Hydrangea arborescens 'Abetwo' is also know as Hydrangea arborescens Strong Annabelle as well as Hydrangea arborescens Incrediball. A recently introduced variety, 'Abetwo' has eyecatching large ball-shaped flowers (up to 30cm in diameter) over an extended period from mid to later summer. It is noted for having particularly strong stems, so does not flop over as with many Hydrangea. Flowers June-September. Height 150-200cm. Supplied in a 3 litre pot.
