Common garden weeds in the Yuba-Sutter area are usually non-native plants, but not necessarily classified as invasive weeds. To be classified as invasive, a weed must be shown to pose a serious threat to the survival of native species. Some weeds can pose a tremendous threat to your garden plants without actually posing much of a threat to native species, if the ecological niche they fill is a niche that exists mostly in gardens and that native plants wouldn't have thrived in anyway. This page lists plants that are common garden weeds but not classified as invasive species by the California Invasive Plant Council. All the plants listed on our invasive weeds page may also be common garden weeds, but to avoid redundancy, we will not reprint their names here.

Some people intentionally plant both common garden weeds and invasive weeds, due to the facts that weedy plants are easy to grow and some of them are pretty. It is a very bad idea to plant invasive weeds, because they are likely to kill off all your other plants, all your neighbors' plants, and all the plants in wildlife habitats for miles around. However, it is relatively acceptable to intentionally plant the common garden weeds listed below, because although they may still spread somewhat aggressively, they do not pose a major risk to wildlife habitats.

Annuals are generally weedier than perennials, which in turn are generally weedier than woody plants. The shorter a plant's lifespan is, the more rapidly it has to reproduce. The more rapidly a plant reproduces, the quicker it can take over an entire garden, killing all the other plants in sight. Fewer natives grow out of control than non-natives, because local ecosystems have evolved adaptations to keep natives in check. And certain plant families contain more weeds than others—in particular, the aster, mustard, carnation, goosefoot, pea, grass, and rose families contain significant numbers of plants that tend to be weedy in the Yuba-Sutter area.

Rough cockleburr (Xanthium strumarium) has taken over a large area across the levees from Marysville High School. After it dies off each fall, the spiny seeds dry and harden, clinging painfully to the clothes or fur of any people or animals who try to walk through it. Photo by queerbychoice.
