Make Space: Installation/Open House at La Reunion TX 2010


Brad Ford Smith
It was a beautiful blue sky, puffy cloud day, perfect for the Make Space: installation event at La Reunion TX. I got up there early to do a few finishing bits to my sculpture and clean up around the site. Then I spent the rest of the day talking to people, petting dogs, and enjoying the sun shine.

Below are photos of some of the sculptures made by the other artists for this years event. If the names are high lighted they link to the artist's web site.

Unfortunately I did not get a photo of Sandra Groomer's installation, but there should be some posted at the La Reunion TX site soon.

Privet Sculpture Project Construction Day 3





All the arches are in place, 12 in all, spanning 40 feet. Sadly, the photographs really don't capture it very well at all.

I'll be out there early on Saturday, Open House 2-4 to add a few elements around the main arch.

These are the flying buttresses that were added for stability. The privet when freshly cut is very bendable. Only a few branches broke during construction. As the wood dries is becomes harder and more apt to brake and split. Over all the structure is very stable. I am expecting the wood to weather very well over it's year long existence. The bailing wire might be an issue with rust, so I'll beef that up on Saturday.

Privet Sculpture Project Construction Day 2


Despite the cold and rain, things are progressing. 4 1/2 of the 7 arches are in place. They need to be tweaked and fattened up a bit. I am also adding some side arches at the gate opening for stability.

The bundles are tied together with bailing wire, which was donated to the project by Susan Giller, an artist that is known to create strange bunny people with wire.

Privet does not have stickers in the normal definition of the word. What it has are numerous pointy bits along the branches that are the stubs of old dead twigs. These twigs can be very sharp.

At the End of the First Day of Construction on the Privet Sculpture Project

At the end of the first day of construction I learned that not all privet can be used the same. If the branch has any elbows it won't bend smoothly. The long shoots that grow straight up in one season are ideal for the ridged bundled arches that the PSP requires.

First Stake in the Ground for the Privet Sculpture Project

The structure will be staked to the ground using thick privet branches. It will be interesting to see what condition they are in after a year in the dirt. The dirt at this location is on about 10" deep then you hit lime stone, which is the reason this area is called Chalk Hill. The photo also shows some of the long privet branches that have been harvested to create the arched structure.

Location for the Privet Sculpture Project

The opening for Make Space: Installation at La Reunion TX is this Saturday, Feb. 27th. With all the rain and snow it has been hard for any of the artists to get out there, but I do have my sculpture sited now, and I have started the framing out of the structure. Above is the concept drawing superimposed at the site.

There has been some interesting issues around using privet as a building material, I'll blog about that later. Right now I need to get into my muddy boots and rain coat, pack up the truck and head out to La Reunion TX.

Privet, Basic Structure and Seed Distribution


The structure and seed zones of privet

Privet growing in the wild sends out branches from a central root ball. It has corresponding small branches that sprout along the main branch. As the main branch grows longer it bends, making an arch. The small branches on the top of the arch grow towards the sun light while the branches on the underside dry up and snap off, leaving rows of small stubs. These stubs are reinforced over the seasons to form a thorn like defense. This pattern of the branch arching, growing and branching out repeats every season resulting in the main branch becoming a series of arches that can extend over 10 feet in length (as observed at La Reunion TX).

With each season, new branches sprout from the root ball and grow straight up, using the older branches as support. Once they have cleared the leafy privet canapé, the small side branches begin. The seeds and new leaves will only form on new growth. The long clusters of hard round seeds tend to be located on the farthest tips of the branches where they can be seen by animals and whipped about in the wind.

Cutting a branch usually results in a growth spurt around the stump and along the branch. Cutting a branch at the base of the plant tends to multiple the amount of new branches sprouting up from the root ball.

New sprouting seeds

Cutting all the branches down to the base allows sun light to reach the unsprouted seeds, this combined with a little rain water will activate all the seeds.

Spreading the Seed

Frass, Droppings, Spore, Poop... What ever you call it, this is a big stinking pile of privet seeds.

One privet bush can produce thousands of seeds every year. These hard round black seeds have a multitude of ways of finding fertile ground. First is the structural nature of the bush itself. It grows in long arching branches that sprout from a central root ball. These branches drop seeds away from the root ball onto new open ground. The branches are also very wiry so in high winds they can act like whips to fling seeds further a field. Due to the small round shape of the seeds, they are easily washed into storm drains and creeks, this being probably the most common form of seeding in urban areas. Birds and some animals can eat the seeds, which are resistant to the acids in the digestive system, so they are excreted later in perfect condition to sprout in new locations.

