Sugar Tip Rose (of Sharon)

Wow, ten days since my last post?  Time flies when my attention drifts and life runs quickly.  My wandering affections for the garden were jerked back in line yesterday as I was mowing, however, by a glimpse of this little bush, a beauty shyly screaming for attention against the prairie backdrop.  Stopped the mower short, I did, and jumped off just as quickly to snap an iPhone picture or three.

This is Rose of Sharon 'America Irene Scott', otherwise known in the nursery trade as Sugar Tip®.    I bought her at a big box store this spring as a filler for the center of a new bed.  I was actually a little reluctant to purchase her, not because of cost or condition, but because I rarely like the flower colors that are commercially available with variegated foliage in many species.  One of my many pet peeves (which should be distinguished from the peeved pets that are my patients) is that breeders so often ruin a great flower trying to "improve" it by adding variegated foliage.  I was also afraid that the pink tones of Sugar Tip® would be a bit pale and uninspiring.  I brought her home, nonetheless, hoping that the deer would leave her alone despite her appetizing appearance.

I was, I now think, flat wrong this time to cynically doubt the marketing savvy of the horticultural world.  She's a small bush at the end of her first summer, only 2.5 feet tall and a little more slender, but Hibiscus syriacus Sugar Tip® is blooming her young limbs off, and the double blooms are sufficiently pink to perfectly complement the green and cream foliage.  I can't wait to see her in full bloom at her mature stature of 8 feet X 6 feet.  The petal color is of that demure, embarrassed pink tone best seen in the early spring in roses such as 'Maiden's Blush', otherwise known as 'Cuisse de Nymphe'.   The French should market this variegated Althea as  'Cuisse de Nymphe Dans la Dentelle';  "Thigh of a Nymph in Lace".  Qui, Mon Ami?

'America Irene Scott' was patented (US PP20579 P2) in 2009 by Spring Meadow Nursery Inc.  Hardy to -20F, 'America Irene Scott' was discovered, according to the patent, in a controlled outdoors nursery by Sharon Gerlt of Independence Missouri in 2001 as a natural branch mutation of 'Lady Stanley'.  I was, unfortunately, unable to learn more about Ms. Gerlt or why she named the plant 'America Irene Scott', but The Plant Hunter, a blog by Tim Wood of Spring Meadow Nursery, indicates that Ms. Gerlt may be an "amateur plants-person."   If she is indeed an amateur, she has a great eye for plants.

Please, Lord, make me as lucky in my own garden.

Anyonewanna Euonymus?

'Moonshine' Euonymus

No plant is more mundane, and likely more underused in our landscapes, than poor mispronounced, maligned euonymus.  It is the sad, simpleminded stepchild of gardening, spurned by buyers at big box stores and absent on the tables of many local nurseries, no prospect of noticeable flower or seed to improve its appeal.  It receives little press, little fanfare to announce either its planting or death, but euonymus , also known as wintercreeper, grows gamely on, a steadfast evergreen anchor of the bourgeois landscape.

Consider this blog entry a plea to resurrect its rightful place in the border, an entreaty to envision and enact a euonymus Eden, if you will.  I'm aware that it is contemptible in its commonality, boring in its banality, but it is hardy and hale and handsome in most sites.  The biggest and really the only failing of euonymus is actually the gardener's lack of imagination and foresight in cultivar selection and placement.

ProfessorRoush is not fond of coniferous evergreens, and may therefore subsequently be more open to experimentation with broad-leaf evergreens than perhaps your average mediocre dirt-digger, so I've grown several euonymus over time.  And while Euonymus kiautschovicus 'Manhattan' is the most common euonymus grown here in Manhattan, Kansas (the "Little Apple", as opposed to Manhattan, New York, the "Big Apple"), I've managed to avoid it like it was poisonous.  Hard to believe, but it simply is too bland, and grows too big, even for me.

'Emerald Gaiety' Euonymus

 I've long enjoyed Euonymus fortunei 'Emerald Gaiety', however, as a repeated fixture in my landscape, and I get entirely overexcited over E. fortunei 'Moonshadow', preferring the latter over the similar, but more trashy, 'Emerald 'n' Gold' cultivar.   'Emerald Gaiety' looks good for 50 of the 52 weeks in a given year, with lighter lime-green new growth in the spring and pink-tinged chilly edges in the winter, losing its appeal only at the end of winter when old leaves drop and brown over a few weeks.  'Moonshadow' provides an enduring and  beautiful specimen shrub on both sides of my entry walkway, glowing most brightly with the new growth of Spring.  Pruning either shrub is easily accomplished; just remove the fast-growing spikes each spring to keep it shaped and remove any non-variegated growth that occurs.  I've also shaped both cultivars with hedge-trimmers in early Spring, without any visible long-term detriment to their survival or appearance.

