Yellow Lamium (or Yellow archangel) is often sold in hanging baskets or planters because it spreads fast, is shade-tolerant, and has attractive looking leaves. Buyers beware, this plant will spread out of your baskets and along the ground, creeping into nearby forests and throughout your yard.
Lamium sends down roots every few inches, and re-grows easily after you have pulled it out, making it extremely difficult to remove. It does not die back in the winter and is easy to spot in forested areas along the Valley Trail in Whistler, and in the Garibaldi Highlands in Squamish, where it has crept under people’s fences and is smothering the low-growing native vegetation.
There are many other attractive shade-tolerant native plants that can be planted instead of Yellow Lamium. Native Coral Bells (Heuchera) are especially showy, and do extremely well in containers. You can check out PlantWise’s “Grow Me Instead” list of plants here for plant ideas that aren’t invasive and look just as good in your garden.
