Netted chain ferns

Netted chain fern: sterile fronds.

The netted chain fern (Woodwardia areolata) is native to eastern North America including most of Florida. It spreads via rhizomes and acts as a ground cover in partially shaded areas with some moisture. 

Leaves or fronds are dimorphic with the sterile leaves being flat and relatively broad for a fern, while the fertile fronds (those bearing the spores in structures called sori. (Sorus is the singular.)) are taller and have very little green leafy area. For this fern, sori are oblong and are arranged in neat lines, this is the characteristic that gives the chain ferns their name. In North Florida and in more northerly areas in its range, the green sterile fronds die back in the winter, while the fertile fronds persist through the winter.

The hand of the gardener in native landscapes

Plant more natives!

In 2013, a volunteer beautyberry shrub near the edge of the
lawn is surrounded by several water oaks.

Ecologists and environmental organizations have been urging people to plant more native plants, to build bird-friendly and pollinator-friendly habitat, and to do this by removing at least some of their lawn.

One prime example is Doug Tallamy's HomeGrown National Park where you can register your yard to be part of of this park by replacing at least half of the lawn with native plants.

This is great and I hope that millions of homeowners and other property managers take this step to build native habitat, but there are some important steps to take, especially in urban and suburban areas, to increase the acceptability of these native landscapes. Our yards and our community landscapes, even if they have a good portion of native plants are not wild spaces and will need some regular care. (Actually, I wrote a book on this topic. See below.)

Listening to your landscape

To have a more sustainable landscape, you need to listen...

As a long-time gardener with a masters degree in botany, I was certain that I could garden in north Florida when my husband and I moved here in 2004. I've told this story before, but I was shocked and surprised at how wrong I was. Some Florida gardening truths were quickly discovered like how tulips don't grow well here, not even as annuals, because our winters include warm spells so the soil doesn't stay cold enough. Other revelations have taken more time...

Tropical sage in the herb garden by the kitchen window.

Listen to the birds & bees

Tropical sage (Salvia coccinea) has monopolized much of my herb garden. I transplant some of it from this location when I plant basil, dill, or one of the other annual herbs, but mostly I leave this native volunteer in place because it attracts hummingbirds, butterflies, several types of bees.

I started the herb garden years ago by ripping out the tea roses and various non-native shrubs that were not doing well in this WSW-facing wall. At first everything was in its assigned place, but when the sage arrived, everything changed. I listened to the birds and the bees who needed this beautiful native more than I needed a neat garden.

Remarkable resurrection ferns

Resurrection ferns dried and hydrated.

Resurrection fern (Pleopeltis michauxiana) and tropical resurrection fern (Pleopeltis polypodioides)

While I'd seen spare populations of resurrection ferns when I lived in Maryland, I really became aware of them when I read "Light a Distant Fire," an historic novel about Osceola and the Seminoles by Lucia St. Clair Robson. She wrote about how the scouts could disappear into the ferns on the live oak branches. After we moved to Florida, I came to see how this could be accomplished.

This is a true fern that reproduces via spores, but it is also an epiphyte or air plant. It does not need to be in contact with soil to live. It derives its needs from the air, especially the humidity and dust that it carries.

The common name of resurrection fern is due to its ability to lose 95% of its moisture, stop its photosynthesis, and go into a type of suspended state when it appears to be dead. When it rains or when the humidity becomes high enough, the fronds unfurl and turn green in a matter of hours. Hence the name resurrection fern, because it arises from the dead.
