Yellow-Flowered Weeds: The Vibrant Invaders of Your Garden

Common Yellow-Flowered Weeds

Dandelion

Dandelions are the most common yellow weed in lawns.

Identifying Features:

  • Fluffy seed heads that travel on the wind
  • Jagged leaves arranged in a rosette
  • A deep taproot that regrows if it breaks

Creeping Buttercup

This low-growing weed likes moist, poorly drained soil.

Watch Out For:

  • Shiny, cup-shaped yellow flowers
  • Spreads through seeds and underground runners
  • Thrives in wet, soggy conditions
