Leafy Spurge


This plant has clusters of small yellow or greenish flowers at the end of thin stalks. The flower two large petals, appearing like a cup or disk below.

It is an invasive plant that’s made quite an impact in Colorado. This persistent weed spreads aggressively through its extensive root system, making it a tough competitor for native plants. The flowers contain a milky sap that can irritate the skin and eyes. Unfortunately, leafy spurge is not just a nuisance for gardeners; it also poses a significant threat to Colorado’s grasslands and prairies by outcompeting local flora and reducing biodiversity.
