Herb Robert

Meet Herb Robert

A lovely, little pink flower that is a member of the geranium family and profusely growing along the sides of the Chehalis Western Trail in Olympia, Washington.

One of the easiest ways to spot Herb Robert, even when it's not blooming, is by its leaf structure. The leaves, which usually grow in sets of three, have three to five rounded-toothed lobes. The leaf and flower stems are also covered with hairs.

The Herb Robert flowers bloom from May to October. Each flower has five petals, each with a distinctive fold or wave toward the center of the flower.


Herb Robert is a Class B Noxious Weed.

Why is it a noxious weed?

Herb Robert poses a threat to the forest understory and to plant biodiversity in forests of western Washington. It is capable of growing under full canopy closure in very dense populations and is considered a vigorous, plant. Where it occurs there appear to be fewer native herbaceous species.

Who would have ever guessed?
