Nemesia strumosa

flower

Nemesia is a vibrant annual flower native to South Africa, prized for its brightly colored, orchid-like blooms in shades of red, pink, orange, yellow, and purple. These compact plants grow 12–24 inches tall and flower prolifically from spring through early summer, making them excellent choices for borders, containers, and hanging baskets. They prefer cooler temperatures and benefit from deadheading to encourage continuous blooms.
