September Flower of the Month

White Snakeroot (Ageratina altissima)

This native plant, commonly known as White Snakeroot, for the mistaken belief that the roots were a treatment for snakebites, is found on the edges of or in open wooded areas and blooms from late summer into late fall. All parts of this plant are poisonous.

Septober's Flowers

SEPTOBER'S FLOWERS

       Due to a lengthy illness in September there was no September flower of the Month. Since most plants blooming in late summer bloom into fall, such as the Sunflowers, September will be combined with October and the new month will be known as Septober.
       The month of September has brought cooler temperatures to the state and little rainfall to central Oklahoma. Fall is here and the leaves are falling. However the month of September brings with it the towering, brightly colored Sunflowers which are continuing from August as well as beautiful Asters and other late summer and fall blooming plants.
       The dry/cool weather has continued into October and so have many of the Septembers flowering plants some of which which will be featured in the Octseper's flowers of the month.

August Flowers

AUGUST'S FLOWERS

July has flown by and we are two weeks into August. It has been an erratic month weather wise in Oklahoma with temperatures as high as 107 and as low (high) in the 70's and rainfall going from drought conditions to flooding rains. The cooler temperatures have “greened” things up and hopefully some plant species will begin to bloom.
School has started in many places and vacations have been taken however nature does not stop for vacations. Plants keep growing, reproducing and blooming including the Tall Thistle, Spurges, and Sunflowers among many others. Remember summer isn't over. Enjoy

July's Flowers

JULY'S FLOWERS

Summer officially arrived June 20th and it's July. The weather is heating up and drying out which is typical for Oklahoma in July and August. Some plant species have peaked, as far as blooming, such as the Indian Blanket, Spiderworts and Blackeyed Susan. The majestic sunflowers will soon appear as well as other heat tolerant species in the Asteraceae (Aster) family. It looks like a productive summer for the native flowering plants. The bees , butterflies and other insects, which rely on these flowers, should also have a good summer.

Have a happy and safe 4th of July

June Flowers

JUNE FLOWERS

June flowers are here. We have had beneficial rain in May so June looks pretty good. Over all, so far, at least in the local area, the plant population is doing well but not as well as I'd hoped. Looking back in my photo archives there were several years which were spectacular, as far as numbers of plant species blooming. This does not appear to be one of those years.
Many of the June flowering plants are a continuation of May and many will continue through the summer. Among them are some of the largest, showiest and most common blooming plants including the Penstemons, Butterfly Weed, Coneflowers, Evening Primroses, Yucca, Winecups, Spiderworts and some Thistle species, to name a few. Of course there are the smaller, although not as numerous or visible, itsy bitsy flowers (smaller than one half inch) which are interesting, intricate and just as beautiful as their larger cousins. A few of these are the Milkworts, Pennyroyals, and Pinks. By mid July the rains should diminish and the heat tolerant species will appear and some species disappear.

May Flowers

MAY FLOWERS

April showers brought more beneficial moisture (and unfortunately tornadoes) to this part of the world. But an abundance of moisture means the wild plant population is thriving. Many new species are appearing and continuing from April and many will continue through the summer. Some species such as the beautiful but parasitic Indian Paintbrush will appear and disappear in a relatively short time, to be replaced by more heat tolerant species. Here are a few May blooming plants.

Spring Preview

Preview of coming flowers. Shepard's Purse, Henbit, False Garlic, Spring Beauty, Field Pansy, and the Common Dandelion.
These (left) are a few common flowers that appear in lawns and gardens in early spring. Some are considered a nuisance since they may take over a lawn.
Many chemicals are used to eradicate these nuisance plants from urban lawns which, for the most part, will naturally disappear with the arrival of hot weather.
Remember all of the chemical used on lawns will eventually end up in the local water supply and in your drinking water.
