Wildflower Wednesday Part 2: A Thanksgiving Week Long Celebration

River Oats was the first native grass I added to the garden and I have never regretted it.

much earlier in the fall

It's a  clump-forming, upright, ornamental grass with wide bright green leaves and gracefully arching and nodding clusters of oat like flowers (spikelets) that emerge green then turn brown with age. Leaves and flower heads turn a rich tan in autumn and reddish-bronze by winter.  I think it's beautiful all year long, but I like to give it a good haircut by early February when the seed heads have fallen off.  Just cut it back to the basal rosette and new leaves will emerge when it warms up.

 even the softest of breezes will make the seed heads flutter

Good looking plants that also provide for garden critters are a must for my garden and River Oats has decent wildlife value.   Because it's wind pollinated there won't be any pollinators buzzing around the pretty spikelet flowers, but, I am happy to report that it's a host plant for several roadside skippers and a few butterflies.  That makes me happy!

River Oats gives my garden much needed contrast and texture almost all year.  It's a perfect companion for upright  Panicum virgatum 'Northwind',  the blue-grey needles of  Juniperus virginiana 'Grey Owl', native ex-asters and the purple Waiting Bench.

naturalized under oaks and hickory trees  with Hypericum frondosum, Penstemon calycosus and other native plants.

I use it as an accent plant in a raised bed near the front entrance, but, love that it has naturalized in my garden and mimics almost perfectly the oak-hickory woodlands found adjacent to a cedar glade. That was my goal when I planted the center garden a few years ago. It's still a golden brown and the hypericum is just about hyper colored!  It's especially nice to see on  a rainy day when the colors are intensified.

Chasmanthium latifolium will grow anywhere (Eastern USA, Zone 3 to 8); glades, stream banks, dry forests, shade and clay soil.  Please note I said, anywhere! Which brings us back to my "I have never regretted" planting it statement. When happy, it is a rampant self seeder and requires vigilance to catch the seedlings. Think beautiful ground cover with several seasons of interest. Think about this before you decide to plant it in your garden. Think about what you want from it...If you want a plant that will naturalize and create a large swath then this is the grass for you! If you don't mind keeping it in check, pulling out unwanted seedlings, then this is the  grass for you.  If you want a gorgeous grass with  almost year round beauty, then this is the grass for you.

 Personally, I never share this plant without first letting gardeners know that it is a marvelous ground cover and they'll have lots of dried seed heads for flower arranging.

Bright green leaves turn a coppery color after frost and eventually brown by winter

If you've decided you want to invite River Oats into your garden. Then do yourself a favor and let the seed heads and golden bamboo like leaves stand all winter long. You'll love the winter interest and the seed heads will dance in the breeze.

  I can't wait to see them standing tall and golden in the snow.

Welcome to Clay and Limestone and  Part 2 of  the Thanksgiving week long celebration of wildflowers. All across America families and friends are making plans to gather for Thanksgiving dinner. It's our annual celebration of the "First Thanksgiving" when colonists celebrated arriving safely in the New World.

In my house, before the feasting begins, we all take turns sharing our feelings of gratitude. This year, I am especially grateful for the health and well being of my family; for loving and supportive friends; for rain that finally fell in Middle Tennessee; and, for wildflowers that bloomed no matter how horrid the weather has been. Please join me any time this week to share and celebrate the wonderful wildflowers that live and thrive in your gardens. Remember, it doesn't matter if they are in bloom or not. Please leave a comment and add your name to Mr Linky so others can pop over to see your Wildflower Wednesday post.

Sun Salutation at Couchville Cedar Glade

Couchville Cedar Glade is special. If you get a chance to visit a glade...go. There is nothing quite like its stark beauty.

Here's what Thomas Hemmerly, author of my favorite book, Wildflowers of the Central South has to say:

"The cedar glade micro-environment is a harsh, imposing one. Summers are hot and dry, and the thin, exposed soil dries out soon after rains. Winters are cold and wet; rains are more frequent, and evaporation rates much slower. Plants and other organisms must have life cycles synchronized with these changing conditions. Once occupying approximately 5 percent of the Central Basin, cedar glades have been considerably reduced in extent by man's activities. As a result, some of the plants indigenous to the glades are in peril."

