Plains Greasebush: A Hardy Native Shrub for Drought-Tolerant Gardens
If you’re searching for a tough-as-nails native plant that laughs in the face of drought, let me introduce you to plains greasebush (Glossopetalon spinescens var. planitierum). This unassuming shrub might not win any beauty contests, but it’s got character and resilience that can make it a valuable player in the right garden setting.
What is Plains Greasebush?
Plains greasebush is a perennial shrub native to the American Southwest and Great Plains. This hardy little fighter typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet tall, though most specimens remain much smaller. You might also see it listed under its former scientific names, including Forsellesia planitierum or Glossopetalon planitierum, but don’t let the name changes fool you – it’s the same resilient plant.
Where Does It Call Home?
This native shrub has claimed territory across four states: Colorado, New Mexico, Oklahoma, and Texas. It thrives in the high plains and desert regions where many other plants would throw in the towel. If you live in USDA hardiness zones 5-8 within this native range, you’re in prime plains greasebush territory.
