  1. Bird’s Foot Trefoil (Lotus corniculatus)

Bird’s Foot Trefoil is a perennial weed that commonly grows in gardens or on lawns. It’s a tall plant that can be between three to five feet and blooms small yellow flowers.

As a hardy species, Bird’s Foot Trefoil thrives in any environment. It can tolerate drought and shade. However, it prefers moderately acidic soils with direct sunlight. 

This weed can help control erosion, yet it may take up space and hinder the growth of your own plants.

To avoid spreading Bird’s Foot Trefoil in your garden, you should clean up your gear and boots after hiking in the wilderness. You can also mow your lawn regularly and remove the clippings as thoroughly as possible

You can easily get rid of this weed by uprooting it from your moist soil. On the other hand, you might need to dig a bit into dry soil in order to remove the entire root. Remember to put the plant and its root away to prevent it from spreading any further.

The cypress spurge also goes by other names, such as Graveyard Weed, Bonaparte’s Crown, and Gaeyard Moss.
