How to Grow Gilia tricolor
Overview
Gilia tricolor, also known as blue-eyed Mary, is a charming annual flowering plant that adds a pop of color to any garden. With its vibrant purple, white, and yellow flowers, this member of the phlox family (Polemoniaceae) is sure to brighten up your outdoor space.
Growing Conditions
Gilia tricolor thrives in full sun and well-draining soil. It prefers cooler temperatures, growing best in zones 4-8. This plant is drought-tolerant once established but blooms most prolifically with regular watering.
Planting & Care
Sow Gilia tricolor seeds directly into the garden after the last frost date. The seeds require warmth to germinate, so patience is key. Water regularly and mulch around the base of the plants to conserve moisture and suppress weeds. Deadhead spent blooms to encourage continuous flowering.
Common Problems
Gilia tricolor is generally a low-maintenance plant, but watch for slug damage in early growth stages. If the soil is too rich or watered too much, this annual may become prone to flopping over due to lush foliage. Adjust your watering and fertilizing practices accordingly.
Harvest or Enjoy
Harvesting Gilia tricolor's flowers is purely for enjoyment, as they are not commonly used in cooking or preservation. Instead, simply enjoy the plant's beautiful blooms from late spring through early summer, and let the seedheads provide food for birds when the growing season concludes.
