  • Question

    Hi! I wanted to see if I can get confirmation on this plant. It's growing in a partially shaded flower bed in coastal Massachusetts and is located underneath where I had a bird feeder last summer. It's 6.5' tall, has both 3 lobed and 5 lobed simple leaves with small teeth, though younger leaves don't appear to be lobed. Big stem which appears to have small hairs. No flowers yet, though lots of spikes. Thank you for your help!

    Answer

    Dear jbasi, thank you for the nice array of quality images. Your plant is Ambrosia trifida (giant ragweed), a member of the Asteraceae. This is an early successional plant that is native to the United States. Best wishes.
