Witch Hazel Kool-aid

One of my many, many pet gardening peeves (which should be differentiated from the many pets that peeve me in my garden), is the manner in which the fiendish ghouls who create plant catalogues enlarge and enhance an otherwise insignificant flower until the catalogue reader (i.e. the gardener) is compelled to grasp frantically for the phone and credit card and purchase a dozen for their garden. Every Midwestern gardener who has ever drooled over a plant catalogue in the depths of a cold, snowy Winter could name at least one, if not several, horticultural mail-order firms that are notorious for the practice. Closeup, voluptuous pictures of Hybrid Tea roses are moderately tolerable, but the act of magnifying tiny asters or honeysuckle until  the gardener feels that he or she could utilize the flower as a scented and comfortable spare bedroom just isn't fair.  Heck, even the surface of male bovine manure looks interesting when viewed at a microscopic level, but it is still male bovine manure when viewed in normal size.

 I give you, as evidence of my dissatisfaction, the Witch Hazel. Witch Hazels are hailed as the first blooms of Spring in many areas, flowering boldly on leafless stems in late winter. Each flower has four slender strap-like petals that are always pictured everywhere as the most glorious, showy flower in all of Creation. Every gardener just has to grow one in our gardens, right?  Especially those gardeners who haven't seen anything but mist and snow and ice for the past three months?  For years, I indulged in the fantasy of adding one of these scented beauties to my garden so that I could advance Spring forward into Winter and enjoy the simple beauty of natural flowers without resorting to artificially forcing bulbs or flowering shrubs. Pictures such as that at the left drew me in; enormous, frilly, impossibly delicate, bright blooms that look as if they would cover your hand. I was told time and again that Witch Hazels were difficult to grow in Kansas, and in support of that wisdom, I admit that I have yet to find a surviving specimen in a public garden in this area.  But I couldn't call myself a gardener if I didn't at least try.  In fact, I failed the first time I attempted to overwinter an expensive specimen, but I'm now into my fourth year of survival of a 'Jelena' (Hamamelis x intermedia 'Jelena'), and I couldn't be more disappointed at the reality of the bush.
  
Garden writers are no better than garden photographers in describing that reality for us.  The late Henry Mitchell, in One Man's Garden, stated "Nothing equals the hybrid Asian witch hazels for delight in late January-February-early March, depending on the weather....Usually, as in the variety called 'Jelena', they are orange-bronze in effect and surprisingly showy."  Showy?  I, for one, loved Henry Mitchell's writing and use of language, but he failed me this time. If you, the reader, will think back really hard, you'll realize that you have never seen an entire, whole Witch Hazel bush pictured in bloom in a book. They are pictured in toto only as an example of nice fall foliage color. The real reason the blooms are always pictured in closeup is that in reality they are only 1-2 cm long and are practically invisible from 3 feet away regardless of the bright color. The same flower, without cropping and enlargement, actually is better represented by the picture at the right, a sad and impossible standard to worship, even for a winter-starved gardener.  If one has to use a magnifying glass to view a flower in the garden, the overall landscape benefits of the plant are dubious, at best. 

So, I don't know how many of you grow Witch Hazel and would agree with me, or how many have swallowed the Kool-aid whole and feel that I'm just a crotchety old gardener who expects too much and gripes too loudly.  But I submit to you that if we are all being truthful with one another, we would admit that Witch Hazel wouldn't be worth growing if it bloomed in June instead of February.  And in full disclosure, I am suspicious that my Witch Hazel is not actually 'Jelena'.  The blooms of my bush are more yellow than other pictures I've seen of the variety, and up till now the fall foliage has been uninspiring.  The most likely explanation is that I was sold a mislabeled plant and didn't obtain the variety I sought.   Which brings up another pet peeve.....

