Rainy Side Notes

Devil's club is a ginseng relative and notorious for its impaling spines. However it is worth cultivating in your garden, as it is a beautiful native shrub. After it flowers, it forms clusters of berries that are inedible by humans, but is a food source for bears. This shrub was at one time an important medicinal plant for coastal tribes.

In a Northwest garden, its maple-like leaves look tropical and can reach sizes up to 3 feet across, although most leaves will be smaller. I love this plant growing in a garden, but its spines are formidable. If you need a good barrier, this native will form an impenetrable one. Around its perimeter, you need to cultivate very cautiously, as you don't want to be impaled by one its spines.

In the wild, devil's club grows in shade near streams and seepage sites. In the garden, carefully site the plants in areas that are moist. If not, you will need to water them frequently during our annual dry spell. If you have a naturally shady, moist area this plant is a good selection for these wet conditions. If you already have devil's club growing, I believe it is too beautiful a plant to exorcise from your garden.