Now onto the the trail....




April 2008

June 2008...It's greener and the shrubs are fuller... all the late winter/early spring annuals have bloomed and gone to seed. It's getting dryer in the glade. July and August will bring serious heat and drought.

But, I was heading to the glade to see Tennessee Coneflower in bloom. Tennessee Coneflower/Echinacea tennesseensis is endemic to cedar glades. It's found naturally growing and thriving in only five places all within 14 miles of Nashville. I have been looking forward to this since last summer!

I knew what to expect, but I wasn't prepared for the magnitude...



of this...


Fields of Tennessee Coneflower. Did I say fields? This is a colony of coneflowers. This is what Couchville Cedar Glade is about...it's the largest colony of coneflowers growing in its native habitat. Now that the Coneflower is federally protected, we will get to see these fields of flowers for a very long time.

But that's not all! Look closely! (click to enlarge). Just look and see if you notice what I noticed? Do you see it?

Each and every one of the coneflowers is facing in the same direction...eastward, toward the sun.

A perfect Sun Salutation that will be continued all day long...They will keep their lovely faces turned toward the sun as it moves through the sky!


Other flowers are known to follow the sun, the sunflower, for instance, but it's rare that we get to see fields of them staring adoringly at the sun. Nor are they an endangered species and grow under such harsh conditions.


In case you haven't seen enough

Aren't they lovely?
This isn't one big field. It's several fields all connected by small woodlands of Juniperus virginiana, Hypericum and Aromatic Sumac. The soils are deeper there, maybe 8 to 12 inches. The soils in the fields are much shallower...2 to 8 inches.

Coneflower can't be stopped by shallow soil..it has a tap root that reaches down to find cracks in the underlying limestone bedrock. In fact, too rich a soil makes the coneflower stems weak.

There is more to the glade then coneflowers!

There is this odd spongy growth.

and decaying matter is home to mushroom and other fungi.

There is the every present and incredibly beautiful...limestone.

Wildflowers like Butterfly Weed and Ratibida (pinnate prairie coneflower).


We also saw deer....a first!



and more coneflower.

You can see that the coneflower is growing in extremely rocky and shallow soil. Seeds are dispersed and fall to the ground. As it grows, it sends it taproot down into the shallow soil until it finds a crack in the limestone. The taproot can reach the water and soil to support its life during the hot dry months of June and July. A truly amazing plant.

Thank you for joining me on my tour of the glade...I hope you enjoyed the coneflowers as much as I did? It's a special place, beautiful in a unique way. If you want to know more or if you plan to be in Tennessee ...go here for a list of glades open to the public. I know you'll love them, too.

Cedar Glade: The April Visit, Part I

Hey there, is everyone ready for the official April visit to the Couchville Cedar Glade. It was a beautiful morning and we wanted to get an early start; rain was expected and you know what rain means in a glade...mud!

Last month, most of the glade was underwater and

dotted all around with water tolerant spring wildflowers. (Leavenworthia stylosa)
The sky was gray and it was chilly...late winter in the Central Basin. The green of Juniperus virginiana was prominent.


Here is the same shot a month later. (click on any photo to enlarge)

I don't know about you but, wow comes to mind. All the marvelous green and a wonderful blue sky. It was muddy, but not sticky gooey mud!


We'll be back to this very spot in May...but for now let's see what else the Glade has in store for us!

As you enter the Natural Area we pass through a grassland meadow. The grasses have greened up nicely. Later in the season we'll clearly see Little Blue Stem grass and other native grasses.



The trail is a mile loop through a different landscape then most of us are used to seeing...There is exposed limestone with native shrubs and trees that you may have in your garden...but here you'll see them in their natural habitat. Keep your eyes open for some surprises.


The green shrubs are Hypericum frondosum (Golden St John's Wort) and Rhus aromatica (Fragrant Sumac) both in my garden. They have lovely yellow blooms. The Sumac's not in flower or bud in the glade, but I have buds at home. My garden is a less harsh environment and a few weeks ahead of the glade.

Here is a closeup of the Rhus, check out those beautiful leaves.... Do they look familiar? Rhus is a second cousin, twice removed from its rather foul tempered cousin, Poison Ivy, and not at all an allergic agent!


