Thimbleberry

 Thimbleberry bush

Thimbleberry is a common sight in a redwood forest. It's a shrub with rounded deeply lobed leaves. Right now it's blooming.

Thimbleberry belongs to the Rose family, to which such plants as blackberry, raspberry and strawberry also belong. You can actually see some family resemblance.

It means that very soon we'll see some thimbleberry berries. Perhaps, thimbleberry pie?
