landscaping horror: where diy meets wtf

15 Comments

One of my friends recently turned me on to Regretsy, a blog that gathers together some of the more unfortunate objects that earnest DIYers have made and posted for sale at the Etsy craft site.

I really like Regretsy’s tag line, “where DIY meets WTF,” and I’ve borrowed it for the subtitle of this quick post on a new garden space that went up in my neighborhood, a bit of landscaping horribleness that seemed perfect for Halloween.

I thank John for noticing it first and pointing it out to me, knowing how well I’d appreciate it. “It’s on the right as you head down the hill. You can’t miss it.”

Ah, what a wonder: plastic grass-colored indoor-outdoor carpeting, one of my personal favs…placed naturalistically between the sidewalk and the side fence…

But it gets better! Ever six feet or so, next to the fence, the designer has planted big red silk roses. I’m sure they were meant to coordinate with the red curb.

A garden made out of dead things emulating live ones. Zombies. Plastic roses. Be afraid. Be very afraid.

One of the dangers of having lovely flowers next to a public walkway is that someone might want to pick them.

One of the roses planted in this plastic lawn. Note the price tag still attached.

Could this be the latest avant-garde garden designed by Martha Schwartz, who’s incorporated plastic plants into her designs, as in her [ Splice Garden, at Cambridge’s Whitehead Institute ]?

No, sadly, probably not. But I will force myself to say something nice about it: At least it doesn’t require watering, except maybe to hose off the dust.

stefano mancuso, standing up for plants

Plants are way smarter than humans give them credit for being…

Here’s a cool, thoughtful video from the very cool TED program that I was first pointed out to me courtesy of a link sent out by International Carnivorous Plant Society. (Yes, there are a couple shots of a Venus flytrap.)

You can select subtitling into any of ten languages in case you’d like to catch every word Stefano Mancuso, one of the founders of plant neurobiology, has to say. Part of his message: Genesis got it all wrong, but then so did Aristotle.

(An aside: I’ve written at least once about pronouncing scientific Latin names. Listen to how Mancuso pronounces the Latin name of California’s own giant sequoia, Sequoiadendron giganteum at the 3:51 mark. If there’s any country that can lay claim to even begin to pronounce Latin correctly it’s gotta be Italy, and the way the name comes out sounding has almost nothing to do with how I’m used to hearing it. Of course the word “Sequoia” originates on this side of the pond, so this is a puzzle with no real answer–the most interesting kind!)

unusual october

5 Comments

October usually throws some ridiculously warm and dry weather at us. This was the month that in 2003 and 2007 saw monster wildfires racing through the county, including the largest fire to hit California in recorded history (in 2003).

We’ve a few of those warmer days, but what’s been surprising has the the cool, wet foretaste of winter. Here’s a little example: This is my parking pass for work, where I usually go in to the office Mondays through Thursdays. Each big dark X corresponds to a day when it was too wet to ride my scooter in to work. Add to that another morning when I got a bad weather report and arrived pretty drenched.

Over the last two weeks it seems like half the mornings looked a little like this, with mist–or outright rain–turning the pavement wet.

Finally, the line of repurposed cat litter buckets that had looked so forlorn all summer at the drip edges of the roof were beginning to fill with water. In fact my two rain big barrels are now full, ready to have their contents shared back into the garden.

In response to the cooling trend plants are leafing out; seedlings are germinating. Readers not in mediterranean climates might think they’re reading a garden blog from the southern hemisphere. But no, this is California, which shares this wet-winter/dry-summer climate with less than 5% of the earth’s surface. To make up for being so special we’re treated with almost 20% of all the world’s plant species. More than a fair trade for long summer months with close to no water.

I was out in the front yard over the weekend, tidying up growth that had hit its expiration date. Mixed in with branches that had truly died were plenty belonging to drought-deciduous plants that were coming back to life. On the left is our local chaparral currant, Ribes indecorum, turning from brown twigs to leafy twigs. On the right is Verbena lilacina, a plant that can stay looking fairly green over the summer if you give it more water than I do.

Everywhere I stepped I had to avoid mashing tiny little buckwheat seedlings, or these guys, itty bitty little chia plants (Salvia columbariae). Early this summer when I took out the dead plants of this annual I made a point of shaking the seed heads over the dirt. Still I was worried that I wouldn’t have enough germination to repeat the amazing show of last spring. Looks like I didn’t need to be so concerned.