The Hypericum frondosum or Golden St John's Wort is everywhere in the woodlands. Not yet ready to bloom, but looking good with its soft green color.


Just a bit more greenery from the Red Cedar-Hardwood Forests that are often found near Cedar Glades. The soil is deeper and inviting to pioneer trees like Red Cedars.




More exposed limestone on the trail, We leave the wooded trail and turn the corner....to arrive at this open field of shallow soils, exposed limestone and endemic plants. This is the glade or barren. If you look closely, you can see the wildflowers; some emerging, some budding and others blooming. This is the home of Tennessee Coneflower and....


SURPRISE! Verbena canadensis (Glandularia canadensis) growing in its native habitat. Homestead Purple is the hybridized form of this extremely hardy native. The sweet little white flower growing with it is Glade Sandwort (Minuartia patula). Both were growing everywhere, including the middle of the trails. Talk about tough plants.

Many yards within a mile or so of Couchville Cedar Glade have glady conditions; not much lawn, instead they have large stands of Glade Sandwort and Rose Verbena. Really lovely.

Another glade native is Glade Phlox (Phlox bifida). It's just beginning to bloom.

I expected the verbena and sandwort but was completely surprised to see Shooting Star (Dodecatheon meadia) hanging out in the neighborhood. This was a first for me...I love Shooting Star, but have only seen it in cultivated gardens. I was thrilled to see this plant! This is why we have to continue protecting native habitats...but I shall leave that subject for now....




If this is your first visit you might not know what a Cedar Glade is and I quote myself here from an earlier post:
"... now a cedar glade is clearly a rocky, gravelly or grassy opening that might be surrounded by red-cedar forests or red-cedar/hardwood forests."

In a glade, you'll find 300 million year old limestone either exposed or close to the surface...and growing there are plants that have adapted to harsh conditions...very wet in the winter and bone dry in the summer. You wouldn't think anything can grow here but it's teeming with life!

I love this mosaic composition...and so does the Glade Sandwort.


Here is a big picture shot of Glade Sandwort...happy in full sun, limestone and shallow soil.




Sandwort growing in shallow soil on exposed limestone with emerging coneflower.The Red Cedar-Hardwood Forest surrounds the glade. The boulders were very inviting and seemed a good place to rest and think.



As we walked closer to the rocks, I was lost in thought; appreciating the stark beauty and wondering again, what early Tennessee pioneers felt about this difficult land.... my husband woke me from my daydream when he said, " Gail, look at this!" I looked up to see this!


Quite the surprise isn't it!

It had to be a group of scouts who found all these bones! They honored the rules and didn't take them out of the park and left them there for all to see.

Speaking of the hand of man...this glade has only been protected since 1995. There is much evidence that this beautiful park was once used by us as a dumping ground...


It's hard not to appreciate nature...


and easy to be disappointed with human behavior that shows no respect for it.




There's more to see in the glade, shall we meet back here tomorrow?

So Dear, Tell Me Again Why You Blog?

My husband asked me why I wanted to blog. He isn't a gardener so the need to share with other gardeners, talk about gardening or read about gardening doesn't appeal to him. But because he has other fabulous qualities (for instance, he hardly ever complains about my addiction to plants, never complains about picking up dinner when I have been outside all day and am too tired to pick it up myself, he doesn't care what I do to the yard and he made me an Inuksuk*) I will give his question serious thought and attempt to answer it.

Why did I want to blog? It's really simple, I was frustrated that I couldn't find anyone talking about cedar glade gardening. Don't get me wrong, there are wonderful websites with great information about cedar glades, but almost all are government sites or natural areas. Just google cedar glade gardens and see what I mean.

The problem was that none of them spoke directly to the gardener who wanted to honor the cedar glade conditions she had come to accept, albeit reluctantly. So I decided to start a blog that would talk about my experiences gardening and about cedar glades.

My hope is that others in the Middle Tennessee-Central South will find it helpful.

*an Inuksuk is singular for Inuksuit. "Inuksuit were stone figures placed on the temporal and spiritual landscapes by the Inuit people of Canada. Among many practical functions, they were employed as hunting and navigation aids, coordination points, indicators, and message centers."
