Nice & Naughty Knautia

Knautia macedonia

Occasionally, one has a nice plant that does well in your garden but is overlooked by many gardeners.  Such plants often serve the triple purposes of a conversation piece, an educational opportunity, and a bragging item.  Such is the place occupied by Knautia macedonia in my garden.  I've grown it for years in my front landscape, or rather, it has grown itself; self-seeding, carefree, drought-resistant, and pest-free.  I planted it, it grew, it spread, and I simply enjoy it and remove the dead stems each Spring.  It has survived years of neglect, drought, and, this year, an almost record amount of rain.  Frankly, although sometimes I have to point it out to visitors, I wouldn't attempt a garden in the Midwest without it, even though the common name of the genus, "widow's flower" gives me a bit of pause.

I learned of Knautia macedonia years ago from Lauren Springer Ogden's first book, The Undaunted Garden.  Mrs. Ogden had a section at the end of the book highlighting, if memory serves, about 50 plants that were well adapted to her arid eastern border of the Rockies.  Knautia macedonia was one of those and I remembered her description when I saw it for sale at a local nursery.  The photos here, I believe, represent the original species, although I think it used to be more scarlet than it seems to be now.  Or perhaps I was just younger and the colors were correspondingly brighter.   At one time, I also grew K. macedonia 'Mars Midget' in the same area.  'Mars Midget' is a shorter cultivar with this overall color, but with whiter stamens.  I don't know if it survived, or perhaps interbred with the species to give me a bit of a darker red hue.  There is another commercial selection available, 'Thunder and Lightning', but it doesn't appeal to me because it is one of those modern monstrosities of plant selection with variegated leaves combined with a more puke-purple flower.  Yuck.

Knautia grows on the northeast side of my front border, at the feet of bright red Rugosa hybrid 'Hunter' as you can see above, and it blooms for most of the summer before dying back to a reliable perennial base.   The smaller flowers in the photo above are all K. macedonia, the brighter red larger flowers are 'Hunter', and the mauve-red blobs at the left of the photo are 'Kansas' peonies that are past their prime.  A closer photo of the Knautia macedonia mishmash is shown here at the left.  The plants are relatively short, but the flower stems rise high above the border and sprawl carefree around all their neighbors.  Gardeners' who like Knautia must be willing to tolerate a moderately disheveled but predominately pretty lass who is a little loose with her limbs and who is prone to procreate at random places throughout the garden.  ProfessorRoush most definitely falls into that class of gardener.  Also self-seeding and equally flirtatious, but not yet blooming in the same area, is my bright red, square-stemmed  'Jacob Cline' Monarda that will later add more bright red to this scene sometime during the second flush of 'Hunter'.   Red without end, amen.
 

Buffalograss II

Buffalograss (Buchloe dactyloides) is described in the texts as a gray-green, fine-textured, warm-season grass.  Translation:  you're never going to get a dark green lawn out of this grass (so quit trying!) and it won't green up or start growing until the frosts end here in Kansas, usually around May 1st.   It is, of course, a major component of the short-grass prairie to my west and it thrives both south and north of the Flint Hills.  It is hardy from zones 3-9, and can be found growing naturally from Canada to Texas.

The native species grows 4-6 inches tall, with flowers that top the foliage slightly.  It is quite tolerant to drought and withstands some extensive repeated trampling by heavy quadripeds or bipeds. It is proclaimed as one of the "finest grasses for arid regions" in Greenlee's Encyclopedia of Ornamental Grasses. There are several breeding programs that are directed at decreasing the overall mature height and increasing the green-ness of this grass, in an effort to develop a perfect turfgrass that never needs mowing, but those goals are still just a far-off dream.  A major obstacle in the commercial acceptance of the grass is that this is a diecious species (with male and female plants), hence the formation of the flowers, and seeded varieties will always have the seedheads to mar (or improve depending upon your point of view) their appearance.  There are, however, female-only cultivars that can be established by vegetative plugs, sans flowers.  'Legacy' seems to have the lead in plug-grown varieties, while 'Bowie' is the up and comer for seeded types.*

