Southwestern Mock Vervain (Glandularia gooddingii) exists as a native annual plant in southwestern United States regions, together with northern Mexico regions, where it survives as a drought-resistant plant. This plant displays small lavender flowers along with purple flowers, which mostly bloom during springtime and after rainfall events. Southwestern Mock Vervain grows as soft green mounds featuring deeply fixed leaves which spread across open desert areas and rocky ground.
The extended bloom time of this plant makes it attractive to butterflies, along with several types of pollinators. The plant performs best when grown in complete sun exposure combined with dry, well-draining soils, which allows it to succeed in xeriscapes and desert gardens. The low-maintenance Southwestern Mock Vervain shows strong resistance to heat conditions, followed by solid tolerance to poor soils and minimal water requirements. The small dimensions of this plant create an elegant appearance, which sets against its powerful capability to survive arid climates with minimal maintenance requirements.
