These spores come from native sensitive ferns that grow along the lake in loamy sand soils – in both full sun and partial shade. These ferns are a native wild ecotype and are cold hardy (our farm is zone 4a central Minnesota).
They are called sensitive ferns because the foliage dies back immediately with freezing temperatures. They fill in quickly in the spring and spread by rhizomes to provide a lush ground cover. They can and will share space with many other species. In Minnesota, they fade out in early October, leaving behind unique beaded fronds that stay standing all through the winter. These fronds make great decoration, wreaths, and vase fillers.
Spores will be contained within their original “seed balls” and may be attached to the stem.
