Labeling; well, I tried

A recent post on Gardenweb.com reminded me to check up on an experiment I tried a summer back in my garden.  In 2009, when my garden was on the local annual Garden Tour, I put a little time into labeling most of the roses.  Knowing that the zinc/soft pencil labels are notorious for fading, I decided to spray some of the labels with Helmsman Spar Urethane, chosen because "it forms a protective barrier against rain and moisture" and "the enhanced ultraviolet absorbers found in Helmsman reduce the graying and fading effects of the sun."

Well, you can see the results below.  The three labels pictured were all created and put into the garden in Spring, 2009 and remained there, so they've been exposed to two Springs, two hot Kansas Summers and one very cold Kansas Winter. The urethane coating did decrease the fading, but there was a drawback, as you can see in the third picture;  at some point the urethane flaked off a number of the labels leaving them worse than before.  I'd say about 50% of the labels look like the first picture at this point and the other 50% look like the third; or worse.  We'll call this experiment a gigantic fail.

Coated Label at 1.5 years

Uncoated Label at 1.5 years

Oops;  flaking away...should say "Buck Rose" at the top

Back to the drawing board, eh?  Must make a note to redouble my efforts to keep plant locations listed on the computer....and backed up.

Survivor Lessons

Last weekend I was puttering around the garden, doing all the usual things, pulling weeds, deadheading roses, sobbing over some drought-stricken perennials, and then, stumbling dehydrated up the cement stairs from the back garden beds, I came unexpectedly face to face with a shining example of eternal truth.  The truth that, as said best by a character in the now ancient movie classic Jurassic Park, "Life always finds a way."

Growing in a quarter-inch deep deposit of wind-blown organic debris, surrounded below, and to three sides by limestone or cement, exposed to the burning southwestern sun, stood a small volunteer lavender plant in perfect health.  Never mind that we hadn't seen any appreciable rain for a month, never mind not a sprinkle for a week, this little baby plant had germinated and grown on nothing but air, limestone, and a little organic dust.  About one and one-half inch tall and wide, its entire time on this planet must have been as precarious as a trapeze artist without a net.  One wrong step by a dog, a too-forceful gust of hot wind, a wandering herbivore, and the time of this plant would have been over. 

There are many lessons here for all of us, lessons both of gardening and of how to live our lives.  I'm sure that others can take their own thoughts from the image above, but I, for one, was struck first by this blatant demonstration about wants and needs; that we must, for our own sakes, find an environment that contains everything needed to prosper, including shelter, moisture, food and sunlight.  And yet the best survivors don't really ask or expect much more than that, as this little plant was telling me.  Lavender is surely adapted well to the Kansas climate, as many Mediterranean plants are, but scratching out a living on my cement steps was not something I would have predicted for it.

The little trooper also shows us a lesson about going with the flow. I don't know how long it has been growing, probably no more than a few weeks, but it started life in the middle of the hottest, driest days of summer and then found the strength and moisture, from dew, from translocation through the concrete, or from the very air, to keep growing. It scoffed at the burning sun and the 110 temperatures. It held fast to the rock despite the searing Kansas summer winds. It protected itself by drawing around it the little fuzzy gray-green coat common in lavenders.

Can we be as strong, we gardeners, we humans?  To grow without over-ambitious expectations, to survive in the face of adversity, to cling to the wonder of life? Are we all ready to take the chance, to take the leap of our lives and then to hang on with all our God-given gifts and just be thankful for the sunlight?  I suppose, for my little lavender friend and for each of us, that time will give us our answer.    

White Tower

My Sweet Autumn Clematis bloomed in September this year instead of late August, keeping me waiting a bit for the annual wrapup of fragrancy in my garden, but bloom it finally did.   I worried about its health all through the spring, but it nevertheless returned to sweeten the September air.

Although most of the summer it merely provides iron-clad green foliage, and after flowering silvery, plume-like seed heads will decorate it, every gardener should grow Sweet Autumn Clematis merely for the few weeks of unmatched fragrance it provides.  But talk about your confused Latin nomenclature!  Sweet Autumn Clematis has been variably listed, and can still be purchased as Clematis terniflora, C. paniculata, C. maximowicziana or C. dioscoreifolia.  The species most commonly grown in the United States, and listed by the USDA as C. terniflora, is native to Japan, although one source says that C. paniculata is a separate but identical species native to New Zealand. 

