Vanilla Leaf (Achlys triphylla) is now in full bloom. This distinctive forest-floor plant has leaves with three leaflets that arise directly from underground stems. Its tiny, white flowers arise in dense spikes from those same underground stems.

As its name implies, the leaves of this plant have a faint scent vaguely resembling vanilla. The odor becomes stronger if you gather a bunch of leaves and let them hang upside down to dry. In fact, I personally am not able to discern any vanilla odor from this plant unless its leaves are dried. For many years, it was a mystery to me why this plant has the common name it does.

Bundles of such dried leaves can be hung near doors and windows as an insect repellent; they have been used as such since pre-contact days by Native Americans. I have not personally tried it yet, but it is also reported that rubbing the fresh leaves on exposed skin can also act as an insect repellent.

You may be surprised to learn that this plant is a close relative the Oregon-Grape (Mahonia spp.). Both are in the barbarry family, Berberidaceae.
