Ambrosia (Chenopodium botrys) Annual. This plant is also known as Jerusalem Oak and goosefoot. It's scent is delicious, so much so you'll want to eat it. According to the USDA, it is edible and I've heard it makes good tea. I have yet to try it. The plant itself grows to about 2' with the bulk of the plant being the flower head. Mine always grow small. I think it is because of where I have them. It is often dry and may be too dry to provide maximum growth. It needs full sun, water when dry, and fairly decent soil. Good fertility will make it grow to it's full potential. Great for pot pourrie, putting in swags and wreathes, Victorian theme gardens, cottage gardens, or just to have a pot on the windowsill.
