Notes:
According to the US Patent for this rose, DELverbla is a Hybrid Tea that forms double flowers which are greenish-white at the bud stage and finish to white when completely open. This rose is particularly well-suited for greenhouse forcing for cut flower production. The breeder crossed 'Crystalline' (ARObipy) with 'Tineke' and from that cross DELverbla was one of fifty-four plantlets obtained. It can be readily distinguished from other varieties including the parent varieties in that DELverbla forms buds that are more blunt and flowers that contain more green than either parent. It also possesses more flower petals than 'Crystalline'. It exhibits long and straight stems, rigid and straight peduncles, a good ability to be forced under greenhouse conditions, and a long vase life for its distinctive green-white blossoms. Flowers appear either singly or up to four per stem.
