Forget-me-not, nomeolvides

Tiny flowers smaller than 0.5 cm in diameter. Forget-me-nots may be annual or perennial plants. Most have small, (1 cm diameter or less) flat, 5-lobed blue, pink or white flowers with yellow centers, growing on scorpioid cymes. They bloom in spring. Leaves are alternate. Popular in gardens, Forget-me-nots prefer moist habitats and where they are not native, they have escaped to wetlands and riverbanks. They can tolerate partial sun and shade.
