Sensitive fern is a large, somewhat coarse deciduous fern that occurs in wet woods and thickets and in moist soils along streams and springs. Grows up to 4′ tall, featuring long-stalked, bright green, fronds. Commonly called ... sensitive fern because the green vegetative fronds are very sensitive to and suffer almost immediate damage from the first fall frost. One of the few ferns that can tolerate full sun conditions if wet enough. Although native to marshy areas, it grows quite well in average garden soil as long as it is not allowed to dry out. Spreads by both creeping rhizomes and spores, so it can be quite assertive with the right growing conditions.
