Bird’s Foot Trefoil, commonly known as Eggs and Bacon, is a resilient plant, often appearing uninvited in gardens, lawns, and disregarded spaces. It belongs to the legume family and is recognizable by its trifoliate leaves and small, golden-hued blossoms that emerge in the warm weeks of early summer.

The distinctive seed pods of this species curve gently, mirroring the appearance of a bird’s feet—a feature that gives the weed its name. Adaptable to various environments, Bird’s Foot Trefoil endures conditions of drought and partial shade, although it thrives best under the full glare of the sun.

Growth and Propagation:

  • Flourishes in diverse soil types
  • Expands swiftly through seeds
  • Capable of self-seeding in various landscapes

Effective Management Strategies:

  • Moist soil enhances the ease of hand-pulling
  • Regular lawn mowing impedes the plant’s seeding cycle
  • Bagging clippings is essential to prevent seed dispersion

Herbicide Application Tips:

  • Opt for glyphosate-based formulas in early spring, ahead of the flowering stage
  • Ensure the foliage is dry at the time of herbicide application

Identifying Weeds with Small Yellow Blooms

To recognize common weeds with small yellow flowers, examine characteristics such as leaf shape, plant height, flower structure, and growth patterns. Weeds such as Yellow Nutsedge and Yellow Sorrel may be identified by their distinctive yellow flowers and leaf formations.

Yellow Nutsedge is tall with grass-like leaves and golden-yellow flowers, while Yellow Sorrel shows heart-shaped leaves and cup-shaped flowers. Observing these details can help differentiate between various weeds.

Removing Yellow-Flowered Weeds from Lawns

Eliminating weeds from your yard requires a combination of manual, chemical, and cultural methods. Pulling weeds by hand or with tools can be effective for immediate removal.

Herbicides can be used for widespread infestations, but they should be chosen carefully to avoid harming desired plants. Maintaining a healthy lawn through proper mowing, watering, and fertilizing can discourage weed growth.

Prevalent Yellow-Flowered Weeds in California and Arizona

In California and Arizona, common weeds with yellow flowers include Dandelions, Broadleaf Plantain, and Spotted Catsear. You can often find these types thriving in local landscapes due to the region’s climate and soil conditions.

Distinguishing Features of Yellow-Flowered Weeds

Yellow-flowered weeds differ from other garden invaders by their vibrant flower color, often serving as a visual cue that facilitates pollination.

These weeds may also showcase unique growth habits and survival strategies, such as drought resistance or rapid seed dispersal, distinguishing them from green-flowered or non-flowering weeds.

Yellow Weeds’ Affinity for Roadsides

Weeds with yellow flowers are commonly found on roadsides and disturbed grounds because these areas offer open, unoccupied spaces with plenty of sunlight. The disturbed soil on roadsides is also ideal for these opportunistic plants to take root and spread.

Yellow Flowers in Grass and Weed Infestation

Yellow flowers in a lawn aren’t always indicative of a weed problem. Some flowering plants can coexist with grass without causing harm. However, persistent and aggressive yellow-flowered weeds should be addressed through removal and lawn care practices to prevent them from overtaking the grass.


In conclusion, while there are many different types of weeds with yellow flowers, dandelions are by far the most common. If you’re looking to identify a weed in your garden, chances are it’s a dandelion.

However, there are a few other types of yellow-flowering weeds that you should be aware of. These include plantain, chickweed, and ground ivy. If you’re unsure of what type of weed you’re dealing with, it’s always best to consult with a professional. A certified nursed or landscaper will be able to help you identify the weed and suggest the best course of action for removal.
