Fun Facts
- 🌱 Texas cedar elm is native to the Edwards Plateau and south-central Texas, where it is sometimes called 'Scrub elm' and has been used as a windbreak and drought-tolerant shade tree for over a century.
- 🌱 Unlike most elms that are susceptible to Dutch elm disease, Texas cedar elm shows remarkable resistance to this devastating fungal pathogen, making it an excellent alternative to other elm species.
- 🌱 The tree produces flowers in late summer (August-September), unusual timing for elms, with seeds maturing and dispersing in fall—an adaptation to Texas's climate patterns.