Right now they are quiet, mere notes in the landscape, their unobtrusive presence noted in the photo here by the white arrows in my front border.  They are obedient and calm, providing light contrast and balance to the bountiful flowering perennials among them.   In winter, however, THEY are the color, resistant green and white or green and yellow splotches to remind me that life remains in the garden despite the frigid temperature and frozen gales.  I depend on them, and ignore them, their devoted and yet fickle gardener, taking full advantage of their easy-going nature and their pest-free presence.

And "euonymus" is pronounced, for those who-wanna-know, if-you-must-know, "yoo-on-uh--muh-s".  So there. 

Hydrangea Heaven

Kansas gardens are living proof that not all hydrangeas are created equal.  I have always been a miserable failure at growing the more common blue or pink Hydrangea macrophylla, countless numbers of which I have purchased, watered, fertilized, protected, cursed and eventually mourned over.  My experiences with the more cold- and drought-resistant panicled hydrangeas (Hydrangea paniculata) have been much more promising, however.  Here in the dry sunny Flint Hills, these large shrubs are dependable focal points for the August garden.

 

 

 

'Limelight'

Without a doubt, the most floriferous display in my garden this week is 'Limelight' a fabulous panicled hydrangea that dominates its corner of the garden.  'Limelight' is an introduction from Holland patented in 2002, and it can make an enormous eight foot tall deciduous shrub in the garden, although mine seems to have maxed out at approximately 5 foot tall and wide.  The drought of the past two years seems to have worked in my favor this year, bringing the plant into a display that surpasses any other year.  'Limelight' grows in full sun and on an exposed site for me, completely unprotected from the Kansas climate, and it is cold-hardy to the tips.



'Limelight' Hydrangea

Some of the cone-shaped flower panicles of 'Limelight' are almost a foot long and 6 inches wide. They start out light lime-green and then fade to white and finally gain some pink tones in the fall, and the foliage seems to be resistant to insect and fungal damage here, although the leaves occasionally get a little crisped on the edges by the hot July and August sun.  I only regret that there is only a negligible fragrance and that the shrub is seemingly sterile in its environment, unattractive to bees and other valuable garden residents.

'Pink Diamond'

I grow several other panicled hydrangeas.  'Pink Diamond', pictured to the left and below, was labeled at purchase as a Hydrangea microphylla, but I can't find H. microphylla as a recognized species and online sources list it as H. paniculata.  'Pink Diamond' also provides a good floral display, and individual flowers turn pink quickly at the base of the panicles.  My 'Pink Diamond' shrub is about the same size overall as 'Limelight', and it sits at the opposite end of the same bed, forming white bookends at this time of the year for the other plants in the rest of the bed.

'Pink Diamond'

'Vanilla Strawberry'

H. paniculata 'Vanilla Strawberry' grows almost in the center of the same bed, and this has a much more subtle display than its show-off cousins.  At maturity, it is around four feet tall and wide, a little smaller than the H. paniculata cultivars, perhaps because it grows in the shadow of a towering  'Sweet Autumn Clematis' (seen to the left of the picture below) that also insists on trying to colonize everything within it's reach.  A note of caution is in order about the H. paniculata's:  Wikipedia states that hydrangeas are moderately toxic if eaten, with all parts of the plant containing cyanogenic glycosides.  Human beings sometimes try to smoke H. paniculata leaves, an often fatal action due to cyanide inhalation.  So, kids, don't smoke hydrangeas.

'Vanilla Strawberry' covered by C. paniculata

Although I've previously neglected to mention the garden usefulness of H. paniculata and other hardy hydrangeas as stalwart shrubs in Kansas, I would never leave them out of my next garden.  Right now, I've got high hopes for a yet small 'Pinky Winky' cultivar that I planted two years ago, although it has struggled in the drought and heat of its first two summers.  I'll also disclose that I've failed previously with H. paniculata 'Quick Fire', and with 'H. quercifolia', and 'H. quercifolia 'Little Honey',  but I think the latter native species deserves another try before I give up on it entirely.  It is supposed to have nicely-colored fall foliage that would be a good addition to my October garden.

