Calla lilies (Zantedeschia aethiopica) are native to the marshes and bogs in South Africa. These lilies enjoy moist areas in your garden. Callas typically grow 4 feet tall and produce trumpet-shaped flowers in white, maroon, green and yellow. More compact types are 24 to 36 inches tall. They require full sun and lots of water. Adding peat moss to the soil will help retain moisture around their roots. Flowers that go with calla lilies need to tolerate lots of moisture.
The iris is a hardy, long-living perennial that grows 8 to 38 inches from a rhizome. The rhizome is an underground root structure that stores food produced by the iris leaves and used for flower production. Flowers have six petals. Three petals are upright and three petals hang down. Blooms are blue, pink, purple, red, white, yellow and bi-colored in the spring. Some types of iris bloom again in the summer and fall.
Bacopas reach 3 to 6 inches tall when mature. This flower produces tiny blossoms that are lavender, pink, red and white starting in June and lasting through October.

Gerbera daisies are perennial daisies that produce blooms that are yellow, pink, peach and red on 12- to 18-inch stems.
