Dill is a beautiful, easy-to-grow herb in Florida

Pollinators love dill flowers.

Dill (Anethum graveolens) is a fast-growing, cool-weather annual with a long taproot. It provides both a classic herb and a spice--the leaves are called dill weed, and used fresh or dried as a herb in salads or as a garnish, while the seeds are used as a spice for pickling or in potato and pasta salads. Dill is native to the Mediterranean region, but it's grown world wide.

The majestic dill flower heads can reach fourteen inches across. They attract a wide variety of pollinators, and importantly for organic gardeners, dill attracts the small parasitoid wasps that prey on tomato worms and other garden pests. 

All the above-ground parts of the dill plant are edible. The leaves and the seeds are most often harvested, but you can also eat the flowers and the stems. 

Taxonomic note: The Kew Garden's Plants of the World Online database considers dill (Anethum graveolens) and several other related species to be synonyms of false fennel (Ridolfia segetum). I have not found other organizations joining in on this lumping of species as yet, but there may be a dill name change in the future.

Hibiscus: Plants with the most beautiful flowers

A scarlet rosemallow (Hibiscus coccineus):
 a Florida native

There are 432 Hibiscus species that are found worldwide, and with their beautiful flowers, many are grown in gardens and some are even used as crops. In general, the flowers are large and showy.

For example, see the scarlet rosemallow in the lead photo. Here there are five green sepals subtending five large red petals. The pistil, the female reproductive part of a plant, is attached to the center of the flower. The pistil is made up of a five-chambered ovary where seeds develop, the style that is a long tube between the ovary and five round stigmas where the pollen is absorbed. A stamen, the male reproductive structure, consists of the anther that holds the pollen, and a stalk called the filament. In hibiscus flowers, the filaments fuse into a tube that surrounds the style. Numerous anthers stick out from the filaments below the five stigmas at the top of the style. The prominent pistil with all those anthers is one reason the hibiscus flowers are so showy.

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.

Green-eyes: beautiful and resilient Florida wildflowers

Florida greeneyes bloom nearly year-round and attract
many types of pollinators. Notice how showy the
disk florets are with their extra-long stamens
and their folded-down top edges. 

The greeneyes (Berlandiera spp.) are in the daisy family (Asteraceae) and have the typical flower head arrangement of this family with fertile central disk florets that produce the seeds surrounded by sterile showy ray florets that look and act like petals. They are perennials with a long tap root.

In the case of greeneyes, the flower heads consist of about eight bright yellow ray florets, each with a notched tip, surrounding a head of greenish-yellow tubular disk florets, which is, of course,  why they are called greeneyes. When disk florets open, they reveal maroon anthers and a long yellow stigma, and they smell like chocolate. 

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.)

Organic Methods for Vegetable Gardening in Florida: 2nd Edition

Order directly from our publisher:
University Press of Florida 

Melissa and I worked with University Press of Florida to improve, update, and reorganize our book. The photos, including many new ones, are now located throughout the book, not just in the center, which will make it much easier to read. We've explained our process in the new preface included here for your information.

Preface to the Second Edition 

Much has happened in plant science and organic gardening techniques in the almost 10 years since we began researching and writing the first edition of this book, so we agreed to spend some time to revisit and update the content for this edition. We were eager to work on this project so that Florida’s vegetable gardeners would have easy access to this new information. 

Red cedar: an important habitat tree

A female red cedar with fruit.

Red cedar (Juniperus virginiana) is medium-sized, dioecious evergreen conifer with female trees that bear waxy, berry-like cones, which many types of birds will eat as the weather grows colder.

While most botanists agree that there is one species of red cedar that's native to most of eastern North America, the old precedent recognized coastal red cedar (J. silicicola) and eastern red cedar (J. virginiana) a bit inland, with a big range from Texas to southern Ontario. This old protocol meant that except for the northern border of Florida's Panhandle, the red cedars native to Florida were the coastal species.

Red cedar is in the cypress family (Cupressaceae), which has world-wide distribution--except for Antarctica. Other members of this family found in Florida are two cypresses: pond cypress (Taxodium ascendens) and bald cypress (T. distichum); Atlantic white cedar (Chamaecyparis thyoides); plus the non-natives: oriental arborvitae (Platycladus orientalis) and white cypress-pine (Callitris glaucophylla).

Fall cucumbers

Cucumber (Cucumis sativus) is in the squash family (Cucurbitaceae) and is more closely related to melons than the squashes, which are in the Cucurbita genus. It's native to India but has been under cultivation as a crop for about 3,000 years. Now, it is widely cultivated around the world.

Male and female cucumber flowers. The female flower sits atop a small, preformed fruit. If the flower is not adequately pollinated, then the fruit will not expand, turn yellow, and fall off the vine.

Marigolds

Beautiful marigolds!

Inchworm by Danny Kaye

Inchworm, inchworm (two and two are four)
Measuring the marigolds (four and four are eight)
You and your arithmetic (eight and eight are sixteen)
You'll probably go far (sixteen and sixteen are thirty-two)

Inchworm, inchworm (two and two are four)
Measuring the marigolds (four and four are eight)
Seems to me, you'd stop and see (eight and eight are sixteen)
How beautiful they are (sixteen and sixteen are thirty-two)

Marigolds have been under cultivation for centuries

Habitat gardening

In natural areas, the soil ecosystem supports the plants,
which support the insects, which in turn support
the birds and other wildlife.

Florida's default landscapes

Most yards in Florida consist of highly maintained monoculture lawns, a few stand-alone trees, and a fringe of foundation plants around the buildings. This is the opposite of habitat gardening because typical Florida lawn care includes regular landscape-wide applications of insecticides, herbicides, fungicides and other poisons. Then since these pesticides are not good for the turfgrass, synthetic fertilizer is applied to keep it green.

This treatment damages the soil ecosystem (shown in the poster here), which plays an important role in keeping the plants healthy, which then support the insects and the birds. In addition, much of the lawn chemicals have rinsed through the soil or have been carried away with erosion to pollute our waterways causing too much algae growth and toxic dead zones.
