Vanilla Leaf is a deceptively robust plant, spreading via rhizomes just under the soil surface. I've planted it a couple of times since this first patch, always assuming it wasn't coming back each year. It doesn't arrive late, it just looks so delicate to me. It reminds me of Jeffersonia diphylla, an eastern native that is also growing in my garden.
My Encyclopedia of Northwest Native Plants for Gardens and Landscapes, by Kathleen A. Robson, Alice Richter and Marianne Filbert says of Vanilla Leaf: "Plants apread slowly but once established form a luxuriant ground cover. This species is a graceful addition to the shady woodland garden, pond, or stream margin but does poorly in containers."
The Plants for a Future website says that the flowers are hermaphroditic, having both male and female parts, and are self-pollinated by wind. I've seen photos online of seed capsules that form on the flower, but I've never found any on mine. Native Americans used it to treat tuberculosis and cataracts, as a hair wash, and as an emetic, which leads me to believe that using it to make tea as recommended by some websites is possibly not the best idea. Native Americans also hung the leaves to dry in order to repel flies and mosquitoes.
When dried, the leaves smell of vanilla, hence the common name. It is also called Sweet-after-Death. It is found in the wild along the western side of North America, from British Columbia to northwest California. See its distribution range here. Like other PNW natives, it is well-adapted to our wet fall/winter/spring and dry summer.
Mine is growing far in the back Northeast corner of the garden, in a shady woodland area under some Douglas firs. The area also harbors PNW native shrubs such as Elderberry, Vine Maples, Ocean Spray, Red Osier Dogwood, and Ninebark, as well as other perennials native to the PNW, such as Trillium ovatum, Bleeding Heart, Columbine, Maidenhair fern, Shooting Stars, and Fawn Lily. Also weeds. Lots of weeds.
