Visit this park

Grand Park, Los Angeles. Photo credit: Pure Wow.

There are few public spaces we have been to in recent years that have left such an impression on us as Grand Park in Los Angeles. We knew the space when it was eyesore parking lot and drab civic plaza halfheartedly connecting City Hall to the Music Center on Bunker Hill. If these spaces of yore symbolized anything about the city and its vision, they symbolized a city with little vision. The new incarnation of these spaces, however, signals a true step forward, and a look ahead.

The park’s design is confident and playful, with a color and plant palette that tells the story of Los Angeles circa now, not circa 1855. It contains a combination of bold, plant-heavy spaces filled with groovy future-forward plants (re: waterwise but not drab); swaths of lawn for seating, lounging and gathering; simple architectural structures that sit perfectly within the space; hot pink tables and chairs that are both movable and serve as eye-catching sculpture dotting the space; and interpretive signs that tell the story of both the plants one finds in the space and their provenance.

Above all what is so refreshing about this park is its confidence and what that confidence says about an emerging new city. This is a city that tried (and has tried) for so long to pretend it was something it wasn’t, that it was a sleepy town or one large suburb, or that it was 24-7 New York, that it was tropical, rainsoaked Hawaii, or that it was just one huge disposable movie set. Grand Park in all its confidence and quirkiness seems to say, This is Los Angeles, and Los Angeles is wacky, and weird, and endlessly multifaceted, and that is what makes it both singular and lovable. For more info, check out Rios Clementi Hale (the studio responsible for the design and site planning), and Grand Park LA.

Plant provenance reveals much

Success with a plant is inextricably linked to knowledge of that plant’s provenance. If you know what the conditions of plant in its native habitat are, you will have a good gauge of whether or not you have or can effectively create the right growing conditions for it in your own landscape. Beth Chatto is perhaps the pioneer of this approach, of using plants whose natural growing conditions match the growing conditions of your site. And on the surface this sounds like such old news and so completely obvious that why should we care? Because more often than not information on the specific provenance of a plant and the particular climactic, geological, and topographic conditions of that place of origin are not immediately available. Rather, we are given a generic set of guidelines by which to care for the plant: average water needs, keep evenly moist, plant in fertile soil, fertilize annually.

We take the various Eremurus / foxtail lily species as a case in point. Some entries may make vague reference to the plants being from places such as Iran, Afghanistan, and the Hindu Kush, but the buck generally stops here. Without any information on their native growing conditions, we are then offered up generic advice on care of these plants, particularly with regards to water. In the case of Eremurus bungei, this site says that the soil should never be allowed to dry out once they are planted. This one doesn’t mention water at all. And this says “Average Water Needs; Water regularly; do not overwater”. We are left with the impression that Eremurus bungei / foxtail lily must be from an environment that is neither too wet nor too dry and that is never affected by drought. And none could be further from the truth. Their native growing conditions are intensely dry, including in winter (which are somewhat cold), and rocky. The plants shoot out leaves during the brief time when moisture is available in the soil and must gather up enough energy as quickly as possible before the heat and drought of summer set in and they go dormant once again. In short they are the prototypical dry-landscape/high-desert bulb.

This is not common knowledge in part because nurseries are thinking about sales and would like to sell more Eremurus than fewer, and thus if they are advertised as needing average this and average that, then the average person in average anyplace USA can purchase and grow them, regardless of whether this is true or not (and, yes, it is somewhat true: you can prep your soil in various ways to make certain species of Eremurus grow in Minneapolis or North Dakota, albeit a bit tenuously). The other reason for the lack of information on native growing conditions of landscape plants is that species plants (as opposed to cultivars) are relatively new to the gardening scene. Heretofore the provenance of most plants was the nursery, end of story. And many plants have been in cultivation for so long that common knowledge of their origins has all but disappeared (did anyone know, for example, that geraniums are actually native to very dry regions in South Africa?).

We have nothing against cultivars at all and use them when need be, but our hope is that as interest in species plants grows, so too will access to detailed information on these species plants’ native growing conditions. The result can not only be increased knowledge of and interest in protecting the native habitats of these plants, but also in more sophisticated, climate-specific plant palettes that truly mesh with the ebbs and flows of the places they are located in.

The irrigation-free landscape in the news

KSTP Channel 5 just produced a great piece on the irrigation-free landscape. Happy viewing, everyone.

Second hottest July on record, irrigation-free landscape thriving

We’ve held off on prematurely declaring the irrigation-free landscape a success, but thus far it has exceeded even our expectations. This July was the second hottest on record for Minneapolis, with June being particularly sweltering too. In spite of this, of the 204 plants in the irrigation-free landscape, 90% of them have not been watered since June 6. And they are thriving. A recent visitor to the landscape commented the landscape looks so full you would have no idea it was only planted less than two months ago and that most of the plants haven’t had supplemental water since early June. For more photos of how the landscape has evolved and grown, click here. Seeing is believing, though, so come by for a visit: 2853 42nd Avenue South, Minneapolis, MN.

Helen Mirren on plants and gardening

Tags: , , , ,

What we love about this clip – aside from the simple fact that it is the lovely and articulate Helen Mirren just being herself – is what she says about the pleasures of being a part of a communal garden and the gardening camaraderie she enjoys there. This is something the American gardening world so often sorely lacks, as it seems we are obsessed with competition and purism and exclusivity, all at the expense of sharing and learning and creating a genuine community of gardeners, and a growing, evolving body of dogma-free knowledge.