Whether or not the flowerheads and subsequent seedheads offend your aesthetic senses tells a lot about the inner gardener in each of us.  Some gardeners will trim their buffalograss lawns at the first sign of a flower (usually these are old men with carefully trimmed topiary scattered around their gardens).  The same group will fertilize their buffalograss on a weekly basis in an effort to give it that "deep-green" look.  These people should not have started a buffalograss lawn in the first place.  At the other extreme are Birkenstock-wearing wild-eyed environmentalists (BWWEE) who think that the blue-green hue of the grass and the yellowish-brown seedheads were the carpet of the Garden of Eden, and who are prone to doff their clothes without warning and stretch out au natural on the sun-warmed buffalograss.  Mrs. ProfessorRoush tends towards the former and I must admit my sentiments lay towards the latter, so there is a bit of a marital clash on that point, thankfully limited to telling me to get off the lawn and go get some clothes on.  Lauren Springer-Ogden, touts buffalograss as a lawn in her book  The Undaunted Garden, and recommended placing small spring bulbs in the lawn to brighten up the beige appearance after winter.

A big advantage of a buffalobrass lawn, in my estimation, is that you can forever give up overseeding or patch-seeding.  Buffalograss spreads from rhizomes as you can see from the picture at the edge of my blacktop at the right, and it will fill in bare spots within a season if minimally cared for.  I've had large areas develop sparse grass in my buffalograss lawn, especially when I was learning to care for it, but they are easy to entice the grass to fill in with a minimum of treatment and fertilizer.

By the way, you may be wondering, is it "buffalograss" or "Buffalo Grass" or "buffalo grass?"  I don't care and the sources I've looked at all are different.  The latter two don't look right to me, so I'm sticking with buffalograss.  Just don't call it buffalograss to an Aussie, because they will think you're talking about St. Augustine grass.

Somewhere out there, this grass will continue to grow in acceptance despite the clamor of all those who want us to grow fungus-ridden Kentucky Bluegrass here in the arid Plains.  I'll never forget standing in line behind a priest several years ago at a very large and well-regarded local nursery in Topeka and listening to him ask a clerk about how to start a buffalograss lawn.  His thought was to decrease the mowing and care needed by the volunteers of the church, a worthy goal in my estimation.  The know-it-all clerk told him that it was too wet in Topeka to grow buffalograss(!) and what he really wanted was a K-31 fescue lawn and she proceeded to sell him a large bag of K-31.  And here I was behind him, just dying to blurt out that I had a buffalograss lawn, and a decent one in my eyes, just a scant 50 miles west.  I kept my own counsel, but a small part of me has always hoped that the clerk's soul shriveled up a bit at her act of buffalograss denial in front of the priest.  

Crocus cavils

Yesterday, notwithstanding the six inches of snow we received 4 days earlier, the temperatures turned a balmy 76F and my giant "Dutch crocuses" (heavily hybridized Crocus vernus) suddenly bloomed.

Crocus 'Remembrance'

I wait every year for these crocuses to be those first prolific little flowers to brighten up my beds, but in truth, I confess that I'm not overly fond of them.  Now, before my readers tune me out entirely, I admit that my misgivings about Spring crocus are few and these little darlings do have their fine points, some of which are not widely known.  I know for instance, from Louise Beebe Wilder's writings, that Dutch crocus have a really nice scent if you lay down on the ground at their level, and having done so at risk of being observed and judged harshly by the neighbors, I can confirm Ms. Wilder's observations.  Gardeners in general seem to rarely pick these 6 inch beauties and raise them up to sniffing level as they would do with most other flowers, so those who haven't read Wilder do not seem to know this fact (I'll leave that alone now since this is not the time or place for garden literature snobbery).  Perhaps picking these diminutive blooms smacks too closely to plant abuse for many gardeners, but however you go about it, give them a sniff.  Children, as noted by the esteemed writer Henry Mitchell in The Essential Earthman, seem to be particularly prone to pick these giant colorful blooms and thus are often more familiar with the scent of these beauties.  The quickest road to hell, quoting Mr. Mitchell, is to "growl at a child for picking crocuses."  Henry seems to share my general ambivalence about crocuses though, calling them "vulgar" and recommending more stringent measures ("a tub of boiling oil") for children who pick irises or lilies without permission.



