Plants

Continuing the gardenblogger tradition of showing off our blooms on the 15th of the month, I present one of my favorite scenes in the garden: lacecap hydrangeas, astilbes and (in the upper right) an ‘Anthony Waterer’ spirea.  For a longer view, click on over to GardenRant.

They certainly require the most maintenance of all the plants I’ve ever grown, trying as I do to avoid high-maintenance plants altogether.  

Hardy Kiwi

But let me make my case.  On the left in this photo the bright green foliage is just a hint of the vigor to come from three hardy kiwis that I struggle to keep from eating my house. Over the course of the summer I’ll fill 8 to 10 full-size trash cans with the trimmings, and that’s a lot of trimming.  No wonder the standard advice is to prune it back HARD in early spring - which I don’t do because I’d have to retrain it to where I want it every year.  After eight years it began producing flowers, but so far, no fruits have appeared.  Yes, I supposedly have at least one male and one female - if tags are to be believed - so I still have hope after 12 years growing the stuff.   It’s the most commented-on plant in my garden, hands down.

English ivy 

And what’s that ugly brown stuff on the trellis but good old (ugh) English ivy, the ground cover/climber that blankets the land in large parts of my county, including the wooded valley my garden is part of.  Seeking to cover the crappy metal wall of my tool shed, the walls with the ever-peeling paint no matter how what type is used, I added a trellis and trained some of my existing ivy up it.  You know how mistakes can look fine the first season and bite your ass the second?  That’s the story of this mistake, and now the vines have covered the window and are quickly covering the roof, too, and there’s no way to trim it coz it’s out of reach.

So last fall I removed what I could reach and just let the unreachable parts die over the winter - but LOOK at it!  Now I’ll be seeing those dead leaves all season, at least.  When I did the same cut-and-let-die trick on the ivy covering my trees it took at least a year for the stuff to fall off.  Though finally there was a pay-off when birds made good use of the dead stems for their nests.  So, a happy ending, I guess. 

Crossvine/bignonia

Now look above the tool shed over to my neighbors’ trellis and you see a vine I’ve been coveting for its huge orange tubular flowers, its green leaves all winter, and the fact that it’s native.  (It’s always nice to find another native that does well in the garden to add to the great sustainable nonnatives I’ve collected over the decades.)  I’ve already bought one, in fact, and it’s now at the base of the trellis, getting settled in its new home.  But I’m leery of even this seemingly perfect vine.  Will it, too, become a headache, a chore, an unruly mess?  You know, like the trumpet vine I just bought - also a native - is predicted to become?

But enough of my plant rant.  What’s YOUR most demanding plant or plant group?

It’s a glorious mid-spring day here in Maryland, perfect for the Open Garden and Plant Giveway I’m throwing for my coaching clients.  This is the first of its kind, though,  I’m not sure why because my garden yields lots of passalongs every year and who better to give them to?  Also this year I’ve started sending clients seasonal to-do lists with links to full instructions.  Rather than write up names and instructions, I’m sending everyone to this page to find out what they have and how to keep it alive. 

Your new plants

• New England asters are native to this area and love the sun.  
• Celandine poppies are native to this area.  They only bloom once - now - but the foliage looks fabulous all season.  They’re shade-lovers that’ll seed vigorously for you.
• Solomon’s seal  do bloom but are primarily grown for their green and white foliage - though they’ll disappear completely after the first hard frost.  Their tuber-like roots spread and make this plant quite drought-tolerant, but those tall stalks may flop after you’ve planted them.  If so, you could cut back the stems by half or even stake the stems til the roots are settled enough to hold them up.
• Astilbes like shade or part-shade (preferably not hot afternoon sun).
• Euphorbia amygdaloides var. robbiae (Robb’s Spurge) is what I have the most of.  I’ve trimmed off the chartreuse flowers on the giveaways because otherwise, they’d flop (not liking being moved in flower).  These evergreen beauties can’t tolerate any hot sun directly on them.   They spread by those long tendril-type roots.
• The assorted hostas have to go because I now have deer.   Except for a couple of short green and white ones, they’re all large cultivars, blue or chartreuse.
• Sedum ‘Autumn Joy’ are 15" tall, love sun and attract swarms of pollinators.  Their cauliflower-like flowers start creamy in late summer, then turn pink, red and rust in succession.  You can leave the dried flowers up all winter for "winter interest," but cut off the dead ones in early spring. 

How to keep them alive
Get them in the ground as soon as possible, with good soil-root contact (pat them down) and give ‘em a good soaking.  Then keep the soil around them wet for a week - longer if they’re in the hot sun (and you might even construct some temporary shade for them.)  Then keep an eye on them for the first month in their new home.  Especially when the temperatures are near or approaching 90, like now, transplants are in danger of not surviving the move.  Water, water, water.

For as long as anyone can remember, the wooded valley that my back yard is part of has been covered with English ivy.  Not just on the forest floor but even up into the trees where it matures and produces berries, berries that are then spread far and wide by the birds.  But then came another vine that - can it be? - managed to win the battle of primacy with the ivy - the five-leaf akebia.  It now has a lock on the lowest, wettest parts of the valley.

Then suddenly the fastest spreading invasive plant EVER landed in our valley -  the lovely garlic mustard.  Its beauty (of sorts) is important to mention because when I’ve shown it to neighbors I’ve discovered that it’s been picked, brought indoors and admired!   Oh well.  Even if they removed it by its roots it wouldn’t slow the steady march of garlic mustard across the woodland floor.  

It’s really no wonder this plant is so successful.  It likes the sun, it likes the shade, it seems to like every damn location in North America. 

