The KAFM 88.1 Native Garden revisited, one year on.

January 2015


Weeds and rain runoff, 2015.

Now; September 2016
Young plants planted after June of last year have only been watered once this year- in July.  
Does the Zinnia grandiflora tone down that lovely fire hydrant, Susan?  

Admittedly, a few foreigners have snuck into 1304 Ute Avenue's "Native Garden." I did not expect he mediterranean Limonium minutum, or Dwarf Statice, to not only survive but bloom unirrigated. It's 3" tall.

Interesting pollinators have been attracted. This bee rests on Sideroxylon lanuginosum, Gum Bumelia or Chittamwood, a dry Texas tree which has done remarkably well in this trial.  

We are honing in on the grass swath treatment; it's not perfect yet.  But it sure beats boxwood hedge.

The idea of a hybrid Mongolian plant dead in heaps around a native is a little ironic in memory of some of the stories of Genghis Khan's activities with Jin China.

I get a certain diabolical pleasure from chopping up and mulching my natives with plants which are not as appropriate as they are.  Here, a trial California Manzanita (Arctostaphylos glauca) enjoys a cooling skirt of blue mist spirea carcasses.  (Caryopteris x clandonensis)  I'll confess that the blue mist is a great bee feeding plant with a great xeric constitution, but its so over-used and poorly designed with.

The most guiltless joy was Euonymous getting chipped.  Now I'm a proper sicko.

We are adding new plants to fill in, experiment, or replace the few weaklings who failed.  
Our new system is to flag new plants within an established landscape so we remember to water them.  The flag may as well double as one of the shade-cloth's stakes.  It's easy to forget when you don't water anywhere else.

A couple corners where we took time to remove the worst of perennial weeds (Bermudagrass and field bindweed) are finally clean, so they just got plugged to fill in with the grass- Alkali dropseed.  Sporobolus airoides.  

An experiment in progress, Mentzelia decapetala in bud right of the door.
Stay tuned.  The crevice garden was full of educational disaster!

"Grandma and the Corpseflower"

This March, an old pet plant of mine finally did its trick.

I've got a small corpseflower or voodoo lily, Amorphophallus konjac, which is sister to Amorphopahllus titanum, which is famously the world's largest flower.  Both put up a fine stink when they bloom.  Native to Borneo and Southeast Asia respectively, they are a clan of plants which attract flies for pollination. As a plant, they are giant corms (bulbs) which produce one massive leaf per year in the summer, and occasionally bloom in late winter with a single, stinking bloom, which is essentially built of of a wrinkly pike wrapped in a single wrinkly giant petal.  No wonder it inspired such perverted scientific names.

 There it stands today, in a ten gallon pot, towering over all the baby plants in the nursery.  And by its side is a youth of the king-daddy species, A. titanum, who is putting out a nice new leaf right now.

I've been growing the bulb, which is now the size of a volleyball, since 2011.  It unfurls its great leaf every summer outside and sleeps dry and quietly indoors in a bucket under my desk all winter. Until late last winter.

I sent an email invitation out literally a day or two before it opened for a spontaneous wine & cheese and nasty plant party, not really knowing what its schedule would be.  It turned out to be a very fun little party. A lot of plant friends, especially from the cactus club, and dogs came over.

There was indeed an elusive-to-describe but ever-present odour in the air which one would immediately notice coming in the door, and was capable of gagging a person who took a sniff within a foot of the flower itself.  Someone brought some stinky cheese which we enjoyed.

But my favourite story is from our friend Ada who surprised me by not only coming, but arrived at the door with two bottles of wine to celebrate an echo of family history, and needed her picture taken with the plant.

For she knew of a family photo from circa 1938 of her grandma Ina and her great-grandmother, in turn, who grew the flower.   A glass of wine to toast grandma, 2016!

A Gravel Soapbox

To those who aim to have a "natural looking" garden/landscape/xeriscape/native garden/rock garden or any garden with gravel.

Here is a massive trick.
A feather you must stick in your hat.
Ever go hiking?  Mama nature rarely uses gravel.  
But we do, it's a valid thing for us to use in gardens.
But ol' Mama nature, when she does, it's never screened perfectly like our manufactured gravel, eh?

