Ranunculus

The Persian buttercup (Ranunculus asiaticus) is technically a tuberous perennial, meaning it can survive for multiple years in ideal conditions. However, because they struggle in extreme cold or extreme heat, many gardeners in the US and Europe treat them as annuals. In warmer, Mediterranean-like climates, the tubers can successfully be left in the ground year-round.

Ranunculus thrives in USDA hardiness zones 8 through 11, where the winters are mild and the soil does not freeze. In these regions, you can plant the claw-like corms in the fall for spring blooms. In colder zones (3 through 7), they must be started indoors in late winter and planted out after the threat of frost has passed.

When properly cared for, cut ranunculus flowers can last in a vase for up to two weeks. To maximize their lifespan, you should cut the stems at a 45-degree angle and change the water every few days. Because of their dense, multilayered blooms, they are one of the most popular flowers in the global floristry trade.

Yes, ranunculus contains toxic compounds like protoanemonin, making them poisonous to both cats and dogs if ingested. Ingestion can cause symptoms such as drooling, vomiting, and diarrhea in household pets. It is highly recommended to keep these flowers out of reach of curious animals.
