Abstract
A new and distinct variety of Hybrid Tea rose plant is provided that abundantly forms attractive double flowers which are greenish-white at the bud stage and finish to white when completely open. This blossom coloration is believed to be unique for this class of rose. The buds are very long. Such flowers exhibit a good vase life and possess petals that detach cleanly. The plant exhibits a bushy growth habit, forms long straight stems, forms semi-vigorous vegetation, and is particularly well suited for greenhouse forcing for cut flower production. Additionally, the plant is resistant to diseases when grown under greenhouse conditions.
