I love this plant! It forms a clean mound of velvety green foliage that remains attractive throughout the entire growing season. This highly adaptable plant will thrive in a range of growing conditions. While it is happiest in partial shade and moist soil it is also capable of thriving even in dense, dry shade. I have a beautiful, lush colony of Bigroot Geranium in evergreen shade under a pine tree in my garden, a site where I had struggled to get other plants to even survive.
In late spring/early summer it produces magenta-pink flowers that are held just above the foliage. The flowers mature into distinctive pointed seedheads (thought to resemble a crane’s bill – thus the common name of “Cranebill” for perennial geraniums as a group). When the seedheads open they propel the seeds skyward, sometimes to great distances. Thus, the plant increases by seed, as well as by rhizomatous rootstock, to slowly form large colonies. While it is a good increaser it is never in any way too aggressive.
The foliage emits a minty fragrance when crushed (historically this plant was valued for its oil content), which makes it immune to damage by deer, rabbits and even insect pests so the leaves remains pristine all summer. Once touched by frost in autumn the foliage takes on hues of red and orange.
For durability and all-season good looks in even the most inhospitable of shaded areas, Bigroot Geranium is a great choice. Height 12”-15”.
