Up on the cliff next to the stairs to the upper garden there is a beautiful plant that hosts lovely white flowers each spring. I discovered it is a wild Mock Orange (Philadelphus lewisii).
It's a deciduous shrub that's native to western North America and grows from northwestern California to southern British Columbia. You'll also find it in gardens as well.
Mock Orange grows from 1.5 to 3 metres tall with pointed, egg-shaped leaves. In early May, small white flowers with yellow stamens brighten up the countryside.
In late June, round red to brown fruits appear. Because they are an early food source, birds such as Cedar Waxwings take advantage of their availability. -- Margy
