Mother Nature's Artistry

This edition of Mother Nature's Artistry (published the last day of every month) is a shot of the leaves of Cycas revoluta (King Sago) while they are still soft and unfurling.

Once the leaflets have flattened out, they become very rigid and prickly--a huge change from the soft texture seen in this photo!

Thinning peaches

Peach trees typically set too much fruit.  Unless you thin it out, you will have lots of small fruit and not many of the nice big eating peaches.  Thinning should take place when fruit development has reached marble size up to the size of a quarter.  By then you can get a good idea of how much fruit has set and is holding on the tree. 
Thinning is performed by simply twisting or rubbing off the small fruits.  Thin the developing fruits so that you only have one fruit per 5 to 6 inches of branch.  I like the fruit I leave to be on the underside of the branch.  This makes them less visible to passing birds that might like to take a bite! 
By thinning, more of the tree's energy is available to go into fewer fruit.  The result is fewer but larger fruit--better for eating!
In the above photo you can see there are way too many fruit developing on the branches.
Below is the same branch after thinning.  The tree will put more energy into fewer fruit, resulting in big delicious peaches!

Chickasaw plum (Prunus angustifolia)

Chickasaw plum is a native of the Southeastern U.S. and they're in bloom right now in Central Florida.  Like most plums they are deciduous, and when they bloom in spring the branches are completely covered with white blossoms. 














The flowers are followed by small 1/2 to 3/4 inch diameter yellow to reddish plums that are eaten by humans and wildlife alike.  Fruits can be eaten fresh, made into jelly, or dried.


Prunus angustifolia has a tendency to sucker readily so it's not often used in formal landscaping but it's an ideal small tree for naturalized areas, background plantings, or mixed borders.  The trees grow to about 20 foot tall in USDA Zones 5 through 9. If allowed to sucker freely, it develops more of a shrubby habit.  They are very drought-tolerant once established.


The flowers are a good food source for honeybees.  Supposedly butterflies are also attracted to the blooms but in my yard they bloom before the butterfly populations have started increasing in the spring.

Billbergia Windii

This is one of my favorite little bromeliads:  Billbergia 'Windii'.  The plants only grow about a foot tall but the pendulous flower spike can reach nearly two feet in length!  They are great for hanging baskets or planted along a low wall where the blooms can spill over.  They multiply rapidly and individual plants will bloom at various times throughout the year.  These came through freezing temps in the mid to upper 20s F with no damage this winter so they are moving higher on my list of favorites.  They grow well in shade or filtered sun and require no additional care.  Rainfall generally provides sufficient moisture.



Here is the flower spike as it's emerging from the foliage and starting to arch over.
The above grouping is in bloom right now.  These are planted on sloping ground above the fish pond so the flowers can hang down and show themselves nicely.

The pink bracts open out to reveal the blue and green flowers inside.  What a beauty!



Here are my other posts on bromeliads

Snag some wildlife!

A snag tree is a standing dead or nearly dead tree.  Snags are extremely valuable habitat for birds, mammals, reptiles, and amphibians.  Insects under the bark of snags provide food for woodpeckers, birds, squirrels, and other mammals.  Many birds and mammals will also use hollowed-out snags as living or nesting areas.  To really attract a wide variety of life to your property make sure to leave some dead or dying trees.  If you have no dead trees, you can create the same effect by burying large dead trunks or tree limbs in an upright position throughout your landscape.  It won't take long until the wildlife is checking it out!
The center trunk of this tree is hollow inside and no doubt harbors insects that many birds enjoy!
                                                                                   

                                                                                                                 Snags don't have to be large or take up a lot of space.  This is the trunk of a dead citrus tree.






Look closely at all the holes and you can see how many woodpeckers have been enjoying this dead Roseapple trunk!













Even a log on the ground will attract ants, beetles and other insects that lizards and other small animals will use as a food source.










Here a larger animal (maybe gopher tortoise?) has made a burrow under the trunk of a fallen live oak.









Leaving a little dead wood in your yard not only saves you the labor of removing it, but it will increase your enjoyment by attracting a variety of wildlife!

