Tarrant City Zoning Code
APPENDIX TO APPENDIX A
CITY OF TARRANT APPROVED PLANTING MATERIALS
Required landscaping materials shall be from this list, and it is encouraged that native plant material be used. It is suggested, but not required, that materials used to meet the standards for plantings within open spaces be from this list; however, some native plants indicated with (†) may not be appropriate for other areas of a site. Plants listed on the current edition of Invasive Exotic Pest Plants shall not be accepted for compliance with landscaping requirements.
The materials marked with an asterisk (*) have been identified as materials that will tolerate drought stress better than most landscape plants.

Therefore, it is imperative that new plantings receive food follow-up care until they are established.
