Yellow Monkeyflower
Mimulus guttatus
Yellow Monkeyflower, also known as Seep Monkeyflower or Common Monkeyflower, is a herbaceous perennial that thrives in moist to wet environments such as streambanks, wet meadows, and pond edges. Typically growing to about 2 feet in height, this plant features light green, oval to lance-shaped leaves and produces an abundance of bright yellow flowers with some brown-red spots inside the throat. These blooms appear from late spring through summer, providing a long-lasting display of color. The flowers are particularly attractive to bees and hummingbirds, making Yellow Monkeyflower a valuable addition to any garden focused on supporting pollinator health.

Maintenance Tips
- Prefers consistently moist soil; ideal for areas that are naturally damp or have supplemental watering in dryer zones.
- Deadheading is not necessary but can encourage more blooms and maintain a tidy appearance.
- Thrives in wet, well-drained soils; intolerant of drought conditions but can adapt to temporary dry spells.
- Apply a layer of organic mulch to retain soil moisture and suppress weeds, particularly in warmer climates where the soil may dry out faster.
- Monitor for signs of mildew or other fungal diseases, which can occur in humid conditions. Ensure good air circulation and avoid overly dense planting.
