The American lotus (Nelumbo lutea) is an unusual plant, as it can survive floating in fresh water! It is a plant native to the hot and cold climates of the United States and Canada, including Florida, as shown by the blue shading in Figure 2. The American lotus is found near the floodplains and tributaries of rivers, as well as muddy lake margins, marshes, and swamps. If you would like to see this lovely lotus, Lake Okeechobee and the Glades County would be excellent places to visit.


The American lotus grows mainly in the summer and can extend up to 3 feet in water! Because it can be relatively large, the plant requires ample depth to grow and space for its leaves to float along the surface of the water. The showy flowers are yellow/white in color and are typically 6 inches in diameter (Figure 1).

Many people confuse the American lotus (genus Nelumbo) with the water lily (genus Nymphaea), but an easy way to distinguish between them is to analyze their leaves (Figure 3). The water lily has indentations or cuts on its leaves, but the American lotus has leaves that are flat and circular (Figure 3).

In the past, humans have eaten parts of the American lotus for food: the roots baked like a potato, the seeds toasted like nuts, and the leaves cooked like lettuce leaves. They can be used for decoration along with other flowers. These fragrant water flowers are gifts to the waters of Florida, and can be a beautiful addition to your backyard pond.

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...
