Abstract
A new rose plant cultivar intended for greenhouse culture for the production of cut flowers, distinguished by its uniform growth and cane quality with less blind wood, the exceptional vase life of its relatively slow opening flowers, when ready to cut, which makes them easier to handle in periods of high production, the exceptional timing characteristic and opening flower form of its deep red flowers, and the good response of this plant to lower temperature rose growing conditions.
