Plant of the Month: Spurge Laurel – Invasive in Canada but Not in the US?

This month, we’re taking a closer look at Spurge Laurel (Daphne laureola), a plant with a fascinating yet controversial profile. Known for its glossy evergreen leaves and fragrant yellowgreen flowers, Spurge Laurel has gained attention for its invasive tendencies in certain regions. Interestingly, while it’s considered a problematic invasive species in Canada, its status in the United States is less clear-cut. At Galaad Yard Care Services, we’re here to help you understand this plant, its impact, and what you can do if you encounter it in your garden.

What is Spurge Laurel?

Spurge Laurel is a small, shadetolerant shrub native to Europe and the Mediterranean. It’s often planted as an ornamental due to its attractive foliage and ability to thrive in challenging conditions. However, its invasive nature has made it a cause for concern in many areas, particularly in Canada.

Why is Spurge Laurel Invasive in Canada?

In Canada, especially in British Columbia, Spurge Laurel is classified as an invasive species. Here’s why it’s problematic:

Rapid Spread: The plant reproduces quickly through seeds, which are dispersed by birds and other wildlife.

Shade Tolerance: Unlike many native plants, Spurge Laurel thrives in shaded areas, allowing it to outcompete understory plants and dominate forest floors.

Toxicity: All parts of the plant are toxic to humans and animals, which deters natural predators and further aids its spread.

These characteristics have led to its designation as a noxious weed in many Canadian provinces, where it poses a threat to local ecosystems and biodiversity.

Is Spurge Laurel Invasive in the US?

In the United States, Spurge Laurel’s invasive status varies by region. While it has been reported in some states, such as Oregon and Washington, it hasn’t yet reached the same level of concern as in Canada. This difference may be due to variations in climate, ecosystems, and the plant’s distribution. However, gardeners in the US should still exercise caution, as its invasive potential could increase over time.

How to Identify Spurge Laurel

If you suspect Spurge Laurel is growing in your garden, here’s what to look for:

 Leaves: Glossy, dark green, and lanceshaped, arranged in a spiral pattern.

 Flowers: Small, yellowgreen, and fragrant, blooming in late winter to early spring.

 Fruit: Green berries that turn black as they mature.

 Height: Typically grows 2 to 4 feet tall.

What to Do if You Find Spurge Laurel

If you discover Spurge Laurel on your property, it’s important to act quickly to prevent its spread:

Manual Removal: Wear gloves and protective clothing to avoid skin contact with the toxic sap. Dig out the entire plant, including the roots.

Disposal: Place all plant material in a sealed bag and dispose of it in the trash. Do not compost or leave it on the ground, as it can regrow.

Monitor the Area: Regularly check the site for new growth and remove any seedlings promptly.

Alternatives to Spurge Laurel

If you’re looking for a similar plant that’s safe and noninvasive, consider these native or noninvasive alternatives:

Oregon Grape (Mahonia aquifolium): A native evergreen shrub with yellow flowers and blue berries.

Red Osier Dogwood (Cornus sericea): A hardy shrub with striking red stems and white berries.

Evergreen Huckleberry (Vaccinium ovatum): A native plant with glossy leaves and edible berries.

Why Choose Native Plants?

Planting native species offers numerous benefits:

Supports Local Wildlife: Native plants provide food and habitat for birds, pollinators, and other wildlife.

Low Maintenance: Adapted to local conditions, they require less water, fertilizer, and pest control.

Protects Ecosystems: Native plants help maintain biodiversity and prevent the spread of invasive species. (GYCS)