(Image: in the desert near Whitewater, CO. Basaltic gravel on a red clay, and habitat of the threatened hookless cactus: Sclerocactus glaucus)

The following three pictures are a gravel-topdressed xeric garden before the plants go in, near a paver path for reference.
Pure 1/2 inch screened gravel is a good base-layer; easy to dig/weed/hoe/look at.
But as flat as flat as boring can be.
Now, throw two handfuls of 1 inch gravel. Very unevenly.  It's heaviest on the lower left and hardly on the upper part at all.  Note that within the scope of the photo, the density of this 1-inch-screen gravel varies from nearly solid to none at all. Note that well.
Lastly, throw in three, yes, literally three pieces of a larger stone yet- 1 1/2 inch gravel.
And you have a dynamic, gently uneven and more "realistic" surface.

You could (and I will) add one or two golfball or softball-sized rocks of the same material, embedded  somewhere in there. (Easily done by simply stepping on it)

I learned this in art school.  When you painted an underpainting- you know, a brownish wash before you even start the portrait- it would be a dire mistake to start with it perfectly even across the whole canvas surface.  Mr. McCoy, our instructor, would always repeat the mantra:  to avoid equality in your composition; "Equals cancel out! Equals cancel out!"

He pointed out that painting a face with equal eyes gave them a creepy, dead stare.  It's true.

Now, for pictures of the overall landscape before and after what my coworker has termed "accent gravel:"

Just 1/2" gravel.
Now with "accent" gravels.
(That's Zinnia grandiflora and Oenothera macrocarpa (maybe) 'Silver Blade' photo-bombing the image and distracting you by being in bloom in August without irrigation)

The plants will be the active subject of this "art piece," but it helps, it really helps, to start with a proper canvas.
At the University of Texas El Paso; 
they've been doing gravel and "rip-rap" in the Southwest longer than we have and know how to do it. (Christine Ten Eyke design)

(Found a match! It was only 247 miles away. Getting a good match is important.)

Because it's a garish clash when they don't match, above. Like a minor-second interval in music. Being close, but not quite: it's worse than being further away.  

Now, this idea is not new. In Crevice garden history, the old school Czech masters would insist that one must create his own gravel to match the stone which the garden was made of- by breaking the unused stones down with a hammer- like a religious and repentant homage to nature's erosion: 

But I'm a lazy American and found a way for heavy equipment and the US dollar to do it for me so I can fake it.  

After all, in light of nature's stunning subtlety and elegance, we're all faking it.

You could take it farther:  If you used a different boulder/stone than the type of gravel. Pieces or gravel of that boulder's stone could be mixed/spread/faded or just lightly applied to the surrounding gravel to integrate the two elements- gravel and big stones.
Like so.

There is even more you could do.

Let's go beyond flat gravel.

Good News and Bad news for Crevice Gardening in the Southeast. And Trains.

When we started a crevice garden at the J.C. Raulston Arboretum in Raleigh, North Carolina, (one f the finest botanic operations on the planet, ) we thought it might be the first crevice garden in the America's Southeast. Today I learned that it wasn't, which is very cool, but that the old one was shut down last year. Dang.

The crevice-wall used recycled concrete and stone in the Mediterranean house at the John A. Sibley Horticultural Center at Callaway Gardens near Columbus, Georgia.

Also, in the last year, I discovered that the APEX crevice garden was not, in fact, the co-largest public crevice garden on the planet. It is outweighed by the one at Bangsbo, Denmark, built by the Czech Master,  Zdeněk Zvolánek.

I am trying to channel his spirit and ingenuity this week as we build the newest addition in the expansion of the gardens of the Durango Botanical Society in Southwestern Colorado, USA.

View from the second-story balcony of the Durango Public Library; the garden straddles the intersection of the Library's sidewalk and the well-traveled river trail /commuter path.

The deer are checking our work by night.

This is a three-section twenty-plus ton Twilight Gneiss crevice garden, using a coarse sand and expanded shale "soil mix".  600 plus alpine plants (mostly from LaPorte Avenue Nursery) will find their young feet in it this weekend! Come to the workshop and lecture on Saturday (7pm at the Rec Center following 6:30 at the site) if you live nearby!
