Her past green roof projects had been designed around available landscape plants. Choose the typical on-the-ground landscape plant and design irrigation and fertilizer and other accessory design criteria to support the landscape plants - was the motto.
Whenever we'd discuss native species or volunteer species showing up on the roof, she'd immediately try to quash the discussion by shouting 'WEEDS! NO ONE WANTS WEEDS ON THE ROOF!'
I think it was because she felt uncomfortable trying to work with the organic, dynamic complexities of nature. Obviously she wanted no part of having native plants or wildflowers or grasses on the roof. Moreover, I've seen some of her 'landscaped' green roofs and they quickly revert back to natives, or as she calls them 'weeds'. I am sure selective herbicides are used quite often on her green roofs and with obviously little luck.
Now is the time to stop. We must stop seeing masses of green and train ourselves to look at the plant. There are few if any true worthless weeds in nature and likewise few, if any true worthless weeds on green roofs or across the Urban Core.
Each plant has its own beauty and purpose, even those obnoxious ones.
I've often quoted Lydia Cabrera in saying "there are more spirits in the plants/forests than in the sky'.
The vegetated roof in Sanford I toured this week was full and vibrant due to volunteer plants.
Really, there are no true worthless weeds.
I heard the weed thing again from my daughter, today.
She showed me her photos of one of the most obnoxious plants in my book - Bidens alba (Hairy Beggar's-tick). Just try walking through a mass of Bidens and wait till you come out the other end of the patch....
I love their masses of white flowers but distrust their desire to bestow me with masses of aggravating seeds.
I almost at this time of the year agreed with the self-centered technocrat who probably couldn't tell bamboo from horsetail or coral honeysuckle from trumpet vine. I almost shouted WEEDS!
But Jincy showed me her pictures from today. Ones she and Ruairi took out back. The Bidens are growing on the roof too.
And Lydia Cabrera is right about more spirits in plants. And I am right about 'there really are no weeds'....
No need to weed the Bidens from the back yard or the corner lot or the green roofs. Just step back and admire the flowers and astonishing numbers of pollinators drawn to this plant.
