Shrubby Alkaliaster: A Hidden Gem for Southwestern Native Gardens
Meet the shrubby alkaliaster (Machaeranthera carnosa var. intricata), a delightful native perennial that’s been quietly thriving in the American Southwest long before any of us thought about xeriscaping. This unassuming member of the aster family packs a punch when it comes to drought tolerance and native garden appeal.
What Exactly Is Shrubby Alkaliaster?
Don’t let the scientific name intimidate you – shrubby alkaliaster is simply a hardy perennial herb that knows how to survive in tough conditions. As a forb (that’s garden-speak for a non-woody flowering plant), it stays relatively low to the ground while producing charming daisy-like blooms that’ll make you wonder why more people don’t know about this little treasure.
You might also see this plant listed under its synonyms: Aster intricatus, Bigelovia intricata, or Leucosyris carnosa var. intricata. Botanists love to shuffle names around, but don’t worry – it’s all the same resilient plant.