In the back yard seedlings of baby blue eyes were pushing their way through the mulch. The mulch really does help keep down the weeds, but this species fortunately doesn’t seem overly daunted by my attempt to save myself a few dozen hours of weeding. Various creatures do find these seedlings extra-tasty–including the cat, which seems to think these are almost as good as catnip. Once they’re larger the cat doesn’t seem to pay them any attention. I’m hoping for a nice half dozen or so survivors.

And there were even more seedlings. These are a few days away from showing their first true leaves, but I’m hoping that they’re the beginnings of clarkias that surrounded this patch of bare dirt. If not clarkias, they’re likely seedlings of this really noxious weed that shared the space with the clarkias. We’ll soon find out…

Yes, it’s been an unusual October. But I’ll take plants leafing out and seedlings pushing their way out of the ground any day over another round of brushfires!

my new natives

15 Comments

Saturday was my local California Native Plant Society’s annual plant sale.

Eight hours on my feet, volunteering, had me pretty exhausted, but not too exhausted to shop! Still, I thought Saturday’s haul showed remarkable focus and restraint–except for one plant.

I’ve threatened to start a collection of dudleyas, that cool mostly-California genus of rosette-forming succulents. I have several species in the garden already, and I’ve always been struck by the subtle variations between the different kinds. I think that you can make out some of the differences pretty easily in the big group photo above, though a couple are immature plants and will look a little more like their relatives when grown up.

So here are the new additions:

Dudleya abramsii, Abrams’ dudleya.

Orcutt’s dudleya, D. attenuata ssp. orcuttii.

Britton’s dudleya, D. brittonii, a Baja species, probably one of the biggest, splashiest of this genus.

Candle holder live-forever, D. candelabrum, another of the larger, more charismatic species. This hails from the Channel Islands off Santa Barbara.

Bright green dudleya, D. virens ssp. hassei (also called D. hassei). The “bright green” in this Catalina Island species appears to be a misnomer since my plant looks really white or blue-green, as do the photos up on CalPhotos.

Sticky dudleya, D. viscida, a plant only found in the low southern end of the state.

Looking at the first photo you’ll probably notice a plant that looks nothing like a dudleya. That plant is thick-leaved yerba santa, Eriodichtyon crassifolium. With a reputation for spreading when it’s happy, this isn’t a plant for every garden. There’s a spot behind the back fence on the slope garden where there’s a tangle of iceplant and ivy. If any plant stands a chance against those two nemeses it might be this one. I’ve loved its lavender flowers in the spring and the strikingly modern upright growth habit. It’ll give me more excuses to tend this little wasteland of a garden space, my little secret garden with big, scary datura flowers and the even scarier iceplant and ivy.

Here’s a quick roundup of what’s blooming in the October garden. It might look like a lot, but this is probably 90% of everything that has anything looking remotely like a flower on it, and a lot of these are tiny tiny flowers on big big plants that are grown primarily for their foliage and structure. It makes you a little more appreciative of the plants that make this hard time of year their floral niche.

Just starting up their bloom are the first of the paperwhite narcissus, Camellia sasanqua ‘Cleopatra,’ Stapelia gettleffii and Protea Pink Ice.

Salvia clevelandii ‘Winnifred Gilman’ is showing a second burst of energy, blooming not quite as intensely as in the spring, but with more vigor than over the summer.

All the rest of the plants have been blooming for a few months now, and a few of those fall into the almost-everblooming category–plants forever thinking about S. E. X. Click any of the little thumbnails below for a closer look, or hover over the thumbnail for the plant name. (And my apologies for a few repeats of some of the same images above–My gallery software only has an all-or-nothing option for posting these.)

Thanks to Carol at May Dreams Gardens for hosting this monthly roundup (even though it’s actually been a few months since I posted…). Check out this month’s other [ Garden Bloggers’ Bloom Day posts ]

seed bomb controversies

13 Comments

Someone has declared tomorrow, October 9, 2010 as International Tulip Guerrilla Gardening Day. [ Here’s the Facebook event. ] I won’t be discussing tulips, but this post does have a few things to say about guerrilla gardening.

The local native plant listserv lit up a few weeks ago over a story in the local paper about seed bombs that ran on August 30.

