We have a string of comments going on Toby’s sedum post, and now I’m going to add another question to the mix: is there evidence that sedum won’t escape from rooftops and become invasive in places where it may be unwelcome? It’s being used so heavily in green roof construction, and being pitched as a [...]

Question: Mixing Soil

How is it done? What kind of equipment is used? What does it take to assure a consistent blend?
Question: Sedum Performance
Posted in Plants, Questions on November 22, 2008 | 8 Comments »
Two advantages of green roofs are their ability to cool the building below and the air above, and to reduce stormwater runoff volumes, thanks to the transpiration of moisture through their leaves. The most common green roof plant are species of Sedum. Those plant can survive drought conditions in the rooftop environment in part because [...]
Question: Inorganic Mulch and Girdling Roots
Posted in Plants, Questions on November 22, 2008 | 1 Comment »
Mulching against tree trunks promote adventitious roots, some of which can grow into girdling roots that weaken the tree.
Does this pertain equally to inorganic mulches, such as pea stone? Do they promote adventitious roots, and if so, do those grow into girdling roots? If inorganic mulches offer advantages, what practices are required to maintain those [...]

Teucrium
Posted in Plants on July 18, 2008 | 2 Comments »
Just a quick little post, to mention the idea of working with plants to achieve a design idea. An email arrived last week from a client when I was out of town, telling me that bees had started swarming all over the Teucrium we’d planted near the new spa on her property. She’d had the [...]
Grown to fit

It’s true; there is something odd about taking a field-grown specimen tree or shrub, full on all sides (and often pruned to make it look even fuller, a practice that sometimes drives me nuts), and placing it in a spot where it won’t get as much sun and where it’ll look a bit off for [...]
They clean up nicely

Last year I did a little pruning on a River Birch planting that had been in the ground for about 4 or 5 years. They’d been planted pretty close — 5 feet or so — to a driveway, and the lower branches were waving out into the roadway. (They were also 6 or 7 feet [...]

I like the idea of the plants finding their place and relationships together. This also works on the level of the individual plant. The smaller the plant, the better able it is to adapt its habit to its circumstances. Any tree planted, say, in a location with a lot of light on one side and [...]

Maine, Memorial Day weekend 2008. St. Columba’s Memorial Garden, Boothbay Harbor. Interment of ashes. Sun raining through spruce and pine boughs lit up the yellow bell-like flowers of Clintonia borealis (Blue Bead), and brightened to even brighter whiteness the Trientalis borealis (Star Flower) flowers carpeting the ground. Walking around the woodland knoll felt like walking [...]
