Plant of the Month: Lindheimer’s Morning Glory
Lindheimer’s Morning Glory is a long blooming, perennial vine of Central and West Texas. It is related to the commonly cultivated Morning Glory species from tropical regions of the Americas, generally grown as annuals in our area. Our native species is more cold hardy, and grows as a deciduous perennial vine. It likes full sun, and although it is generally tolerant of dry conditions it responds well to supplemental water during droughts.
Lindheimer’s Morning Glory has 2″ to 3″ faintly fragrant sky blue flowers from April through October. Like other Morning Glories, they open in the morning and close by mid-day. The vine can grow to 6′ and is trailing or climbing depending on where it is grown. In its native habitat it is found in rocky soils, in draws or ravines. Because deer will eat the foliage, it may be found growing among other protective plants where deer are present.
Plants may be found in nurseries that specialize in natives and are worth seeking out. The seed can be hard to find commercially, but it can readily be grown from collected seeds. Plants started from seed will generally bloom the second season.
2016 marks the 215th anniversary of Ferdinand Lindheimer’s birth in 1801. Lindheimer, an early resident of New Braunfels, is known as the ‘Father of Texas Botany.’ He collected many specimen of previously unknown plants in Central Texas, and today over 40 plants bear his name.
