Clerodendrum thomsoniae

Protected spots in frost-free zones, or indoor/outdoor potted plant. Native to West Africa. Restrained and mannerly growth to no more than 12 ft. Distinctly ribbed, oval, shiny dark green leaves, 4–7 in. long. Blooms from summer to fall, bearing flattish, 5-in. clusters of up to 20 flowers. White calyxes reminiscent of paper lanterns surround scarlet flowers, giving a striking two-tone contrast. Use it on sheltered patio walls or arbor posts. Grows well in large containers; move it to a frost-free shelter in winter.
