Worst Weed Wednesday

It looks so harmless, the little yellow flowers, the foliage that could be mistaken for the benign clover or yellow wood sorrel. Don't be fooled. Black medic (Medicago lupulina) is a pernicious, nasty, thuggish weed. It can grow as an annual, biennial, or even as a perennial. I made the mistake of ignoring it while I concentrated on the even worse bindweed (which I eradicated). Now, I've lost the battle for the lawn on the south side of the driveway. It's almost entirely black medic now.
To eradicate it, the roots must be completely removed, which is quite a challenge as the roots break very easily. In addition to spreading by runners, it spreads by seeds, which turn black on ripening, for which is gets its common name.
I therefore choose black medic as the worst weed at Squirrelhaven. For other Worst Weed posts, visit Worst Weed Wednesday, brought to you by Dave of The Home Garden.

The Return of Foliage Friday

After I posted for Foliage Friday last week, I realized that I missed a lot of combinations, so here is a second post of foliage, including a couple of contrasting combinations, such as the Sedum 'Bertram Anderson,' Heuchera 'Citronelle,' and Ceratostigma plumbaginoides in the above photo. I like the way it looks now, but I planted this for autumn interest, when the Ceratostigma's blue flowers and red foliage will shine next to the Heuchera. This grouping in in partial shade.

Below is another grouping that will look even better in autumn, but provides interest in shade in the summer.
Clockwise from top left: Tree Peony, unknown Hosta, Actaea simplex 'James Compton,' Labrador Violets, same type of Hosta, Dicentra 'King of Hearts,' unknown Iris siberica, and in the middle Astrantia 'Moulin Rouge.'

Returning to the color echo theme of the last foliage post, and to one of the same plants,
here the red violet of the Painted Fern (Athyrium nipponicum 'Pictum') is echoed in the color of the Oxalis foliage. I'm so impressed with the performance of the Oxalis, which I'm trying for the first time this year, after falling in love with them in Austin last year at Spring Fling.

My favorite color for foliage combinations is chartreuse, and here are several examples.
Hosta 'Sweet Home Chicago' with Heucherella 'Sunspot'

Aquilegia vulgaris 'Leprechaun Gold' backed up by Hakeonechloa macra 'Aureola,' Violets, and Jack in the Pulpit (Arisamea triphyllum)

Below: the same mystery Hosta as above, with Aquilegia vulgaris 'Sunburst Ruby' and a Hellebore

Cotinus coggygria 'Ancot' (Golden Spirit) and Sedum 'Becka' (Autumn Delight)
The above photo and the next one are both full sun foliage combinations. Why should shade have all the fun?

If You Plant It, They Will Come

The Coneflowers (Echinacea purpurea) are in full bloom now, attracting all kinds of insects: honeybees and bumblebees,other bees and wasps,
and even Japanese Beetles (which are not welcome).
The first sighting of a Monarch butterfly in the garden this year was on the Coneflowers.They fill the front prairie planting and are scattered along the long border in partial shade in the back.
The Squirrelhaven Coneflowers are mostly seedlings from the local genotype and the cultivars 'Bright Star' and 'White Flower Farm Strain.' They exhibit much variation in size and color.
After days of observing pollinators at the Coneflowers, I've come to an interesting conclusion: all of them prefer the species-type to the hybrid dwarf Echinacea 'Emily Saul' (After Midnight) on the left, which I planted this year.
While not conclusive proof, the following video supports this conclusion by a preponderance of the evidence. (I apologize for the quality of the video; this is my first one. I filmed for 10 minutes and edited it.)

The events depicted are typical, and the time and day were chosen at random (it was overcast and the camera battery was charged).
I'm not suggesting that the fancy new hybrids shouldn't be planted. Instead, include a few Echinacea purpurea of the local genotype amongst those double, red, yellow, and dwarf Coneflowers. The pollinators will thank you.


