Uneven yellowing in a clump April 15, 2004

Celandine found at a triangle of land that has been sprayed for four years. This is between Forest Glen and Dennis, next to the Trail and a dirt path upstream from the playground. May 5, 2007

An informative sign is attached by the Park to yellow and black pesticide signs. Glyphosate, in the widely available commercial product Rodeo, considered one of the least harmful herbicides. March 2004

Lawn mowers are of no help in lopping off seed heads; Only the top leaves are sheared. May 4, 2007

The brown patches in this lawn show where celandine grew before spraying two months earlier. (The property, which is park land, is in front of the corner house on the Parkway at Three Oaks Drive below Colesville.)

In 2004 it appeared that massive mats of celandine would develop in woods in the Kemp Mill area (along the old trail near Orebaugh, off Arcola) not far from the Wheaton Library. Sprayers in 2004-05 worked mainly near the path. By 2008 the celandine had indeed spread, but not as fast as it might have. In this photo at Kemp Mill, celandine grew abundantly, but only under the fallen branch. This must be circumstance - or was some animal eating the surrounding celandine? April 11, 2006
