When you go to the nursery or local greenhouse to buy plants or purchase a seed mixture, you usually don’t expect to bring home an invasive species that is going to take over your yard as well as your neighbors’. While nurseries and greenhouses are usually less risky than buying a seed mix from a national retailer, you may still pick up a noxious weed that is a popular ornamental.
Noxious weeds that are commonly sold as ornamentals include: dame’s rocket, yellow and Dalmatian toadflax, oxeye daisy, myrtle spurge and Chinese clematis. Some of these plants may also be confused with native plants or noninvasive, introduced species.
Shasta daisy is a popular ornamental that is often mistaken for oxeye daisy. In comparison, Shasta daisy is a larger and more robust plant, but to an untrained eye, there are few other differences.
What makes one plant invasive versus a safe choice for your garden? Shasta daisy forms a root ball and does not spread via underground rhizomes. Oxeye daisy does and is capable of escaping a planter and creeping across your lawn and down the right of way to infest the whole subdivision.
As a landowner, you are responsible for managing noxious weeds on your property according to the Colorado Noxious Weed Act Title 35 Article 5.5. Before planting a flower bed or landscaping, make sure you are familiar with the Colorado Noxious Weed List. Not only will it prevent you from planting an illegal species, it will save you time and money in the long run.
If you have planted a noxious weed by mistake, that doesn’t mean you have to tear it out of your garden or treat it with herbicides. If it hasn’t spread out of the planter to your neighbor’s yard, etc., simply clip the flowering heads and bag and burn them or take them to the landfill to prevent seed spread. If you planted a noxious weed that spreads by its roots as well, create a border using garden edging that creates a barrier deeper than the roots penetrate. If you notice that they are spreading, research the life cycle of the plant to determine which treatment method will be the most effective or contact the County Weed and Pest or Colorado State University (CSU) Extension office.
Prevention is much easier than controlling a noxious weed population and will save the homeowner from a lot of headaches.
Archuleta County Weed and Pest is your local resource for managing noxious weed populations and controlling other pests.
