A friend gave me some starts of the sensitive fern perhaps twelve years ago, and at first, I didn't think that any had survived. It showed up again, and has spread so thickly that I am going to have to thin it out in order to save my hostas and Solomon's seal. It is a very attractive fern, both the sterile and non-sterile fronds.

Native to much of North America and Asia, this fern gets its common name from its sensitivity to frosts, turning brown right away after experiencing frost. It is a fast spreading groundcover of bright green, coarse-textured fronds that are simply pinnate, not doubly pinnate as the typical fern. The fertile fronds bearing the spores are not leafy, but are brown stalks that bear clusters of bead-like structures on top. I've seen some wild colonies in the woods of French Creek State Park in southeast Pennsylvania.

We dug up a few of these ferns from my grandparent's yard, and planted them under a pine tree in our front yard last year. This year, they popped up in mid-May. I really like this fern. To me, it is so nice because it has such a different pattern than other ferns.

This fern can be grown both wet and in a regular garden. I have it mixed with other ferns in a moist sandy soil that is a bit of a south slope in shade. It also grow into a wet non draining container. It tend to develops long shallow rhizomes and then grows from one edge, like iris but much quicker. This can result into its popping up all over the place. The name Sensitve Fern comes from books that said it is sensitive to frosts but I can't really see much of a difference compare to other ferns.

This occurs naturally by springs in our meadow. It is robust enough to compete effectively with colonies of mint and raspberries and withstand regular trampling by deer. It is quite handsome to me, but my mother always called it "ragweed fern" and thought it looked like ragweed : ). I also use the dried fertile fronds in winter arrangements, but the infertile greenery wilts when picked--perhaps thats why its called "sensitive" fern. Our colonies have wet feet all summer but thrive in bright sun.

This very pretty fern travels by underground root. Colonies will spring up in shady locations or full sun, but if continually cut down will eventually die off where cut and travel onward as long as they have abundant moisture.

This fern is wonderful in a woodland setting or at the perimeter of a field, but it does have an invasive nature and once in your garden, will travel and pop up all over - creating a nuisance. We have colonies of these that started in our hillside garden years ago, and when pulled, cut or generally weeded out, have traveled down now to the rocks at the base of the garden. If I dig down in the rocks slightly, I can find the long rootstock that keeps this traveler going. I almost hate to pull them as they are a very pretty fern.

One of the nicest wild ferns in this area. It grows happily even in full sun if it has enough water, and large stands of them can be seen along roadside ditches.

I've transplanted this fern from the wild with great success, but one of my biggest surprises was the first one I ever relocated. It was a tiny little thing, only 3 or 4 inches tall....needless to say, it got a new home before the summer was through.

I like the fruit stalks with the spores for flower arrangements too. They have a lovely cinnamon color when they are mature.

This plant is comfortable and frequent enough up here in New England to leave its natural boggy habitat and grow happily in the woods.

I use the spore-bearing frond in dried flower arrangements.

This is a common fern in the pine savannahs of Louisiana and Mississippi. It's really quite elegant, both in the wild and in my garden.

This is a native fern here in Missouri, although not very commonly seen. It needs consistently moist soil to look good, but the rhizomes can withstand dry spells and will make new foliage when the rain returns. It does well in boggy places. I put some in a moist flower bed and just dug out buckets of it this fall. It makes runners all through other plants, so I recommend that you put it in a natural setting, not in a formal bed. It has a soft green color in the shade, more yellowish in full sun. It reaches heights of 30 inches with adequate moisture. The spores are located on separate, fertile fronds that appear in late summer and fall. I have seen a few plants that have come from spores here. The foliage is rather coarse, not fine like other ferns. The best use of this plant that I have... read more
