Invasive plants and animals are a growing concern globally. The introduction or spread of invasive species threatens B.C.’s environment, the economy and society, including human health. In order to encourage public awareness and positive action against invasive species across the province, May has been officially proclaimed Invasive Species Action Month by the B.C. government. If action is taken, invasions can be prevented before they happen, and infestations can be controlled or eliminated, thus reducing their harmful impacts.

A low growing plant with attractive leaves
In hanging baskets and beneath shady trees.
Letting it spread will put your native plants in a squeeze!
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. But buyers beware: this plant will spread out of your baskets and along the ground, creeping into nearby forests and throughout your yard.
It 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 in the winter and is easy to spot this time of year in forested areas along the Valley Trail in Whistler, and around 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 micranthra) are especially showy, and do extremely well in containers.
