Are there palm trees in Dallas Texas?

There are two palms native to Texas. Sabal mexicana and sabal minor. Before being widely settled in the 18th and 19th centuries, the Lower Rio Grande River Valley had large groves of palm trees. A sanctuary containing some of these still exists. Be warned, some ill informed people believe all palm trees originated in Africa. If you see this kind of nonsense posted, recognize that you are dealing with someone who is ignorant of Texas plant life.
