Coontie: A Jurassic Leftover

Coontie 2Coontie (Zamia floridana) is one of about 200 remaining species of cycads. Cycads are primitive palm-like plants that were a dominant plant species some 200 million years ago. Able to survive harsh conditions, yearly freezes, poor soil and even high salinity it is no wonder that some of these tough species managed to survive to modern day.

Coontie and other cycads are gymnosperms which means they cone-bearing. These species are also dioecious which means they have separate male and female plants. Male plants produce cones full of pollen and female plants produce cones that contain seeds. Cycads are broken down into three families of plants: Zamiaceae, Cycadaceae and Stangeriaceae which include 11 genera with about 200 species. DSCN0361

Coontie is one of the oldest species of plants still found growing today and was resident on Earth in the time of the dinosaurs. Many cycads were likely used as forage for herbivorous dinosaurs. The seeds of Coontie are bright orange and are used as food sources for several species of birds that help to distribute the seeds to new areas. Coontie, like magnolia, is a species so old that it predates bees and is pollinated by beetles.

Coontie in Florida: Florida was once home to vast swaths of Coontie plants and the root of this species became an important food source for inhabitants. First consumed by the Timucua and Calusa tribes, the starchy tuber of Coontie can be carefully processed to produce a type of flour. In the mid-18th century the Seminole tribe moved into the Coontie-rich areas of Florida and also began to use the plant as a food source. The name Coontie is actually a Seminole words that translates to something close to “flour root”. Coontie was later added to the diets of European settlers in Florida, but great care had to be used in the preparation of DSCN0363the plant. Coontie contains a toxin called cycasin in the root that must be removed through repeated washing or boiling before the root can be safe for consumption.

Also known as Florida Arrowroot, Coontie became a very popular and inexpensive starch source in the late 19th and early 20th centuries. A number of Florida factories produced a starch sold as Florida Arrowroot from 1830 to 1925 and production peaked around the time of World War I. During this period Coontie was processed in immense quantities and many Florida plant populations became depleted. Forests were cleared as lumber needs of the factories increased and the natural habitat of Coontie quickly began to dwindle. The slow growing plant was not able to replenish itself to return to its former abundance.

The Extinction and Rebirth of a DSCN0302Butterfly: Habitats for Coontie came increasingly under fire as populations in Florida swelled during the 20th century. Between starch production and increased building, numbers of Florida Coontie continued to decline. The tiny Atala butterfly (Eumaeus atala) followed suit.

The Atala is a small but colorful butterflies that uses the new-growth leaves of Coontie as a larval host-plant. Atala butterflies are able to consume the toxic cycasin resident in Coontie and because of this are distasteful to birds. The bright orange bodies of these butterflies are thought to be an aposematic warning sign. As the host plant became harder for the butterfly to find, populations of the Atala butterfly continued to plummet. Attempts at breeding and release programs were hampered by frequent and devastating hurricanes until the butterfly was thought to be extinct in the United States in 1965.

In 1979 a small colony of Atala butterflies was discovered in Virginia Key. Since then Coontie has regained popularity as a landscaping plant and the tiny original population has begun to spread back into areas formerly inhabited by the Atala. The rebound of this species should continue as the plant is replaced back into the landscape. The story of the Coontie reminds us that life in our environment is connected in a vast web of relationships and that the removal of any thread in that web may have vast and far-reaching consequences for our precious world.

To see some fantastic photos of Atalas in all stages of development check out this link to a selection of photos by a Alata butterfly enthusiast.

DSCN0350Taxonomy: Zamia comes from the Greek word “azaniae” which means pine cone. Coontie was first described as a species by Linnaeus in 1763 and the species has been known by several different scientific names since then. Currently there is argument that all Coontie in Florida are of one species Zamia floridana, but the plant may have regional differences in appearance and size. Other argue that Florida is home to several distinct species of Zamia that each should be recognized as individual species. The debate continues.

The Atala butterfly was first described by Cuban zoologist Felipe Poey. The butterfly is named for the heroine of an 1801 novella, Atala ou les amours de deux sauvages dans le désert, written by François-René de Chateaubriand, the “Father of French Romanticism”.

Peppergrass: Weed or Host Plant?

Some say weed, I say host plant!

Some of the earliest spring butterflies are members of a butterfly family Pieridae and are commonly known known as the Whites and Sulphurs. The Whites: namely the Cabbage White, Checkered White and Great Florida White can often be seen on roadsides and medians throughout Florida, especially in the early spring. These species host on greens in the mustard family like cabbages, mustard greens and collard greens. (Try picking up a few of these greens not for food but for the butterflies. )

Peppergrass (Lepidium virginicum) or Poor Man’s Pepper is a host plant for these delicate beauties that you may already have growing in your yard. Besides feeding butterflies, you can also add the young leaves to salads and the seed pods can be used as a substitute for black pepper. It may not be the most attractive of garden plants, and it may be a brown skeleton by mid-summer but in the Spring peppergrass has some great butterfly uses.

If you have a fenced yard that your neighbors won’t complain about, consider letting a small patch of peppergrass go wild by mowing around it. It is amazing how many butterflies are drawn to common weeds.