Shrubs for your Soul

For all those gardeners who haven't happened upon it, there is a new online gardening magazine titled Toil the Soil at BestGardenBlogs.com.  For the first (and free!) issue, I wrote an article in it about Plains-adapted flowering shrubs for MidWest gardeners titled "Shrubs for the Soul."  I thought I should post the text and some of the pictures here as well on my own blog, since the clickable pictures should be better quality here.  It may take a couple of parts:

Shrubs for the Soul:  Plains-adapted flowering shrubs for the winter-weary Midwestern gardener.
 
 Imagine that it is February 1st, 2011 and the biggest winter storm of the decade is throwing snow and ice at your windows and creating six foot high drifts around your shrub roses. You are a gardener in the Kansas Flint Hills who hasn’t seen a single sprig of green plant life for 2 months and your soul aches for any sight of a cheerful spring bloom. You are also an amateur writer who is trying to choose a topic for a new garden magazine and you’re under a short deadline. I’d be willing to bet my entire mail-order plant budget that eighty percent of you would choose, under those circumstances, to write about the spring-flowering shrubs that your heart pines for. The other twenty percent might write about either starting seeds indoors or about forcing spring bulbs, but I’m a conventional kind of guy, so I’ll stick with the cliché.

Here in the Flint Hills of Kansas, shrubs that can survive our cruel, arid Zone 5B winters, flower reliably in the soggy clay abetted by the April and May downpours, and then hold on steadfast through the hot dry summers, are indeed few and far between. Some spring shrubs counted on for the earliest displays in some regions of the country, such as the Witch Hazels (Hammelia sp.), need more acid soils to thrive than we can usually provide in the Flint Hills. I have, for instance, a specimen of ‘Jelena’ witchhazel in my garden and it is seen seldom enough in the area that most gardeners who visit either ask what it is or express surprise to see it. Those shrubs that do thrive in our soil and climate, however, are the pillars of Kansas gardener’s hopes in the Winter and provide the restoration of those gardeners’ souls each Spring. Eight intrepid shrubs that are well-equipped for the Kansas and Great Plains climate are:
  
'Meadowlark' Forsythia
Forsythia sp: Everyone with any gardening experience in the MidWest knows that Forsythia is going to be on this list, so we might as well get it over with early. Many varieties of Forsythia grow and perform very well here, and in fact, Manhattan, Kansas and the surrounding towns are pretty well covered in early April with the pastel combination of yellow Forsythia shrubs and pink Redbud trees. Some varieties of Forsythia can sustain damage from the more extreme winter temperatures of the Flint Hills, so it is useful to search out and plant the hardier varieties. Forsythia x int. ‘New Hampshire Gold’ (USDA Zone 4-8) is a mounding, arching shrub to about 5 feet tall that has reliably flowered every spring for ten years in my current garden. I tend to prefer the less brassy yellow tones of the newer Forsythia ovata ‘Meadowlark’, however. ‘Meadowlark’ has a taller and stiffer form to about 6 feet tall and the blossoms are much larger and showier than ‘New Hampshire Gold’. ‘Meadowlark’ was developed in a collaboration between the Arnold Arboretum and the North Dakota Agricultural Experiment Station and is widely proclaimed as the hardiest of the forsythias (Zone 3-8), with buds resistant to cold damage to -35®F. Variegated Forsythia varieties, such as ‘Fiesta’ are planted here in hopes of a better display in the off-flower seasons, but they often suffer damage when fully exposed to the hot prairie sun and buds are not as reliably cold-hardy as the varieties previously mentioned.

Magnolia stellata
Magnolia stellata: One of the earliest flowering shrubs in my garden is Magnolia stellata, the Star Magnolia. I know that some gardeners in other zones or climates might think of this magnolia as a tree, but it definitely remains shrub-sized everywhere I’ve seen it in Zone 5. . I have cultivar ‘Royal Star’ which grows to around 10 feet, but other larger M. stellata cultivars are also available. But, regardless of ultimate size, this beauty is a god-send for early fragrance. I’ve never been particularly excited about the smallish 3-inch white blossoms against the bare branches, not like I am with some of the larger and more colorful magnolias, but the Star magnolia more than makes up for it in scent production. The survival of this one has encouraged me to try a few other of the hardier magnolias, including ‘Jane’, one of the “Little Girl” hybrids from the U.S. National Arboretum, and Magnolia acuminata ‘Yellow Bird’, a recent introduction from Monrovia. Both are reportedly hardy to at least Zone 5 but they are too young to be certain performers in my garden.

