Scutellaria mexicana, commonly known as Mexican Skullcap or Paperbag Bush, is a drought-deciduous shrub native to desert scrub and rocky slopes in the southwestern United States and northern Mexico, including the Mojave, Sonoran, and Chihuahuan Deserts. It typically grows up to 3 feet in height with a similar spread and has a rigid, branching pattern. The plant produces small, ovate leaves and is notable for its inflated, bag-like calyx lobes that persist after the flowers have faded, aiding in seed dispersal by wind. The flowers, which bloom from March to May, are less conspicuous, with purple to blue corollas that are attractive to pollinators such as bees.

Mexican Skullcap is valued for its unique appearance, particularly the ornamental calyx lobes that resemble small, paper bags. It is often used in xeriscaping and as an accent plant in rock gardens or desert landscapes due to its low water requirements and ability to thrive in poor, well-drained soils. It prefers full sun but can tolerate some light shade. While generally low-maintenance, it is important to avoid overwatering to prevent root rot. There are no major disease issues, but it can be prone to root rot if grown in poorly drained soils.CC BY-SA 4.0