(Edit. 7/24/09) I may have made the video too soon and rushed to judgement on inadequate evidence. Yesterday afternoon, I saw one bee visit the new flower on 'Emily Saul.' So it is probable that the existing flower was not fresh enough. However, it still appears that the bees favor the other Coneflowers more than 'Emily Saul,' as even when that bloom was fresh, I hadn't noticed bees visiting it. Draw your own conclusions.

Silly Redbud - Picture This Photo Contest

I took this photo in May at the library. I had no excuse to post it until Gardening Gone Wild announced flowering trees as the subject of this month's photo contest. One of the criteria the judge will be looking for is "[a]nything fun, novel, wacky or unexpected." These flowers blooming directly from the trunk seem to fit that description, for they made me giggle. I hope you find them as amusing.

Meme: The Best & Worst of This Year's Annuals

Recently, my mother-in -law commented that many of the annuals on her deck have fried in the heat and sun, and she asked me for recommendations for annuals that perform well all summer. This has inspired me to start a meme, seeking reviews of good and poor performing annuals. I hope you'll participate.

By this point in summer, it's obvious which annuals are a resounding success and which have gone down in flames. I'm going to start with the losers, the annuals that have caused me great angst and disappointment. I don't have a photo for loser #1 because there's nothing to show. That's right, all my Zinnias, those allegedly easy to grow annuals, failed to germinate. I haven't a single sorry seedling to show for my efforts. Second lamest are the Cosmos, which I sowed in the general vicinity of the Zinnias.Only a couple of them germinated, and they are sad, pathetic things. I had visions of clouds of pink Cosmos being feasted upon by hosts of butterflies. At this rate, I'll be lucky to have a single bloom by the end of August.
But enough of the washouts. Here are the best annuals this summer at Squirrelhaven. None of these great annuals are bothered by pests, and their foliage looks as good as the blooms. Sweet Alyssum (Lobularia maritima) always performs, every year, self-sowing around the prairie plants.Despite the lack of rain recently, it keeps plugging away, even along the driveway, without watering. I love this annual, which never needs gets deadheading.
Purchased as a small plant, this Angelonia angustifolia hybrid never fails to please.It also doesn't need deadheading, and blooms all summer. In full sun, it is more upright. It's paired with another of my favorite annuals, Osteospermum. Most Osteospermums take a break in the middle of summer, but this 'Soprano Purple' and the yellow 'Lemon Symphony' (seen below with a Coleus)keep right on blooming. They also don't need to be deadheaded, but they look the tidier for it.

Tops in the direct seeded category is the Black Peony Poppy that was the star of my Bloom Day post.The seeds were sown in March, and I was even able to move a few of the seedlings rather than just thinning them out.

What annuals have done well in your garden this summer, and which have failed spectacularly? Post about them and leave a link with Mr. Linky here. I'm curious about what's good and what to avoid.

Foliage Friday

Blackswamp Girl, at A Study in Contrasts, has come up with a great idea for a meme: showing off foliage combinations. Foliage is an essential part of any good garden, but it is crucial to a successful shade garden in the middle of summer. It was actually a challenge for me to find photos that depict only foliage without flowers. Here are my two. The above photo is a Painted Fern (Athyerium nipponicum 'Pictum') and the foliage of my favorite groundcover, Viola labradorica. In the background is Brunnera macrophylla 'Looking Glass.' The purple tones of the Violets pick up the purple of the fern, while the silver of the Brunnera matches the silver tones of the fern.
In this shot, the self-sow native Violet (Viola soraria) echoes the shape of the Hosta. Do you have any particularly successful foliage combinations?

