There were some milkweed sprouts just appearing in Reiman Gardens south of Jack Trice Stadium, Iowa State University, Ames, on Tuesday, April 18. Of the nine species in the demonstration plot there, six of them, including Common Milkweed, had new sprouts less than ½ inch high, while the other three had not yet sprouted. The soil surface in this plot was mostly bare ground. Also had some common and swamp milkweed come up in the plot in front of the southwest corner of the Genetics Laboratory building on campus over the past weekend (April 22-23), and these are now (April 26) between 1 ½ to 3 inches high with the leaves starting to unfold – bare ground here also. In another nearby plot with prairie litter, also in front of the building near its southeast corner, none of the milkweeds are up yet.
