Hydrangea arborescens 'SMNHRL' (SUBLIME ANNABELLE®) is the latest addition to the Proven Winners® Hydrangea arborescens range. SUBLIME ANNABELLE® has very large flowers that change from light to dark lime green, with a striking pink center in the heart of the flower. The flowers are highly resistant to heat and intense sunlight, allowing them to retain their beautiful color until autumn. SUBLIME ANNABELLE® has very strong stems. The dark green leaves contrast beautifully with the lime-green flowers. The flowers are also very suitable as cut flowers. The plant was bred by Tim Wood in Grand Haven, Michigan (USA), and plant breeders' rights have been applied for. Valkplant B.V. from Hazerswoude and Spring Meadow Nursery Inc. from Grand Haven are marketing the plant. Valkplant B.V. has submitted it for the novelty inspection.