Coming soon to a tree grove near you: Hippeastrum

Beneath the canopy of the Franklin Delano Roosevelt Live Oak in the Richard T. Bowers Historic Tree Grove, a riot of color is preparing itself to emerge. A lush bed

of Hippeastrum has started putting up flower spikes and soon will be a showy wash of huge orange flowers. Once they start blooming we’ll have a consistent  patch of bright color that will last about a month until the last blooms finish.

The rest of the year these plants will leave behind gorgeous green foliage but I am always struck by their beauty each spring. Totally unexpected, they throw their stalks of flowers into the air in mid-February and are blooming like champs by the first day of March.DSCN7300 They may not be butterfly flowers, but they are certainly gardener-friendly.

More on Hippeastrum: Hippeastrum, from the Greek for "horseman's star" and now also known as knight's star are popularly, but erroneously, known as Amaryllis. Amaryllis is in fact a monotypic genus (only one species) from Africa that look similar to hippeastrums but have no leaves.

Hippeastrum is a commonly sold bulbous plant that readily grows in pots and indoors. There are around 70-75 species of hippeastrums available on the market, but somehow I favor these brilliant orange ones. Certainly they are not the most showy cultivar but their color is eye-catching and remarkable.

Plantain

One of the few plants that is looking fantastic in the gardens right now is plantain, also known by the common name of ribgrass. While almost everything else is brown or just barely coming back to life, the plantain makes a few patches of lush green in the Historic Tree Grove and butterfly

gardens.

Plantain (Plantago lanceolata) is one of about 200 species of inconspicuous grass like plants common to disturbed areas like roadsides and yards. Often the wide blades of this plant can be spotted in a lawn before the rest of the grasses come to life after a long winter. Plantain is the host to the lovely Buckeye Butterfly (Junonia coenia) which is common to the Tampa Bay region of Florida. The caterpillars are charcoal grey to black and covered in tiny non-stinging spines.

Since prehistoric times plantagos have been used in poultices to cure rashes from insect bites and poison ivy and also as a tincture to help heal coughs and bronchitis. Of no relation to the similarly named banana cousin, broad leaf plantain varieties have sometimes been used as a leaf vegetable in salads.

Signs of Life

Little signs of life are beginning to show in the gardens as plants begin tentatively putting out new leaves and growth. Hopefully this most recent cold snap does not serve to dissuade the gardens from putting on the green and getting their foliage ready for spring.

The Walter’s Viburnum (Viburnum obovatum) has gotten us rolling with small patches of white flowers dotting the foliage. Passionvines (Passiflora sp.), Sensitive Plant (Mimosa strigillosa), and Canna Lilies (Canna sp.) are perking up with fresh shoots of foliage. The Rosinweed (Silphium) has already put on a singular bloom and here and there Stinkhorn Mushrooms (Clathrus columnatus) are peeking up their weird and stinky tops.

The butterflies in the Flight Encounter are mostly in a holding pattern waiting for some warmer weather. As they stay very still in cold weather this offers a great opportunity for extreme close-up photos.

So, how is your garden growing?

Dianthus

The genus dianthus contains about 300 species of flowering plants including some well known flowers like carnations

(D. caryophyllus), pinks (D. plumarius and related species) and sweet william (D. barbatus). Most of these flowers are native to Europe and Asia with a few species from North America and North Africa.

Dianthus is a cold hardy annual that can take a light frost with hardly a notice. These 'Strawberry Parfait' Dianthus (Dianthus chinensis) have been mixed in with pink and red petunias and purple Dianthus for a lovely carpet of color along the front walk to BioWorks. They will grow 6 to 8 inches in height and bloom beautifully. Some butterflies, including the Gulf Fritillary will nectar on dianthus, especially when nothing else can be found for food.

What’s in a name? The name dianthus comes from the Greek words dios which means “god” and anthos “flower”. This name was given by the Greek botanist Theophrastus who is known by some as the “Father of Botany”. Theophrastes ten volume Enquiry into Plants and eight volume On the Causes of Plants remain as the first systemization of the botanical world where plants were classified and grouped based upon their modes of generation, their localities, their sizes, and according to their practical uses.

in Just- spring

Delicate pinkish-purple blossoms quivering against smooth bark are the first harbingers of an early Spring in our gardens. Eastern Redbud (Cercis canadensis) are deciduous trees that put forth a showy bloom of bright flowers before they even begin to put on leaves. Several of the trees lining our main drive are already blooming a happy riot of color.

Something about this time time of year always makes my gardener’s heart a little hopeful of the things to come and sends me scurrying for a volume of e.e. cummings. One of my favorite poets, cummings often wrote poetry besprinkled with the language of gardens and it is obvious that the poet had a soft spot for flowers and for Spring. DSCN7267

this is the garden:colours come and go,

    this is the garden:colours come and go,
    frail azures fluttering from night's outer wing
    strong silent greens silently lingering,
    absolute lights like baths of golden snow.
    This is the garden:pursed lips do blow
    upon cool flutes within wide glooms,and sing
    (of harps celestial to the quivering string)
    invisible faces hauntingly and slow.

    This is the garden. Time shall surely reap
    and on Death's blade lie many a flower DSCN4990curled,
    in other lands where other songs be sung;
    yet stand They here enraptured,as among
    the slow deep trees perpetual of sleep
    some silver-fingered fountain steals the world.
    e.e. cummings
