Common Questions
Yellow Blue-eyed Grass questions
What zones can Yellow Blue-eyed Grass grow in?
Yellow Blue-eyed Grass is hardy in USDA Zones 4–9. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Yellow Blue-eyed Grass deer resistant?
Not reliably. Deer may browse Yellow Blue-eyed Grass, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Yellow Blue-eyed Grass bloom?

Does Yellow Blue-eyed Grass need full sun?
Yellow Blue-eyed Grass does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