If you’re not up on seed bombs here’s a little background: The idea of rolling up seeds and clay to make little balls that could be lobbed into an area to sow the seeds probably goes back centuries. But the technique was revitalized in Japan by Masanobu Fukuoka during the last century as part of a low-disturbance style of planting. Instead of tilling the ground, these lumps of seed and clay could be spread out on the earth’s surface, reducing ground disturbance and the resulting need to weed so intensely. Up to that point the little round seed delivery devices were known as seed balls, earth balls or even clay dumplings.

With the rise of the militant guerrilla gardening movement, the little seed ball became one of the weapons of choice against what was perceived as urban blight. An untended vacant lot could be showered with with these little projectiles, and a few good rains could see the seeds sprouting and taking over what might have been invasive weeds. In the testosterone-soaked guerrilla garden movement the friendly seed ball quickly became rebranded a “seed bomb.”

Now we return to current times and the article I started out mentioning: The original cut of the article touted how these particular seed bombs contained native species, including–cue the scary music–sweet alyssum! While the definitely-not-native sweet alyssum isn’t one of the top two or three most invasive plants, it’s undisputedly a problem and has no business in a seed ball that could get hurled into an wild area by a well-meaning guerrilla gardener. In my own garden, a sowing of the stuff twenty years ago has led to a situation of seedlings still popping up every time it rains.

The article generated all sorts of comments, and several people wrote directly to the maker of these particular seed bombs mentioned in the paper, Jim Mumford of GreenScaped Buildings. One thing led to another and it was revealed that the newspaper got hold of a bad list of ingredients, and that sweet alyssum had never been a part of the mix. The newspaper ran a sidebar correction to the story. (The species used to me looks like the California native wildflower mix offered by S&S Seeds.)

Still by that point the damage had been done, and the creator of these particular balls felt like he needed to show up last month at the lion’s den of the the native plant society meeting to do some damage control. He brought us all a big bag of free seed balls. He ran down the real list of species that were really in the mix. He reiterated that sweet alyssum had never been part of the mix.

When it was all over, several in the audience were saying they had no trouble with the species used to make the seed balls. The plants were all from California and weren’t considered invasive. But this was a tough crowd to please and there were still a few lingering concerns.

Within the state there are distinct forms of many of the plants in the mix, and each region’s flora has a particular balance of local plants. If you bring in a non-local strain of a “native” plant you might do something to mess up that balance. Really the only way to make a safe seed bomb that you might lob into a wild area would be to use seed from local plants. Seed bombs are fun, but keep them confined to urban gardens away from wildlands and don’t go tossing the balls into your neighborhood canyon thinking you’re doing the earth a favor.

The story of the San Diego seed bombs has a relatively happy ending. But over the last couple of months I’ve run across a seller who offers “West Coast seed bombs” on Etsy and through a number of boutiques. The vendor lists the ingredients as “Cornflower, Siberian Wallflower, Garland Chrysanthemum, Shasta Daisy, Farewell-to-Spring, Plains Coreopsis, Sulphur Cosmos, Wild Cosmos, African Daisy, Sweet William, California Poppy, Blanket Flower, Baby’s Breath, Tidy Tips, Mountain Phlox, Blue Flax, Sweet Alyssum, Annual Lupine, Lemon Mint, Red Poppy, Rocky Mountain Penstemon, Desert Bluebell, Mexican Hat, Gloriosa Daisy, None-so-Pretty, Prairie Coneflower, and Black-eyed Susan.” Not only does this mix include sweet alyssum, it contains garland chrysanthemum, one of our local scourges. Some parts of the country also have problems with the baby’s breath.

The issue of invasives aside, it makes me wonder about people’s definitions of what constitutes a wildflower. Siberian wallflower on the West Coast? African daisy?

I got in touch with the makers of these seed bombs, and they were quite responsive, saying “we are continually developing this product. Your feedback will help inform our product going forward and is much appreciated. We will gladly include information about the danger of invasive species in our product from here forward.” And they asked for suggestions for plants that would be better citizens in a West Coast wildflower mix. Off the top of my head I referred them to the list accompanying the article, and added just a few ideas of California natives not on the list: baby blue eyes, fivespot, coast sunflower, desert marigold. What others would you recommend?

If the makers of these seed balls drastically change their mix we could have another relatively happy ending. Most of us probably have non-native plants in our gardens. If what happens in the garden stays in the garden, then it’s not quite a doom and gloom scenario. But we definitely have a problem if people start throwing seed bombs into the wilds.

In this case, accompanying the seed balls with a note about the potential threat of invasive plants could do as much good as reformulating the mix.