Please note that privet seeds are slightly poisonous to humans, but they will kill a horse if eatten them.

The Privet Sculpture Project: Cutting Research


This is the edge of a native grass field that has never been plowed. It is slowly being overrun but a tidal wave of privet.

Anne Albagli and I went out to La Reunion Tx today. It was again damp, muddy and slick, but after whacking away at privet for an hour, the cold damp didn't feel so bad.

I brought along a cornucopia of saws, hedge clippers, and hatchets to test out. Branch trimmers work the best for anything smaller than an inch in diameter. Bigger than that you need a pull saw. Those come in lots of shapes and teeth counts. Lots of teeth seem to work the best. The privet is to wiggly for a standard push saw or an axe to efficiently cut lots of privet. I did notice areas where people had used a chainsaw. Agin the wiggliness of the branches resulted in heavily splinter stumps.

Make Space: Installation meet up at La Reunion TX

Old road almost swallowed up by privet

A good portion of the artists for this years Make Space: Installation met up at La Reunion Tx to scout out locations and inspirations for their installation projects. It was thick with slippery mud but other wise a very nice day.

Sarah Jane introduced me to Shreyas Krishnan, who describes himself as an ecologist with an interest in how invasive plants effect the natural evolution of amphibians and retiles. Of course I was very happy to hear about the invasive plant interest. I am hoping to include some of his knowledge in the documentation on the Privet Sculpture Project.

Two of the other artists, Anne Albagli and Nicle Cullum Horn are using privet in some form in their installations, so I'll be posting about some of their experiences here, too.

More Local Privet Problems



Seems like as soon as I submitted my Privet Sculpture proposal to La Reunion privet started coming out of my ears.

Lots of people like Shreyas Krishnan and organizations like the Texas Master Naturalists are very passionate about privet. Shreyas sent in this link to an article in the Dallas Morning News about the problems of removing privet from the Great Trinity Forest, (video by Scott Miller) Texas Invasives.org is actually creating a map that tracks the spread of privet across Texas.

On site with Make Space: Installation

Drove out to meet up with Sarah Jane Semrad and some of the other artists that are part of the La Reunion TX Make Space: Installation. The La Re Volunteers have been working had this past year to clear out new trails and spaces. I wish I had known, I could have collected a lot of privet.

Anyway here is the list of artist in this years show:
Anne Albagli, Oliver Bradley/David Blood, Sandra Groomer, Nicole Cullum Horn, Scott Horn, Kevin Obergon, Brad Ford Smith.

Privet Gone Wild at La Reunion TX

I am one of the artists in the 2010 La Reunion TX Make Space: Installation. My project is to make an architectural sculpture using privet. Privet is a plant from Asia. As you can see in the photo, it is a very aggressive and is quickly overtaking the Dallas Metroplex. Just about any creek or flood zone you look into you will see privet growing, acres and acres of privet. In this project I will be testing the viability of using the privet as a green and renewable building material.

Proposal for La Reunion Tx, Making Space: Installation


Privet: A non-native gone wild

During the time that I have spent at the La Reunion property it has always struck me how much the non-native shrubbery called privet has taken over the landscape. This plant, originally from Asia is very aggressive and hardy. It is used widely in the DFW metroplex as a decorative bush around houses and commercial builds. Unfortunately a single privet bush will produce 1000s of berries each year. These berries are often washed into the city’s storm drains which empty into the local creeks and streams. The result is that most of the creek banks and flood zones in the DFW area are now overgrown with privet. Once a privet bush is established, simply cutting it down cannot kill it. The root ball is like a Hydra, it will send up several new braches for each one that is cut off, totally replacing the old growth within a few short months. Privet is pushing out the native plants that native animals, birds and insects feed upon. This is creating vast areas of monocultures that only support other aggressive plants like poison ivy and insects like mosquitoes

Privet: An experiment in repurposing

The branches of privet are very long and thin, but also surprisingly strong. In this way privet resembles plants like the ocotillo, cane and bamboo, all fast growing plants that are widely used as building materials. Based on these natural characteristics, a team of artists will “harvest” privet branches from the La Reunion property and use them to construct a sculpture. This sculpture will be of a design and scale that calls explores the architectural validity of using privet as a building material. Documentation and photos will be taken throughout the project. After 12 months the sculpture will be dismantled, at which time documentation will focus on the condition of the sculpture and the structural stability of the privet.

If this field test proves that privet can be used as stable building material, it could turn the urban privet plague into a valid source for sustainable and green building materials
