Care Guide

Watering

Blue-eyed Mary (Collinsia verna) should be watered about once or twice a week. It prefers regular but infrequent watering, allowing the top inch of soil to dry out between waterings. It is important to avoid over-watering to prevent root rot. If planted in full sun, make sure it doesn't dry out during periods of extended heat. In areas with hot summers, provide some shade from the direct sun and place the plant in a spot that gets morning sun but is shaded from the afternoon sun. Water deeply during occasional dry spells to supplement the normal weekly waterings.

Light

Blue-eyed Mary (Collinsia verna) thrives in full sun to part shade, with at least 6 hours of direct sunlight per day. Prefers moist, well-drained soils, but is capable of taking some dryness. While direct sunlight is preferred, it should not be left in direct sunlight for extended periods as its leaves tend to burn easily.
