Salal, a summer beauty

In the midst of our dry NW summer, while many plants look worse for wear, our native evergreen Salal shrubs, Gaultheria shallon, are shiny and healthy. Salal flowers in the spring with pinkish-white bell-shaped flowers in groups of 5-15 on racemes; very similar to the Pieris japonica flower. Both plants are in the Ericacea family. The Salal shrub can grown to 16′ tall and forms a dense mass that creates habitat and food for local birds and animals.

Looking for Autumn Color

I walked through the arboretum this week looking for early fall color in the park. This Fothergilla major always seems to be one of our first color transformations and its brilliant  reds and oranges drew me to it as usual.
The Fothergilla major is a deciduous shrub native to the Southeastern U.S. where its common name is Witch Alder. Though not an alder, it is in the Hamamelidaceae family and, like its relative Witch Hazel, is a wonderful deciduous shrub for any garden.
