One of my top favourite plants is Hydrangea arborescens ‘Annabelle’. Super hardy, it has up to 10″ pure white heads. The heads start off lime, move through pure white and end up crispy pale browned. It has lime-ish coloured leaves, stays at 3-4′, and blooms on new wood. I had a river of them in my old garden and plan to create another flow of them up the slope once the rains start in the fall.
But, for now, I have inherited a few others:
Hydrangeas do really well in the PNW. They like shade, ok with a bit of drought, and the deer are staying away from my mature plants. The newbies need a bit of protecting it appears. The bonus is that the flowers dry really well and hold in there through the winter…on the plants or cut and brought into the house.
