’Abetwo’ is commonly sold under the trademark name of Incrediball®. It was developed from the Annabelle hydrangea, which was originally found in the wild near Anna, Illinois. 'Abetwo' typically grows 3 to 5 feet tall with a rounded habit. It has large flower heads, measuring 12 inches in diameter, which are held upright by thicker stems, even when soaked with rain. The blooms appear in early June and last for up to two months. The flowers open green, mature to white, and then finally fade to green again. The plant blooms on new growth, so a cold winter will not prevent it from blooming. The name Hydrangea comes from the Greek words hydo, meaning water, and aggeion, meaning vessel, in reference to the resemblance of the seed capsules to a small water pitcher.