Yes, There Actually are Things in Bloom in July

Larkspur (Consolida ambigua)

It's arguably the most popular meme in garden blogging, this 15th of the month floral extravaganza hosted by the inimitable Carol, of May Dreams Gardens, where a list of all the Garden Bloggers' Bloom Day posts may be found. Bloom Day is wonderful not just for getting inspiration from other gardeners, but also for comparing how one's own garden is faring. Last year was the perfect gardening year, so of course this year would suffer by comparison. Nevertheless, there are plants that failed to bloom this year, such as Heucheras 'Smoky Rose,' 'Lime Rickey' and 'Hollywood,' Astrantia 'Primadonna,' and Dicentra 'Candy Hearts' (which I believe is not "just resting"). The 90+F week without rain in June has caused the premature demise of blooms on several plants which were still in bloom last year on the 15th. And the unseasonable cool weather which followed the heat has delayed the blooming of other plants, such as Actaea racemosa. Even the Mophead Hydrangeas pale by comparison with last year, each with a single flowercluster. Welcome to normal.
Most of the photos in this post are of groups of plants, so that the entire habit of the plants can be seen. (Click on any photo to enlarge.) This is particularly apt in the following photo, which shows one of the most difficult microclimates in the home garden, the edge of the asphalt driveway in full sun.

But the plants growing here, the native grass Prairie Dropseed (Sporabolus heteroleptsis), the annual Sweet Alyssum, and the native Ruellia humilis just shrug off the heat that would fry more delicate plants (such as the Platycodon described by Beth Botts at Growing in Chicago). The Prairie Dropseed is in full flower, while the Phlox pilosa 'Eco Happy Traveler' (seen below with Little Bluestem) is on the way out.
The other native prairie plants are just coming into bloom now.
This bed is filled with Coneflowers (Echinacea purpurea) and Liatris, along with the non-native Allium sphaerocephalon. Just beyond them, not visible in the photo, is the native Allium cernuum, which was the subject of an excellent article in the current issue of Chicagoland Gardening Magazine written by Rose of Ramble On Rose.
It will start opening its pinkish-lavender flowers in a couple of days.

While I'm not wild about the pale pink color of this Aquilegia vulgaris, it's a keeper because of it's extremely long bloom time. It still has lots of buds, while the other Aquilegias have finished or are down to the last few blossoms.

July is the dullest month in the woodland garden, with the ephemerals starting to go dormant. The foliage of the native Celadine Poppy (Stylophorum diphyllum) is starting to tatter from the dryness, as we've had less than a half an inch of rain so far this month,
but the plants are still churning out the blooms, albeit more slowly than in May.

With fewer things blooming, I rely on Daylilies to provide interest, even in the shade. 'Chosen Love' has fewer blooms than it would have in full sun, but the blooms hold their color better.

There are a couple of native shade lovers that manage to bloom reliably without any direct sunlight and in fairly dry soil. The showiest is Actaea racemosa, also known as Black Cohosh.
(Does anyone know what a Cohosh is? I also have Blue Cohosh (Caulophyllum thalictroides), another woodland plant.) The Actaea is in bud and will have large, white flowers like pearls along the waving stalks. I have only the one plant, as I expected it to seed about. I must be pulling out the seedlings by mistake.
The other plant makes a good substitute for a shrub.
This Aralia racemosa (Spikenard) is 4 feet wide and tall, although in moister soils it gets even bigger. This is not a woody plant, and dies back to the ground in winter. While the flowers aren't very exciting, it has marvelous, wine colored berries.

Dicentra 'Bountiful' is looking the worse for wear, clearly in need of more water than its been getting. The dryness doesn't seem to bother its companion here, Campanula persicifolia 'Telham Beauty.'

Up by the patio, under the Crabapple tree, Hemerocallis 'Siloam Merle Kent' has just started blooming. It's supposed to have orchid pink blooms, but in the sun and heat, they all too often fade to peach by the afternoon.

The above view is from the patio towards the woodland garden. Clematis 'Betty Corning' is still blooming, although not as profusely as in June. The Japanese Beetles prefer this Clematis's flowers above all others in the garden. Against the opposite corner of the chimney are Clematis 'Rhapsody' and Hydrangea macrophylla 'Claudie,' which is in bud. 'Claudie' is a Lacecap Hydrangea for the North, blooming on new wood. I planted it last year, and after the winter it appeared to have given up the ghost. All the stems were dead, but then it sent up new growth. I was shocked to see buds on it. In the raised bed is Hemerocallis 'Druid's Chant' blooming for the first time, and
Campanula 'Samantha.' Next to the raised bed is my poor, beleaugured Oakleaf Hydrangea (Hydrangea quercifolia 'Snow Queen')
with Corydalis 'Blackberry Wine' at its feet, and Geranium 'Rozanne' climbing it.

