Fun Facts
- 🌱 Persian speedwell is sometimes called 'bird's-eye speedwell' because its pale center resembles a bird's eye watching you.
- 🌱 It is a winter annual in many regions, meaning it germinates in fall, overwinters, and flowers abundantly in early spring—making it one of the first flowers to bloom after winter.
- 🌱 The plant is self-fertile and prolific seed producer; a single plant can produce thousands of seeds, which is why it can become naturalized or weedy in favorable conditions.
