Lignum vitae: the Wood of Life

The lgnum vitae (Gualacum sanctum). This must be a special tree with two Latin names. Actually, this IS a special tree for many reasons. It grows slowly--about an inch per year. The wood is so dense that it sinks in water. Its wood was highly prized for propellers and judges' gavels. Because it's resinous, the wood was also good for ball bearings and hinges--they are self lubricating. The resin has medicinal properties: it reduces inflammation, suppresses coughs, and was used to treat syphilis. Because of all its uses, it was widely harvested and because of its extremely slow growth, the tree is rare in most of the Florida Keys, its native habitat.

Here's more information and photos of the tree on Floridata.com. It has amazingly blue flowers.

But on Lignumvitae Key most of the population was spared from the harvest because it was privately held and accessible only by boat. This key is now a state park. It's open on Thursday through Sunday and tours of the house and trails are only on Friday through Sunday.  It's on the bay side of Islamorada at mile marker 78.5.  Here's the park's website. It's worth the trip, but bring your insect repellent.

Since 1973, it's been a registered
natural landmark.

This 20' tall lignum vitae tree in the garden withstood hurricane Wilma's flooding where the bottom portion of the garden was under saltwater for several days. They estimate that it's more than 80 years old. Let's see, if you do the math, 20 x 12 = 240 inches tall. Gosh, this tree is probably a lot older than 80; if you consider that it's growing in a civil war fort, it's probably 150 years old.

 The KW Garden Club displays this piece of wood.

This chunk of lignum vitae wood is about a foot tall and 10" x 6" across. It weighs 82 pounds!

Lignum vitae, just one of many wonders in Florida.

Quick quiz: What other state park is also named after a native plant?

Yes, it's Torreya State Park. We wrote about a field trip there last year: http://fnpsblog.blogspot.com/2010/12/field-trip-to-torreya-state-park-with.html

Florida Native Azaleas

Image
Piedmont Azalea, Rhododendron canescens. Photo by Lilly Anderson-Messec By Lilly Anderson-Messec While growing up in North Florida, I began to recognize the arrival of spring by the boisterous show of white, pink, and fuchsia blooms of azalea shrubs. The house I grew up in had large, mature azalea hedges with a variety of different colors and forms. Every spring, my mom would bring in vases full of them and my dad loved to point out the showy shrubs as we drove through town. I suppose I assumed these plants were native, but most likely I never gave it a thought. I didn’t differentiate a native plant from a non-native one because I didn’t yet know the importance of native plants as the basis of our functioning ecosystems. I was so surprised when I learned the azaleas I was so familiar with (Rhododendron indicum) are actually transplants from Asia! They are favored by the horticultural industry for their fast, vigorous, and dense growth of evergreen leaves and large, showy blooms. Curio...

Wednesday's Wildflower:Spanish Needle

Image
Spanish Needle, Bidens Alba Submitted by Donna Bollenbach, Suncoast Chapter Biden's alba , all photos by Donna Bollenbach Nothing attracts more butterflies and bees than a simple white flower called Bidens alba . Also called Romerillo, Beggar’s Tick, Spanish Needle or Monkey’s Lice, this Florida native wildflower is the third most reliable source of nectar for pollinators in our state. There would be many starving bees and butterflies if not for the Bidens family of flowers. More so, Bidens alba and its sister plant, Bidens pilosa , are both edible and have medicinal value. Yet, many gardeners have a love/hate relationship the plant, and some even consider it a pesky weed. Why?

Paradise Tree: Beautiful and Useful

Image
"The native Paradise tree is more useful than Google, and easy to grow." And how could any blogger resist leading off with this intriguing quote from the Key West Garden Club? I am a Master Gardener and a Master Naturalist, but I only know so much; so I always check out  statistics from experts before posting information about plants. I have a beautiful Paradise tree in my yard, it came from the raffle table at my chapter's program night about six years ago.   Paradise tree                Simarouba glauca For the first six years the little tree had a perfect, closed, cone shape; but just this summer I was astounded one morning to walk out and notice that my tree had changed. The canopy had begun to open up, there were open spaces between the layers of branches. It seemed to happen overnight. Proving again that a garden is constantly in motion, which is one of the fascinating things about o...