So thank to Barbara Lucas and her pals in the Midwest for this video that goes a long way to showing exactly what mustard garlic looks like and then how to get rid of it.  I think I’ll forward this to my neighborhood Yahoo group with the broad hint that we make ridding our valley of this one plant our New Year’s Resolution for the lovely woodland we share.

Thanks to Janet Draper, horticulturist at the Smithsonian’s Ripley Garden on the National Mall, I’m CRAVING these flowering annuals, all super-easy to grow from seed outdoors.  Yes, I was much relieved to hear Janet dismiss the notion of growing seed indoors as waaay too much trouble.  I hear ya!  But these beauties can be just tossed about for that wild, cottage-garden look - once, and you never have to buy them again.  Then to "design" them, just edit out the ones you don’t want.  Oh, and the tossing about can start now, in late winter as the snows melt.  

Upper left are Sweet Asyllum (Lobularia maritima) in rose pink.

Upper right the very cool seeds pods of Opium Poppy (Papaver somniferum).  Gotta have it.

Lower right - nice mix of Forget-Me-Nots (Myosostis)

Lower left, gorgeous mix of larkspur, lillies, achillea, and echinops.

Drama doesn’t have to stop by Thanksgiving if you know how to pack a pot as gorgeous as this one.  It stopped me in my tracks the other day, rushing to hear teacher/writer Rick Darke speak at the National Arboretum.

But because I don’t know what plants these are and discerning readers want plant names, damn it, I’ll shoot this link to someone at the Arb for a quick plant ID.

UPDATE:  National Arb horticulturist Scott Aker writes to tell me these plants are "Furcraea foetida ‘Mediopicta’ and Kalanchoe thyrsifolia, I believe."

Notice the fudge factor there, the "I believe"?

In observance of Garden Blogger Bloom Day*, I present the most photogenic spot in my garden, and it’s that most public of them all - the curb garden.  This combination of beautyberrry and Sedum ‘Autumn Joy’ just blows me away.  Here’s a close-up.

• Sedum
• Beautyberry (Callicarpa)
• Miscanthus sinensus ‘Morning Light’
  
• Caryopteris
• Hardy begonia
• Japanese anemone 
• Aster
• Blush ‘Knockout’ rose, photo below.

And just how sustainable are they?

Here’s what resources it takes to keep these plants alive and looking good. 

• Sedum and Miscanthus are super-drought-tolerant and require no care except for chopping them down in early spring.  Also, the sedum needs to be divided every three years or so or it’ll flop.

• Caryopteris, hardy begonia, Japanese anemone and asters are of average to good drought-tolerance and get no care from me except for their yearly pruning.  Only problem is with the asters, which have looked awfully crappy for two years running now.  Last year I thought the culprit was drought but this year, with plenty of rain, I just don’t get it.  Some undiagnosed disease?  (Here’s a post and photo - any ideas?)

• 

  Knockout roses, also of average drought tolerance, are disease-resistant enough to still have great-looking foliage now in October, so they’re FAR more sustainable than most roses.   They also don’t require deadheading.  As for fertilizer, in their first year in my garden they bloomed heavily until December with no fertilizer at all from yours truly, though I’m experimenting with a dose of Rosetone a couple times a year to see if it makes a difference.. 

*Why a day early?  Coz tomorrow is Blog Action Day!

Behold my dreaded underdeck area, with its patch of liriope and lots of English ivy.  The idea was to just not let the ivy spread onto the adjoining mixed border.  You know, keep an eye on it.  How delusional was I?  

Finally an irrefutable truth in gardening struck me - that ivy cannot be trusted in proximity to other plants, mere shrubs, perennials and other groundcovers, which let’s face it, never had a chance compared to this super-thug. 

And coincidental to this realization was the arrival of a visitor to my garden, a serious gardener, who suggested that in full shade surely even creeping liriope would be better behaved than the dreaded English ivy.  Apparently Ketzel has lived in the Pacific Northwest long enough now to have acquired a visceral hatred of English ivy, seeing as how it’s destroyed so much of their forest and gone and gotten itself outlawed, for crissakes.

Light goes on!  Rip out the damn ivy and replace it with NOT plain old liriope but the far lovelier carex varieties I have plenty extras of - full grown, free.  All it takes is removing the ivy patch from under the deck stairwell.  You know how the site prep turns out to be a MUCH bigger deal than the planting, right?  Ah, but the imagined bareness of a new palette for my design fancies carried me through four days of ivy removal from this spot and another area of the same size adjoining it.  Some of the ivy has been there for 30 or more years, by the way, so removing it was no picnic.  In all, I removed 10 trashcans-full of the stuff.  Good riddance! 

And here’s the simple "after" of an all-evergreen mix of large plain Carex and smaller variegated ‘Ice Dance’ Carex, which I-swear-to-God look just like this even in January in sheltered spot like this one.  As a garnish I’ve planted some hardy begonia and sweet woodruff in there, too.   Then a layer of mulch and MAN, it looks nice to me.

So why is it we come to hate certain plants SO MUCH?  It used to be I just hated English ivy when I saw it growing into trees but now I’m just sick-sick-sick of its endless, vigorous march onward to conquer every plant and building on my property.  I want it GONE. 

So are there any plants that YOU hate at a visceral level?

You can tell us.

 In the fine tradition of gardenblogging, I present a snapshot of what’s flowering in my garden at mid-month.  Doing a grassy version of flowering is this Miscanthus sinensus but don’t worry; this late-flowering variety - ‘Morning Light’ -  isn’t invasive.   (Here’s more about that.)  This one does a great job hiding my trash cans.

More blooming action in my garden?

• ‘Flower Carpet’ rose
  
• Caryopteris
• Hardy begonia
• Japanese anemone
• Spirea reblooming 
• Lespedeza
• Aster
• Salvia
• Sedum in pots - photo on GardenRant.
