The flower that you spotted is a favorite spring bulb of many. Anemone blanda is a species of flowering plant in the family Ranunculaceae, native to southeastern Europe, Turkey, Lebanon, and Syria. An herbaceous tuberous perennial, it grows to 15 cm tall and broad and all parts of it are poisonous, if ingested. It’s common name is Grecian Windflower. It comes in many colors such as pink, white and purple and tends to bloom in April or May. Given our cold spring this season they are, like many plants, a little late. They are usually planted in the fall and prefer part sun to full shade.
