Vine · Thunbergia alata

A cheerful, well-mannered annual vine — not too big — that covers a mailbox post, small trellis, or hanging basket in nonstop orange, yellow, or cream flowers with dark centers all summer. Easy from seed, blooms until frost, and modern colors like 'African Sunset' are gorgeous terracotta-rose blends. Perfect where you want a vine but not a monster.