Crocus 'Pickwick'

 One of my minor complaints against Dutch crocus is that the Kansas winds tear the blooms to pieces quickly if they are not in a sheltered spot.  Many garden writers, such as Lauren Springer in The Undaunted Garden,  make a strong case for planting crocuses freely in warm season grass lawns such as the buffalograss that closely surrounds my house, but I've found that the crocus survive to please me only in my cultivated beds sheltered from the prevailing Spring winds of the Flint Hills.  Shortly after moving to this land, I planted over 100 Dutch crocus in the center patch of my circular driveway, but their blooms survived on this flat plateau only a day or two, if that, before the winds swept them away. The overall mass effect also dwindled over five or so years to nothing, despite my efforts to refrain from cutting the grass in this area until early summer.  I surmise that between the summer heat and the surrounding prairie grasses, they just didn't compete well in this area. When the flowers don't stay around, crocus are just not worth the planting efforts.

I'm sorry that I'm not a connoisseur, but I grow only the most common commercial varieties, the old deep purple 'Remembrance' and the striped 'Pickwick'.  I'm not fond of the common yellow crocus 'Yellow Mammoth', because this crocus is a little too orange or brassy for my tastes, like that of the daylily 'Stella de Oro', nor do I grow the white forms of Spring crocus.  As the result of choosing only the darker colors, my crocus don't compete well for attention against the gray remnants of last year's mulch unless you're looking for them, and that drawback is all entirely my fault.  I do look for them though, every year, to confirm that Spring continues to advance towards me and to ease me gently into the massive displays of daffodil and forsythia that come shortly afterwards.  Short-stemmed, short-lived flower or not, what would Spring be without a few gaudy crocuses in the garden?

The Undaunted Garden

I had occasion recently to re-read Lauren Springer's (now Springer-Ogden) first text, The Undaunted Garden.  What a treasure trove it is of gardening information for the Kansas gardener beset by wind and storm and ice.

Subtitled "Planting for Weather Resilient Beauty," it remains one of the most readable and beautifully illustrated garden-related books I've ever read.  First published in 1994, the text and photographs were all created by Ms. Springer in an obvious labor of love and belief in what she was producing.  It has become a classic garden read, first, I believe, because the writing is aimed not at the highbrow level of garden designers, but at the dirt's-eye level of the struggling gardener.  Second, the lessons for plant selection and plant survival on the Great Plains are well thought out and presented in logical order and in language easily understood by all levels of gardening experience.  Lastly, Springer's Undaunted Garden heralded her embrace of native plants, and further yet, her recognition of "adapted" plants as a means to transform gardens in the prairies and Colorado foothills, beginning her reputation as the premier garden designer and writer she has become.  Until this book, I don't think that I had ever seen the concept that one can create a garden that smiles through the worst of a climate by not planting just with natives, but by extending a home to plants that are adapted to similar climate conditions, whether those plants were found bordering the Mediterranean or in Australia.

I've always sympathized with her opening thought "I don't understand the concept of the low-maintenance garden...to desire a garden that requires no time spent except the occasional stroll in well-laundered clothes is like having the most beautiful and appetizing food laid out on a table before you and not wanting to take a bite."  Ms. Springer invites us in, and then teaches us, with named examples, to select plants that survive the extremes of drought, hail, wind, and driving rain, all while keeping an eye on the design of a bed or garden.  My favorite chapter, Roses for Realists, increased my own interest in Old Garden and hardy roses, to which I was especially susceptible after only a few short years of beginning gardening where I learned that Hybrid Teas were perhaps not the best choice for the Flint Hills climate.  And the last section, Portraits of Indispensably Undaunted Plants, which is a glossary of Plains-adapted plants, provided us all the tools we needed to reform our own gardens.  In reviewing that section, I found that I have tried most of the plants highlighted for sunny exposures.  It was the first time, for instance, that I ever heard of Knautia macedonia, which is now a mainstay of my front border.      

I see from the Amazon.com site that a revised second edition is coming out soon, expanding both the photographs with new additions and increasing the number of highlighted plants from 65 to 100.  Although the bibliophile in me will always prefer my first edition hardcover, I may have to fork out the money from my gardening budget to get the revised edition as well.  I can always consider another 35 recommendations for my garden from an established expert, particularly one writing, it seems, especially for my Flint Hills weather.