On the arch (but not pictured), Clematises 'Evipo31' (Bonanza) and 'Madame Julia Correvon' have only a few blooms, while Clematis 'Comtesse de Bouchaud' (below) is doing her thing.
Beyond the arch is the Astilbe I think is 'Veronica Klose,' with Hydrangea macrophylla 'Penny Mac.' Hydrangea 'Bailmer' (Endless Summer) is over there too, and is virtually indisguishable from 'Penny Mac,' right down to having only one flowerhead. To the left of the Astilbe is the all white Astrantia 'Rainbow' (so named, one must assume, because white is made up of all the colors of the rainbow). The Alchemilla are on the way out, but still have a bit of color to them.

Some flowers are best appreciated in the closeup, and this is the case with my mystery Phlox maculata,
and the mystery dwarf Hosta.
It's probably 'Golden Tiara' from my mom's garden. I found the plant languishing under the Yew, so I moved it to the long border, where the best Heuchera and Campanula grow.

Heuchera 'Raspberry Ice' and Campanula 'Sarastro' bloom together all summer and into the fall. 'Sarastro' isn't blooming as profusely as in June, but it is ready for another major flush.

Next to Hosta 'Winfield Gold' (in bud), is a container I stuffed into the border to cover the gap between the spring bulbs and the summer flowers. I can't believe that after a week of temperatures in the 90sF, the Pansies and Wallflowers are still going strong. I just assumed I'd have to replace them by now.
The strange foliage coming out of the container belongs to the couple of Gladiolus callianthus (Acidanthera) that the squirrels missed.

Just in time for Bloom Day is my favorite Hemerocallis in the garden, 'Little Grapette.'
I prefer the small flowered Daylilies because they don't look like a terrible mess if deadheading is neglected for a day or two. I have 'Little Grapette' planted in several places, this one is next to its much larger relative Hemerocallis 'Pink Lavender Appeal,' by the completely unphotogenic tap.

In front of the southern fence, Hosta 'Maui Buttercups' is in full bloom. It needs something to back it up, but for now I've got seedling Lilies from Fairegarden planted there. (Thanks, Frances!) Against the fence, Clematis 'Silver Moon' is having a wonderful year, still loaded with blooms and even more buds.
On the other side of the Heptacodium miconiodes, Astilbe 'Visions' is finishing up.
The lavender flower in the background is a mystery single Poppy.

Skipping back to the long border, just beyond the container of Pansies and Wallflowers, Phlox paniculata 'Nicky' towers over Geranium 'Blogold' (Blue Sunrise), while Calycanthus floridus 'Athens' continues to churn out pale yellow, Juicy Fruit-scented blooms. (Thanks, Gail, for IDing the scent.)

Next to the Geranium, the lettuce 'Merlot' makes a stunning foliage accent for the Daylily 'Woodside Amethyst,' just opening in the morning sun.I moved the blue container with Osteospermum, Coleus, and Iris aureomarginata in front of the obelisk, as it was being obscured by the Calycanthus.

On the other side of the Daylily are an Aquilegia with its last blooms, and the last blooms of Penstemon from Fairegarden.

And now, the piece de resistance -
the Black Peony Poppy (Papaver paeoniflorum) (with Clematis 'Crystal Fountain' again in puff stage). Obviously, it's not really black, more of a very dark, grape soda purple. (For those with RHS color charts, the closest one is 79A with edges of 71A.) It's huge, it lasts for days, and I grew it from seed. This more than makes up for the disappointments of the Zinnias and the Cosmos.
What's blooming in your garden today?
