

Noteworthy CharacteristicsRugosa roses have thorny branches and attractive, distinctively wrinkled leaves. (The species takes its name from the Latin word rugosus , meaning "full of wrinkles"). They grow well in mixed borders, hedges, and as specimens, and are tolerant of harsh conditions, including salt spray, wind, and poor soil. 

CareGrow in fertile, moist, well-drained soil in full sun or partial shade. Provide good air circulation and remove fallen leaves to help prevent disease. In late winter or early spring, prune lightly or back by up to 1/3, reducing side shoots by 1/2 to 1/3. To renovate, prune one in four or five shoots from the base.

PropagationTake softwood cuttings when bloom initiates in spring to summer; take hardwood cuttings in fall.

    Can you cut the flowers off to put in a vase on the table?

    I have this rose, planted early last 2015 growing season and here it is the final day of June 2016 and it has yet to bloom. Its getting some good outward growth, not much up and definitely no blooms. I've fed it, cared for it and planted it in a great spot. What could be wrong?

      If you fed it with a high Nitrogen fertilizer, you've stimulated vegetative(green, leafy) growth at the expense of bloom set. A root stimulator(Like Fertilome 4-10-3) or blooming and rooting food would be preferable. It will bloom it's head off once it gets going :-)

        Thank you very much. That might just be the cause I do see what appear to be buds, but I could be wrong, could be more leaf growth! lol I'll have to look into getting a different fert!

    We love our Blanc Double De Coubert, but it is spreading into some other areas. We were able to dig up part of it to transplant, but we had to just cut a lot of it off at the ground since it was growing under our sidewalk. I put those cuttings in water. Is there a chance they will root so I can plant them also?