Whatever you want to call it, I grow Sweet Autumn Clematis on an 8 foot tall wire cylinder in the center of my garden, pictured above as taken on a recent misty morning.  I question the oft-repeated information that C. terniflora is hardy to Zone 4, because my history with the plant has been to grow one, lose one, have a volunteer come up in another spot, and then had that volunteer cover the wire tower for three years running until this past winter, admittedly a bad one, when it was killed back to the ground.  I waited patiently this spring, hoping to see signs of life and knowing that clematis often take some time to put leaves on their seemingly dead vines, and just as I was about to give up and was ready to find and plant a new one, some nice green shoots popped up from the ground in the center of the tower. Luckily for me and my garden, Sweet Autumn Clematis grows 20 feet in a single season and blooms on new growth, and it recovered 2/3rds of the trellis again before blooming this year.  In the Flint Hills, it seems to be completely free from disease and the flowers, though small at one inch across, are so fragrant with a rich vanilla scent that this single vine perfumes my entire garden for weeks.  To stand downwind of this central white pillar is to overdose on the scent of heaven.

Although I understand that the Internet is not always a reliable source, it sometimes pays to do a little reading anyway, and in my readings about this vine, I discovered that clematis is in the buttercup family (a neat little factoid for cocktail parties that I never attend anyway) and was called "pepper vine" by Western pioneers and used as a pepper substitute since true black pepper was a rare and expensive commodity for them.  I don't know which clematis would have been carried on the wagons westward, but the entire genus supposedly contains essential oils and compounds that irritate the skin and mucous membranes and can cause bleeding into the gastrointestinal tract if ingested in large amounts.  Thankfully, since I don't like black pepper anyway and the long-suffering Mrs. ProfessorRoush has indulged me by limiting its use in her cooking, I won't be tempted, come the Revolution, to try this dangerous substitute.

It just occurred to me that I've blogged on two white fall-blooming plants in a row.  Maybe I should start a White Garden and create a prairie Sissinghurst out here in the middle of Kansas.  What a fantasy, me and Vita (Sackville-West), gardening together at last.

Prairie Poinsettia

I'm bad about letting volunteer plants grow at their whim if they look like they might turn out to be something worthwhile, but sometimes it pays to grow a few weeds to help you cheat through the dull days of the garden.

A native Kansas annual that grows everywhere I choose to allow it is Euphorbia marginata, or "Snow-On-The-Mountain."  Look at the single volunteer at the left blooming in late August in front of the bright red crape myrtle Lagerstroemia indica ‘Centennial Spirit’.  Now, I ask you, what better plant combination could you want then this three foot tall spurge growing in front of the five foot tall crape?  I counted across the garden this week and I've got over 20 of these volunteers spread out making bright spots over the beds.  And look at the flower detail in the picture below.  In early September, after a summer's drought and when every other plant has insect or wind damage to half its foliage, look at the crisp, clean margins of these flowers and the white-margined foliage.  Green and white may not be everybody's cup of tea, but surely few would argue against the impact of this plant at a time when little else blooms.  This relative to the poinsettia has a  prolonged bloom period, commonly open from August to October.   As an added benefit, this is not a tough plant to pull out from where you don't want it; it may love xerigardening conditions, but  the taproot slides right out of the soil when you tug the stem.  Just don't get the sap on your hands if you're sensitive.

Snow-On-The-Mountain contains a milky sap that is said to be as irritating as poison ivy on exposed skin.  Since I'm immune to poison ivy (how neat is that for a gardener?) and Snow-On-The-Mountain doesn't bother me either, I can't confirm the comparison.  One reference said that cattle won't graze on it and if E. marginata is dryed along with hay it can cause sickness and death in cattle.  Another says that all parts of the plant are poisonous, so take care with children and don't eat it in your salads. 

Now some, of you, I know, are thinking, wait, I have "Snow On The Mountain," and it doesn't look like that.  Aegopodium podagraria 'Variegatum', is an invasive ground cover that is also known as "Snow On The Mountain" or "Bishop Weed."  It's a variegated perennial, grows well in shade, and doesn't have the milky sap, so you can't confuse the two when you see them .  Just another reason for gardeners to bite the bullet, learn genus/species nomenclature and ask for exactly the plant they want when ordering.  Seeds are available from several select sources, including Jefferson's Monticello, but look especially for a cultivar named 'Summer Ice' if you can find it, because not all the offered plants have the best bright white margination.

Since my native Euphorbia marginata is identical to 'Summer Ice', I guess I'm just one of the lucky ones.
