Available in a myriad of shapes and colors, caladiums are a top pick for shady garden beds or containers. Their bold, tropical foliage looks terrific from early summer until frost. Caladiums grow from tubers planted just underneath the surface of the soil. Standard caladium varieties grow 18-24 inches tall; dwarfs grow 8-12 inches tall.
For the best effect, always plant caladiums in clumps or drifts. They look spectacular and help support each other in high winds. Here, a mixed group of pink, white, and green caladiums is paired with another shade lover, browallia ‘Endless Illumination’.
Bold and beautiful! That’s how most gardeners describe the brilliant, oversize leaves of cannas. These tropical beauties are available with green, bronze, black, variegated, or striped foliage. As a bonus, they also develop flowers in red, pink, orange, yellow, or bicolor. Cannas are tropical and prefer a hot, sunny spot in the garden. Start them from rhizomes planted directly in your garden after frost danger has passed.

Standard-size cannas can grow 6 feet tall; their large, paddle-shape leaves will block any view. Here, a clump of Tropicanna canna edges an asphalt driveway. Dwarf cannas, which grow 2-4 feet tall, are a good choice for smaller lots.
Once only a shade plant, new varieties of coleus have been developed to grow as well in the sun as they do in the shade. Coleus comes in a mind-boggling array of solid and mixed colors.

For almost instant color you can’t beat hyacinth bean vine, Dolichos lablab. This annual vine grows quickly from seed sown directly in the garden after frost danger has passed. The vine forms a wall of dark purple foliage that’s topped with purple seedpods and pink-purple flowers. It’s a sun-lover, so plant where it will receive 6-8 hours of direct sunlight per day.
Because it's a vigorous vine, hyacinth bean vine requires a sturdy fence or trellis to grow on. Sow the seeds about 6 inches away from the base of the support and stand back. It won't be long before the entire structure is awash in purple. The vines produce beans that can be toxic unless they are prepared properly. To be safe, use hyacinth bean vine as an ornamental plant only.
