Shrubby False Mallow: A Little-Known Native Gem for Southwestern Gardens
If you’re looking to add some native charm to your southwestern garden, you might want to consider the shrubby false mallow (Malvastrum bicuspidatum). This unassuming little shrub may not be the showiest plant in the garden center, but it has some qualities that make it worth a second look for the right gardener.
What Exactly Is Shrubby False Mallow?
Shrubby false mallow is a perennial native plant that calls the American Southwest home. Scientifically known as Malvastrum bicuspidatum, this low-growing shrub typically stays under 1.5 feet tall, though it can occasionally reach up to 3 feet at maturity. Don’t let its modest size fool you – this little plant is perfectly adapted to life in challenging desert conditions.
The plant belongs to the mallow family, which means it’s related to hibiscus and cotton plants. Like its showier cousins, shrubby false mallow produces small, cheerful flowers that are typically orange to yellow in color.
Where Does It Grow Naturally?
Currently documented primarily in Arizona, shrubby false mallow is native to the lower 48 states and thrives in the challenging conditions of the American Southwest. This plant has evolved to handle the heat, drought, and intense sun that would send many garden plants running for cover.