Syringa sp: Lilacs of all species and types are well-adapted to the alkaline soils of the Kansas Flint Hills and are cold-hardy far beyond our region. They bloom early in April in Zone 5, and sometimes the earlier blooming cultivars can be burned by a late frost or even dusted with snow. Although the hundreds of Syringa vulgaris cultivars all do well,  Korean lilacs and newer cultivars such as ‘Josee’ also thrive in the Kansas sunshine.  And the scent!  What would the scent of a Kansas spring be without Lilacs? 

Lilacs 'Wonderblue', 'Yankee Doodle', and 'Annabelle', left to right
the next week or so, I'll post the rest of the article, including a discussion of honeysuckles, viburnums (yes, in full sun!) and mockoranges.  But not right away, because I've got other things to touch on first!

Healthy Prairie Harvest

One of the first Griffith Buck roses I ever grew, and still one of my most cherished roses, is 'Prairie Harvest'.  I've mentioned her before in this blog, but she deserves her own little moment alone in the spotlight. In fact, for Midwestern gardeners who seek out the Buck roses, 'Prairie Harvest' is a "must have" rose.  Hardy yellow roses are difficult enough to find for Northern climates, let alone hardy yellow roses that are also ironclad healthy.  'Prairie Harvest' is one of my healthiest roses and the light green, glossy foliage is a nice contrast with that of the Rugosa clan.  I never spray fungicide on this one and the perfect foliage holds on through August with minimal leaf loss, little blackspot, and no mildew.

A young, two year old 'Prairie Harvest'
Although the foliage IS spectacular, 'Prairie Harvest' is my favorite of all the Buck roses because of the blooms. Unlike many of the Buck-bred roses, these hybrid-tea style, 4 inch blooms hold their form well, not quickly opening flat or showing their centers as many of the Buck's are prone to do. The rose is fully double with 40-45 petals, and quick to repeat, with continuous single flowers and floribunda-type sprays throughout the summer and fall.  But it is the soft-yellow color, more potent in the center and fading to white on the edges and as it ages, that makes this rose stand out for me.  The yellow-white blend of the newer acclaimed floribunda 'White Licorice' reminds me of this rose. The color mixes well in the garden, not like the gaudy pink of 'Earthsong'.  It also has a nicer, neater bush form than 'Carefree Beauty' (one of its parents), and it is just as healthy and hardy here in my Flint Hills garden as either of these other well-regarded Buck roses, solidly cane-hardy in my Zone-5 garden.  In fact, the overall form of this rose is far better than most modern hybrid teas, with a nice vase-like four foot tall by three foot wide shape at maturity.

Prairie Harvest was released in 1985 and is officially classified as a shrub, although I would have said it is closer to the Grandiflora clan in its overall form.  The Iowa State University website on the Buck roses describes it as "barium yellow," whatever that is.  To me, this rose is honey-yellow, fading at the edges to white, and in cold weather it may have just a touch of blush pink at the edges.  The fragrance is moderate and sweet, described as "fruity" by some with noses who are undoubtedly more discerning than mine.  Both the yellow center and the fragrance undoubtedly are from 'Sunsprite', a Gamble Fragrance Award winner and the second parent of  'Prairie Harvest', but in my garden, as much as I love bright 'Sunsprite', 'Prairie Harvest' is by far the healthier and hardier of the two.

'Prairie Harvest' with a little Fall blush
I'm sorry to finally write this post, because I know it'll send half the rosarians reading it into a frantic search for a source for this rose, but sometimes, just sometimes, everyone needs a little nudge towards perfection.
