Cornflower
Centaurea cyanus
Yes—rabbits and guinea pigs can have a few unsprayed cornflower petals (Centaurea cyanus, also called bachelor's button) as an occasional flower treat once hay is going down normally. Keep the serving small—one bloom or a pinch of petals—so extras do not loosen stool. Chinchillas need even less room for flower snacks; many owners skip them altogether. Skip dyed florist mixes and anything that may have been sprayed.

Is Cornflower item toxic?
Centaurea cyanus is widely listed as non-toxic for rabbits in treat-sized amounts (House Rabbit Society includes cornflower / bachelor's button on safe flower lists). It is not a classic poison, but sprayed or dyed blooms are unsafe. Safer bias still means tiny portions only—not free-choice forage.
Should I feed my pet Cornflower?
Yes—unsprayed cornflower petals can be an occasional treat for rabbits and guinea pigs. Keep portions tiny, and be extra cautious with chinchillas.
How much can I feed them?
Offer a few petals or one small bloom, no more than once or twice a week. Introduce slowly, stop if stool softens, and keep unlimited grass hay as the main meal.
