Be on the lookout; it's quite easy to see from your car along roadsides right now. It has yellow-green flat-topped flowers on upright plants about 30-36 inches tall. It reminds me of a yellowish Queen Anne's lace although up close the leaves are quite different.
Your skin needs to come into contact with the leaves and then be exposed to sunlight for the reaction to occur. Be especially careful when weed-whacking or using a push-mower. Wear long pants and long sleeves when working near this plant. Regular mowing will keep it in check but it reproduces by seed so it will keep coming back. For more information call our office or visit our Web site to see a picture.
