Title: Plant identification from Prairie Village KS
Answered by: Barbara Medford
QUESTION:
My friend has identified this plant as a Horseweed. It is 3 1/2 to 4 feet tall. Has a thick, fuzzy single stem. Linear leaves, about 3/4 inch across and 3 or 4 inches long with one or two notches on each side, hang straight down overlapping tightly to the stem. Then there is that bushy top. The bushy top is tightly packed, many small flower stalks with very small leaves. The bloom is about 1/8 inch across, white, single row of petals with a pindot sized yellow center. I would very much like to attach my pictures, but do not see that option. A plant just 3 feet away is the exact duplicate of the Horseweed drawing on Pg. 88 of Field Guide to Wildflowers by Peterson and McKenny. This plant matches their illustration: 3 to 4' tall, single fuzzy stem has the more narrow, less long and less notched linear leaves which are spaced apart, growing straight out. The blossoms are on individually spaced flower stalks. Can you explain the difference? Is "bushy top" not a Horseweed?ANSWER:
We are sorry, but we are no longer able to accept pictures for plant identification. You can go to our Plant Identification page which has links to several websites that do accept pictures; you may be able to get more information from that.
On the plants in question: there are 3 members of the Conyza (horseweed, butterweed or fleabane) native to North America. Of those, two - Conyza canadensis (Canadian horseweed) and Conyza canadensis var. canadensis (Canadian horseweed) - are native to Kansas. Follow each link to our webpage on that plant. At the bottom of that page, under Additional Resources, you will find a link to Google. Click on that and you will get links to much more information, including pictures.