Spiderwort (Tradescantia ohiensis)

Tradescantia ohiensis is a common wildflower that appears in many gardens.  Bright blue flowers with three petals open in the morning and wither away after a few hours. Less common colors are white, pink, and violet. Individual flowers are about an inch across. They bloom most of the year in the warmer parts of its range.  They are drought-tolerant and will grow in full sun to light shade. Leaves are long and narrow (up to 15 inches long). They have a clumping growth habit up to two foot tall.
There are several species throughout the U.S. and they readily hybridize so if you live in an area with more than one species there may be some intermediate varieties.  The flower stems of this particular species are smooth and hairless.  Tradescantia ohiensis may be found throughout the eastern half of the U.S. --USDA Zones 5-10 (or as far north as Zone 3, depending on which website you believe).
Of particular interest are the numerous, fuzzy, blue hairs on the stamens.  These mutate at a cellular level and turn pink when exposed to low levels of nuclear radiation!
(Click to enlarge)
Spiderwort is rarely bothered by insects but may be fed on by Whitetail deer, Cottontail rabbits, and box turtles. 
The Cherokee peoples used Spiderwort in a tea for digestive problems and would rub the crushed leaves on insect bites or stings.  The leaves and stems are edible fresh or cooked.  The flower petals can be candied or added to salads for interesting color.
This is a great low-maintenance perennial flower with a long bloom season, that can warn you of radiation exposure, and it's edible too!

Creature Feature - Cuban Treefrog

Here's the latest installment of Creature Feature (repeats on the first Friday of each month). Today we have a frog nestled inside the leaf of a Costus ginger.
I know he's cute, but this is one of the invasive Cuban treefrogs.  We Floridians are supposed to kill them because they are voracious carnivores and will eat large quantities of our native frogs, toads, lizards, and even small snakes.  Females can grow up to 6 inches in body length and can lay over 15,000 eggs in a single season.  
Cuban treefrog skin secretes a sticky substance that is irritating to the mucous membranes of the human eyes, nose, and mouth.  The burning and itching sensation can last for hours.
They also inhabit bird houses (keeping the birds away), clog plumbing pipes, and cause power outages when they try to seek shelter in electrical equipment!
Over the past few decades they have spread through most of the state of Florida and a few have been seen in South Georgia.

For more on Cuban tree frogs, the damage they do, how to identify them, and how to humanely kill them, see the following publications from:

Arrowroot (Maranta arundinaceae)


Arrowroot (Maranta arundinaceae) is a tropical plant that produces an edible starchy tuber widely used by indigenous peoples for medicine and cooking.  The plant is native to South America, and to the West Indies where the native Arawaks used the plant as a dietary staple and also used the powder to draw out toxins from people wounded by poison arrows.  Native Americans in both North and South America apply Arrowroot as a poultice for snakebite, insect stings or bites, and skin sores.  There is evidence this plant has been cultivated for at least 7,000 years.
The plant is an herbaceous perennial that dies to the ground each winter when the tubers can be dug.  The plants grow about 4 foot tall in full sun to light shade, and bear small white flowers in the summer.
The cylindrical underground roots grow 6-8 inches long, on average, and are sharply pointed at the end (hence the name arrowroot).

At the end of the growing season there will be a cluster of these tubers under each plant.  Each individual tuber will grow a new plant for the following year so they can multiply rapidly if you dig and replant the parts that you don't consume. In areas where the ground doesn't freeze, just leave a few tubers in the ground after harvest. In colder climates, store the tubers in a cool dry location and replant them in the spring.

Watch my video on digging arrowroot here  

The tubers can be eaten boiled, roasted, baked, or fried.  In some cultures they are ground and made into pastries.  Arrowroot flour can be used for gluten-free baking.
The extraction of the starch is a somewhat laborious process:  The tubers are washed, pounded to a pulp, rinsed in clean water, fibrous parts are removed, and the starchy water is allowed to settle.  The  clear water is drained off, fresh water is again added, mixed, and drained.  The remaining starch is then spread to dry in the sun.  The starch yield is about 1/5 of the original weight of the tubers.

The starch can be used as a thickener for sauces, gravies, puddings, jellies, and pie fillings, or as a clear glaze for fruit pies.  As a thickener, it is two to three times as effective as cornstarch.  In Suriname, the Amerindians use the starch as a baby powder, giving the skin a soft, silky, smooth feel.
Old herbals suggest the easily digested starch was often used to soothe bowel irritations by dissolving in hot water or hot milk where it forms a gelatinous solution that cools to a jelly-like mass.  A tablespoon of starch to a pint of liquid forms a sufficient consistency.  It should first be formed into a smooth paste with a little cold water and then the hot liquid should be added while stirring briskly.  A little lemon juice, or herbs and spices may be added for flavor.

The photo above is the edible tubers I harvested from a single random plant.  Each piece will grow a new plant.
