Growing in North Texas
Dwarf Mexican petunia has been named a Texas Superstar™ by Texas A&M University. The plants are adaptable to various soils and growing conditions. Although they prefer full sun, the plants survive in partial shade although with less flowering. Once established, Mexican petunias are drought-tolerant. Some supplemental water is required during periods of drought. Cut dead foliage to the ground after the first hard freeze and leaves will re-emerge from roots in spring.
Warning: Spreads rapidly.
