[notes on a vertical garden]

There are vines creeping up buildings and then there are vertical gardens. I came across this hotel in the middle of Rome around the hip Piazza Navona neighborhood. Its lush, plush presence amid densely-packed, stone, and plastered neighboring buildings and streets sated my inner Anne of Green Gables. Wisteria and Japanese Creeper (Boston Ivy) are planted on the roof, giving air + sun to roots + dramatic license to trailing vines. Note the gorgeous contrast of texture and shape of the potted palms + the deeply-inset Venetian Red windows (complementary colors).













...
which leads me to MFO Park by Raderschall Landscape Architects at a housing project close to where I used to live in Zurich, Switzerland. Yes, vines creeping up a building, yet inventively. Here an open steel structure with conical steel cable columns uses carefully-selected vines to make interior spaces, a grove, and a vegetated structure:

And finally to the Caixa Forum next to the Prado Museum and across the street from the Royal Botanical Garden in Madrid, Spain. While Herzog + de Meuron designed the building, Patrick Blanc--a vertical garden designer--designed the contrasting green wall. This project elevated the visibility of vertical gardens (aka: living walls, green walls) and they've been popping up in cities around the world. Two things you can't get from pictures: the smell + temperature of the space next to the wall. See design tips below for more info.

[design tips]

Vertical garden walls like Patrick Blanc's require an interlocking, waterproof, modular grid structure similar to those little plastic flats for plant starters or vertical columns with holes. Plant plugs are placed individually in each opening, increasingly without soil, and fed water + nutrients through an extensive internal irrigation system. 

TONS OF WATER required. In the absence of soil, they rely on potent mixes of fertilizers and compound nutrients, not making them a very environmentally-conscious design solution. While they are beautiful and do provide significant cooling properties to any building, beware "green-washing" lexicon around them. 

Vines, however, require less water (fewer plants) and have the capacity to grow in locations with less sun and available roof planting space. They also help to reduce the temperature of a building and its surrounding area. Vines work in a few ways: 
1. Twining (the entire vine twists around something)  
2. Tendrils (little arms shoot out from the stock to then twine)  
3. Adhesion (a disc with a natural chemical substance glues it to a surface)
Vines on buildings do require maintenance and must be systematically removed in order to not harm the structure on which they grow.

[notes from a roman palace]

It's easy to miss--this tiny, bark-covered woodland cottage in the heart of one of Rome's palaces. I walked right by it, looking instead for parterre gardens at the Palazzo Barberini: those ubiquitous geometric carpet-like gardens at European estates. Imagine: I walked right past the dwelling of bygone royal wood nymphs! Walls are covered, both inside and out with thick, spongy bark and intricate detailing of slender branches. Light filtered through foggy windows, and the world became still for a few moments. A good reminder to look between the mundane cracks of life for beautiful places + things.

[history of bark houses]
We all know the word wigwam but who knew what one looked like? 8'-10' wood-framed dwellings covered in birch bark, of varying lengths and shapes. Supposedly belonging to agricultural (vs. nomadic) Algonquian, Ojibway, and other tribes around the wooded Great Lakes region, these were some of the first recorded bark houses on the continent.

[design tips]
While building your own bark dwelling might not be possible, planting a grove of birch trees is within reach. At least that way you'll have free material when you are ready to start siding... Betula papyrifera or Paper or Canoe Birch is an excellent grove tree and one of my favorites in naturalized landscapes and urban wilds.



If you are inspired to side your urban garage or your wood nymph dwelling, I've discovered that bark shingle manufactures do exist. The typical overlapping shingle technique doesn't do the Barberini cottage justice, but it could be cobbled together without overlap with the same twig detail technique could be used to conceal seams. In terms of sustainability, it's often harvested today from Poplar and Chestnut trees and is incredibly durable, lasting for well over 50 years. See these two manufacturers:

Before signing off, a little eye candy of a third type of wood structures by one of my favorite artists, Patrick Dougherty, for a final moment of day-dreaming:

[notes from an umbrella grove]


400 stone steps down from the Vettica side of Praiano led me to a grove of Christo-Gates-orange beach umbrellas, sounds of dance music and rocks catching waves, and deep green pools where I spent sunup during the next week. In the absence of trees on this rocky cliff-lined coast, 50 para-sole carve a whimsical outdoor space suitable for a 40°C / 100°F summer day. 
 

The author's legs in the grove



With protection from the sun, water, a little garden, and chaises longues for sleeping, basic human needs were covered. Cold white wine, mojitos, tanned Italians, and dance music met other desires.





And then there's Claude Cormier's Sugar Beach project (brilliant) on Toronto's newly renovated waterfront. Another favorite umbrella grove, and an alternative to trees on a grassy lawn...
