Yellow Monkeyflower (Erythranthe guttata)

Yellow monkeyflower is a highly variable species, most often growing as a herbaceous perennial, and sometimes as a self-seeding annual. It thrives in full sun and moist soil; the bright yellow, tubular flowers add a splash of colour to wet areas, and attract bees and hummingbirds. It can spread quickly through both seeds and rhizomes, often forming dense mats. Without ample moisture, the plants may die back in the heat of summer. Yellow monkeyflower is perfect for rain gardens, and for planting at the edges of water features.
