Gardeners love Texas sage, also known as purple sage, for its very hardy nature. The plant can grow in all types of soil, is drought-resistant and has no pests, according to Texas A&M University. Gardeners also prize the sage for its lush leaves and purple, pink and white flowers. Although you can sometimes obtain pre-planted sage as seedlings or mature plants from a nursery, planting it yourself via seeds is often much more budget-friendly.
Choose a garden site. Texas sage thrives best in full sun but can handle limited amounts of shade, according to Texas A&M University.
Prepare the gardening area. Though the sage will grow in even poor soils, according to Texas A&M University, the plant will respond positively to amended soil. Use a spade to breakup the soil to a depth of 6 inches. Clemson University recommends stirring in a couple inches of compost, followed with a general all-purpose 10-10-10 fertilize applied at a rate of 1/2 lb. for every 50 square feet of gardening space.
Sow the Texas sage seeds. Bury the seed 3/4 inch deep and space the seeds apart by approximately 1 foot.
Water the gardening area twice daily or as necessary to keep the soil surface moist. The seeds will usually germinate within two weeks, according to Washington State University.
