| Hydrangea arborescens 'Haas Halo'. Yes, this is MY plant! |
In 2013-14 Plants Nouveau group helped introduce to the market a new naturally-occurring sport of hydrangea arborescens that was found in eastern PA, called 'Haas Halo'. As with most plants of this species, it grows to about five feet tall and can expand more or less infinitely via sucker shoots that appear in the soil yearly. The foliage color is the same as most plants of this species, and flower heads can be best described as a lacecap version of Proven Winners' Incrediball. More specifically, each head can get up to about the size of a dinner plate and features a small number of sterile florets around and interlacing with a large number of fertile florets. Since there are a low number of sterile florets in each flower head, the plant is very flop resistant during heavy rain storms!
