I have three of these plants. Two have this color of blossom. The third one has a paler color (see April 17th). This perennial is called by several names where I live: Geranium maculatum, wild geranium, and cranesbill geranium. It has a few other names too. It is native to the woodlands. It blooms in the spring through part of the summer. It is one of my favorite flowers this time of year. This is another plant I wish bloomed all throughout the growing season.
