Wildflower Bloom Report

Spring Wildflower Season Ending as Summer Nears

Posted on 5/15/2015 by State Nature Preserves

We’ve had an absolutely fantastic spring wildflower season across Ohio. While the height of the season has passed, there are still many wildflowers to see throughout May. Here are a few things to seek out around the state this weekend.


Mid to late May is when umbrella and bigleaf magnolias bloom at Lake Katharine. These large-leaved trees produce beautiful creamy white flowers. The Pine Ridge and Salt Creek loop trails are the best places to see umbrella magnolia. Spotting bigleaf magnolia takes a keen eye as it is further from the trail, but it can also be viewed from the Pine Ridge trail. Synandra, a member of the mint family often mistaken for an orchid is entering peak bloom at Shoemaker. Throughout southern Ohio, other late spring wildflowers you may encounter now include Virginia spiderwort, golden Alexanders, and Indian cucumber.


We’ve been seeing wonderful photographs of both Virginia and appendaged waterleaf taken around central Ohio. The tiny Canada mayflower is blooming in the Hocking Hills area. If you haven’t yet seen showy orchis or pink lady’s-slipper, be sure to seek them out this weekend as they will soon be gone. To learn more about our late spring wildflowers, join us at Conkles Hollow on Saturday, May 16, from 10 a.m. to 1 p.m. for a wildflower hike.


Wild Columbine is now blooming in northern Ohio, a sure sign that the trilliums are now past peak in the north. Wild geranium is putting on a show at Lawrence Woods. Redbud, wild blue phlox, blackhaw, and showy orchis are now in bloom at Goll Woods. The federally threatened Lakeside Daisy continues to impress on the Marblehead Peninsula. Our Lakeside Daisy open house will be held Saturday, May 16, from 1 p.m. to 5 p.m., just in time for the peak bloom. In the Oak Openings of Toledo, the beautiful common lupine and hoary puccoon will be reaching peak bloom this upcoming week at Lou Campbell. If you’ve missed seeing trilliums, head to the furthest northeast portion of the state. Large white and red trilliums are still blooming there, but they too will soon fade.

We hope you have enjoyed our inaugural weekly spring wildflower bloom reports. While the season is ending and this is our last report, an array of wildflowers will continue to bloom throughout the summer and into the fall. We encourage you to take wildflower photos throughout the growing season and upload them to social media using the hashtag, #ohiowildflowers.
