(Thunbergia alata) Tender perennial grown as an
annual. Trumpet-shaped, 5-petaled tubular flowers
in a warm mix of yellows, oranges and golds.
Bearing 2-inch flowers with dark purple-black
throats, this East African native is showy trained
up a trellis, in hanging baskets, or in pots. Mature
plants grown in a frost-free environment may
climb 20 feet; expect 6- to 8-foot plants when
grown as an annual.
