Leafy Spurge plants are bright green, up to 2 feet tall, and form dense colonies from an extensive root system.  The juice is a milky latex and has caused poisoning in some livestock.  The plants bloom in early May to July and again in September depending upon the length of the growing season.  True blooming occurs about 10 days after the appearance of the yellow bracts.
