I've had my 2 bushes for about 4 years and they are averaging about 4 feet high and wide now. Blooms aren't basketball sized like they advertise but are pretty big. Blooms all summer from about June-July and until frost. My bushes receive no fertilizer and get hot afternoon sun and just keep on blooming and growing. Lots of insects enjoy feasting on the blooms also.

This is a new cultivar that was patented in December 2009. It has the largest flower heads of any of this species, which are at least 12 inches wide and a little more. Its flower heads have 4 times as many of the all sterile florets as the old common cultivar of 'Annabelle.' It has very thick stems so that the big flower heads don't flop over in the rain or with just with time. It is offered by the large nursery company of Proven Winners and I have been seeing it getting planted around. I, myself, find this cultivar to be "gaudy" with such huge flower heads. One person reported it as being liked by pollinating insects, but I don't see any of the tiny, fertile florets on this cultivar, so I don't believe any pollinating insect are really visiting this. I did not see any insects when I took a photo of three plants in a parkway island.

Hydrangea arborescens 'Abetwo' was developed (pp20571, 2009) by Timothy D. Wood  from Spring Meadow Nursery of Grand Haven, Michigan. 'Abetwo' originated from an open pollination of 'Annabelle' (parent) and an unknown H. arborescens in 2002. Compared to Hydrangea 'Annabelle', it is taller, has larger flower heads, and thicker stems that do not splay when wet. The flowers start out lime green and mature to pure white. Blooms in early June for ~ two months.
