For gardeners living in Mexico ad Texas, Louisiana and other states in the Deep South, gaura is an ideal plant for landscaping. The two most popular types of gaura, Whirling Butterfly and Siskiyou Pink, are prized for their striking spikey white and pink flowers. These beautiful perennials are also prized because they're so low-maintenance. When grown in their native habitat, they are disease-resistant and only require an occasional watering in the dry season.
Choose a site to plant gaura. Gaura essentially only needs ample sunlight to thrive. Once you have picked a spot you won't be able to change your mind--gaura sends down a lengthy tap root that makes it nearly impossible to transplant.
Prepare the soil. Gaura will grow anywhere except in poor-draining soil. If your chosen location often has standing water after a heavy rain, amend the soil with four inches of compost and plant your gauras in a raised bed.
Plant annual gaura plants after the first frost. (Perennials should be planted in the fall or right before the last frost.) Dig a hole that is slightly larger than the container the plant is in.
Carefully remove gaura from the container and put it in the hole so the top of the root ball is slightly above the surface of the soil. Adjacent plants should be at least two feet apart.
Water the soil thoroughly.
