Rod Simmons led a plant walk May 27, 2006, through Leakin Park, located just inside the Baltimore City line. While we looked for species of Carex to identify, we treked through this section of the forest where a huge expanse of hillside above and below us was carpeted almost entirely with Vinca minor, otherwise known as Periwinkle. This plant is commonly sold in garden centers as a groundcover, and cover the ground it does very well, as you can see from these photos.
