I first observed Scleria lithosperma a few months ago, on May 31, 2012, in Key Largo, Florida. This is the only Scleria species listed as Endangered in Florida. Including S. lithosperma, I’ve now observed nine of the ten Scleria species known from Florida.  Scleria is a genus belonging to the monocotyledonous family Cyperaceae.  All Scleria species of Florida are native here, except for Scleria lacustris.

The fruit of all Scleria species is an achene (as is true for all other species of Cyperaceae).  An achene is a dry, indehiscent, one-seeded, fruit.   Species of Scleria, like species of other cyperaceous genera, are distinguished from one another largely according to features of their achenes.  All ten of our Scleria species have white achenes (an atypical feature among Florida Cyperaceae, overall) and their achenes are minute - ranging, collectively, from one to four mm long.   Because the achenes are so small, the beginner requires a microscope to see them clearly and to identify Scleria plants to species.

Florida species of Scleria appear, superficially, grass-like and weedy, and the average person would consider them unremarkable.  Yet, their achenes appear unique and beautiful under the microscope. I’ll now review selected features of the achenes.  While doing so, I’ll refer to the handout which I’ve distributed today. ¹ 

Heather DuPlooy, the Garden's Education coordinator, reports to us about what's been happening during summer camp. Here's what she had to say recently.

Walking around the classroom at the Naples Botanical Garden Summer Camp, I am distracted by delicate, colorful art pieces that look like stained glass. Camp counselor, Shannon Guidry, who is showing me around before my presentation to the campers, tells me that the work is inspired by the amazing hand blown glass art of Dale Chihuly.

 The vibrant artwork is part of an activity presented by Jessica Wozniak from the Naples Museum of Art. While I admire their work, the students are carefully weaving multicolored strands of yarn through garden pots which will later be planted with seeds from the garden. This gives Shannon a couple minutes to talk to me about what the kids have been up to this week. A lot!

At Naples Botanical Garden, the butterfly count has been high this spring for most of the Florida butterflies. Most people (myself included) were affected by Hurricane Wilma about five years ago and lost a lot of their garden’s canopy. Now finally, we are seeing a big return of the zebra long wings (Florida’s state butterfly) and also the Julia, which are two of our Florida heliconian butterflies, since the tree canopies are beginning to return.

These two butterflies like to play in shade or dappled sun, like under the canopy trees provide. I have always suggested when planting Passion vines, their host plant, i.e. plants that female butterflies deposit their eggs on, that they should be planted in shade or partial shade for maximum efficiency.

I wrapped up my second “photo shoot” for the Garden yesterday for the last of our Summer Picnic concerts. It was another lovely Florida morning, partly cloudy skies and a mild breeze blowing. In fact, Southwest Fla. temps have been cooler than St. Louis and parts farther north!

Walking amidst the families and observing couples young and old sharing a midday repast on the day of our nation’s independence uplifted me. To be sure, the Garden exudes a special magic, but the tropical music and strong vocals combined with a lazy day vibe made me feel as though time does stand still despite our hyper-connected world. (I do appreciate the irony as I posted on Facebook prior to, during and after the concert!) But here’s the thing…people want to connect.

A hundred and forty years ago or so, I learned to drive a faded maroon 1950 Ford stick shift at Dawes Arboretum just outside Newark, Ohio. My brother, who must have been heavily medicated, took on this thankless task of teaching me how to drive; and I did manage soon after to get a driver’s license.

Here I am again at Dawes, June 2012, only this time, in addition to roadways, there are majestic tents nestled among majestic trees. There is an enormous climbing tree outfitted with swings, straps and pulleys and some wild and crazy people who you aspire to be (but lack the nerve to be), ascending to the highest branches.

There are five food stations to tempt the most determined ‘weight watcher’. There are delicate wildflowers, regular flowers, pots of flowers, lovely scrims hanging from high branches, fireflies, a setting sun through lacey branches and lots of friendly folk, including a most charming Ex.ecutive Director, Luke Messinger.