  

Perfectly Placed Pyracantha

I don't know how most gardeners deal with "Firethorn" or Pyracantha, but over the years, I've found it a somewhat difficult plant to place.  It's a great shrub for xeriscaped landscapes in Kansas, and semi-evergreen to boot, but most cultivars are enormous when mature. Even the most refined forms get pretty large and can overwhelm a border.  The form most often recommended to gardeners, of course, is Pyracantha coccinea 'Lowboy', a specimen that only grows about 3 foot tall.  Be forewarned, however, this cultivar still spreads like its brethren, however, often to 6-9 feet in diameter.  My 6 year old specimen is currently about 4 feet tall by 6 feet wide and still spreading.

Pyracantha is best known to gardeners for the really nice Fall display of bright orange berries as shown in closeup to the right, but this is a good multi-seasonal plant.  It is said that the berries attract birds and provide food in the Winter, but they seem to last on the bush till late Winter, so it seems likely that the birds consume it only in desperation.  In Spring, the shrub bears small white flowers that are enticing to honey bees, and it keeps the leathery, dark green foliage well through the driest of Summers (like this one), often turning a bit burgundy with late Fall and Winter.   Most sources list it has hardy to USDA Zone 6, but I've never seen damage to my Zone 5B plants. There are times in early Spring when I think it looks a bit ratty, but it quickly shapes up as the weather warms.   There are some wicked thorns, of course, but that attribute just makes it a good choice for planting below the windows of a young daughter's bedroom, in anticipation of her teen years and the creatures that may be attracted to the gardener's abode at that time.  Nothing is better than a barrier of well-grown Pyracantha or a stiff shrub rose for cooling the ardor of a teenage boy.

I initially placed a 'Lowboy' into my back patio border in 2000, but it grew quickly to smother several surrounding perennials.  The thorns make this a plant you don't want to have to thin on a yearly basis, either.  Then, in 2005, I noticed a small trail leading under the shrub, and in late winter, as the leaves thinned out, I realized that while Pyracantha is impervious to deer, the prairie pack rats think that it is a good foundation for a communal dwelling.  Since I detest the little creatures, providing them shelter approximately 10 feet from my back door was not a favorable idea, so I thinned and shortened the spiny branches at some risk to my dermal covering and then burned them out, protecting surrounding plants as best I could by a constant spray of water.  So much for Pyracantha in my borders.

But, since I like the shrub and the Fall display it provides, I decided to place another specimen out on its own, farther from the house where an occasional pack rat colony wouldn't give me conniption fits and where the beauty of the shrub could romp unrestrained without danger to more refined perennials.  It sits now in my far front yard, sited so as to obscure the electric box and water meter from view of the house, in a manner recommended by any and all landscape manuals that the Extension service provides.  See, you can't see the electric box at all in the picture above.  Nor the pack rat colony growing at its base.  I did warn you, didn't I, that there are times when it looks ratty?

Just Cut It Out

I must admit there are times, even though I'm a plant fanatic first and a garden designer second (or, truthfully, last), that I am forced to see the folly of my ways and can even grow to hate a given plant. I don't often hate the plant for being a bad plant, mind, I usually just hate a specific specimen because of my own error of putting it in the wrong place or underestimating its ultimate size or for not providing the proper maintenance, or some combination of all of the above.

At such times, the longer I garden, the more willing I am to face facts and sever the apron strings; or in this case, the plant's stem.  Look if you will at the 'Josee' lilac (Syringa x 'Josee') in my front garden (arrows).  Now five years old, it has grown far bigger than the tag suggested, it obscures a window, and it is out of proportion with the rest of the front shrubs and perennials.  I tried cutting it back severely once, but a year later it is right back where we started; too big. To make my distaste for this plant worse, although I planted two of these beauties because they were the only reblooming lilac on the market (one in this bed and one in back of the house), neither has rebloomed well;  they do have a nice bloom in the spring towards the end of the period of the S. vulgaris hybrids, but then they have only a few sporadic small blooms over the summer and fall.  Now I could be partially to blame for that problem since the front bed of my house faces almost due north and so this particular lilac gets too much shade except in the summer, but the specimen I planted out back doesn't bloom any better and it gets southern exposure, full-day Kansas summer sun. 

So, on my list of things to get done this fall, I included banishing this lilac to a far bed on the property, perhaps never to be seen from again if it doesn't survive the move.  As you can see in the second picture, my front garden benefited tremendously from not having this behemoth squatting and pouting in the shade, and you can now see the house has a third nice window on that side.  And I'm happy, oh so happy, to be rid of that display of my horticultural ignorance. 

Sometimes I think I just need to let my surgeon side shine through more in the garden.  Amputation or excision is almost always the best first choice for treating a cancer and I know that, at least on a professional level.  Remove the tumor, cleanse the soul.
