An evergreen hydrangea?!! You betcha!
There are very few evergreen vines for gardeners in the Pacific Northwest, but this gorgeous gem from Asia is becoming more readily available and it’s simply one of the coolest flowers you’ll ever get to witness opening.
From plump, peony-like buds, they begin to slowly crack open, a froth of fertile flowers begin to form and over the course of a few days, a flat umbel “lacecap” begins to form.
When visiting the Washington Park Arboretum on a regular basis, it is usually not evident that changes occur in both the plants themselves as well as the land forms. However it is easy to see when you compare the photographs over a period of years. This is particularly true when there is water movement involved.
This summer, there will be a new garden constructed near the large southern-most pond along Azalea Way.
