Dryopteris carthusiana (Spinulose Wood Fern) is a semi-evergreen fern forming a vase-like tuft of narrow, lacy, finely toothed, and dissected, bright lime-green fronds. The leaves are more intricate and lacy than those of many other ferns because of their complex structure and strongly toothed margins. Small, round sori develop on the undersides of the leaves during the summer. Their spores are distributed by the wind during late summer or fall. Well-behaved and non-invasive, Spinulose Wood Fern is an elegant species that is well suited to massing in a woodland garden where its fine-textured, lacy leaves can be admired. Evergreen in mild winter climates.
