Plants and Planning Explained

I was browsing in an Ashland, Ore. used bookstore a few weeks ago when a title caught my eye: “Consciousness Explained” by Daniel Dennett. Well, I thought, it’s about time somebody explained what’s going on in my head (if, indeed, my head is where “it” goes on). I read through a sampling and found it challenging but well-presented, so I took it home. For a few days I structured a four-course bedtime reading meal, with the Funny Times political comics for an appetizer, “My Weeds: A Gardener’s Botany” by Sara Stein for the salad, Dennett’s book for a meaty main course and some Eknath Easwaran for the spiritual sendoff to sleep.

A little too much bookage, it turned out ... Stein won, and Dennett will have to wait. Stein’s exploration of the lowly weed is proving to be no less of a mind blow than I expected from Dennett’s book, with scientifically precise gardener-relevant story-telling on topics like plant taxonomy, adaptation and evolution ... even “weed wisdom.” Stein’s not suggesting plants think the way humans do, or communicate on some mystical wavelength. Rather, she describes the mechanisms by which roots can “steer” around obstacles, vines can find and climb vertical objects, and a section of hoe-truncated bind-weed stem can recognize its position, growing down roots from the lower end and sending up a leafy stem from the upper end.

Statolith organelles in cells can determine up and down and trigger differential root cell growth. In addition, when the bindweed vine touches the cornstalk, the cells on the touching side send signals along the protoplasmic strands that connect through the pores of cells, giving instruction to slow their growth, while the non-touching side cells get chemical messages to grow faster. This uneven growth causes the vine to turn toward the stalk as it grows skyward.

The growth and development of a city like Petaluma is no less interesting than that of a weed. Much can be revealed by looking at it as carefully as a botanist considers a plant. This morning my wife and I were talking about the future of the Golden Eagle Shopping Center. We are hopeful that it will be transformed into a river-facing, mixed-use development with a generous public plaza, similar to Windsor or Healdsburg. The property is owned by Basin Street. They have expressed an interest in pursuing the remodel, but they face constraints just as a plant is constrained by its environment. The remodel requires money, like plants need energy. Some would come from their equity, from loans and from city redevelopment funds (the roots), but would have to be replenished by profits and taxes (sunlight and soil).

What combination of conditions will grow a redeveloped Golden Eagle? Basin Street has said they are not in a hurry to do the project, and claimed that problems with the city review process on the Theatre District makes them reluctant to start a new project. Is the city putting too much red tape on Basin Street, reducing the energy Basin Street can put into the project while yielding nothing of value for the public? Or is the city simply looking after the interests of present and future Petaluma residents, making sure that the design of buildings and infrastructure that will last a century or more does not sacrifice public good in order to increase the profits Basin Street harvests and removes from the site?

These questions can’t easily be answered without close-up, unbiased analysis. What exactly did the city require that Basin Street took objection too? How did it affect the project, and what did it cost Basin Street? How much money did Basin Street earn or lose? Are developers cycling part of their profits back into the political system, supporting City Council candidates who will demand less community benefit from developers, thus enabling higher future profits, continuing a cycle? But more importantly, what could be done differently for Golden Eagle that would support both the city’s and the landowner/ developer’s separate and common interests? If we can get the players in this drama to communicate as well as the cells of a plant, we might grow something truly wonderful.
