Reflecting Seasons

Native plants “spring” to life in early winter during the winter rains, with flowering periods starting at that time and running throughout spring. As things heat up in the summer, some of the local natives, those that are not evergreen, go dormant, which some people consider a disadvantage.

In one sense, this opposition to natives may simply be a matter of personal taste. There are also people for whom the whole process of dormancy can look beautiful. For example, the leaves of the Black Sage (Saliva melifera) begin to brown in June after the plant has finished flowering. Some of the leaves fall off right away, others remain for different lengths of time. This leads to beautiful contrasts between the ones that are still dark green on the top sides, the bottom sides of others that are light green, and those leaves that are turning different shades of brown.

There are also ways in which opposition to dormancy may be more than simply a matter of taste. On a conceptual level, it is strange that so many people are unfamiliar with the idea of summer dormancy, even people who were born and grew up in California. To me, this fact demonstrates the extent to which imported horticultural standards dominate or condition our expectations of what a garden should be, and even of what nature should be. What seems even stranger to me is that in the East the concept of dormancy is accepted, and even appreciated during the winter. However, this tolerance for dormancy was not imported alongside the Eastern lawn-based traditions.

Whatever the cause, we seem to have learned to expect plants and lawns to behave as if we lived in New Hampshire, or Georgia, or as if we were in the tropics and San Diego were a Hawaiian island and not a desert climate. Whatever the causes, to fulfill these expectations and ideals we certainly water the heck out of our yards throughout the summer to attain them.

I suspect that underlying the adoption of these foreign horticultural standards is the sentiment that seasons just get in the way. People want their gardens to reflect a constancy and uniformity that defies nature. Because of the mildness of our climate it has been possible to achieve this ideal, but we are slowly coming to realize the extent of the costs of this sentiment, and that it leads to waste on a very large scale.

Besides the incredible waste of resources, I believe that the most unfortunate result of the horticultural ideal of making our gardens look the same year round is a growing disconnect between people and the nature that surrounds them. It is not hard to see how this disconnect has lead to damaging consequences for the environment.

Were we to learn to value the concept that each region should reflect its own character, there would be less problems with invasives. One step in this process is to plant a native garden. Very simply, by planting natives you decrease the number of invasives that are planted. Hopefully, helping our neighbors become familiar with natives in this way will lead them to do the same, and the use of invasives could really decline.

To me, it is a dynamic prospect that using local natives not only helps conserve resources but can also strengthen the image of San Diego as having its own identity, and that this in turn could help inspire people to preserve the natural environs that we have outside of the garden domain.

Of course, one downside of expressing individuality in this way is that planting a native garden goes against a strong current of traditional horticultural conditioning. That is, going native would seem to put one directly at odds with a blind, powerful force in the world that makes money by perpetrating and maintaining a dead-end horticultural direction.

Fortunately going native is not as scary as this sounds. All the drama one may feel associated with such a change in direction dissipates quite easily from the simple act of placing a young native plant in the earth and watching it grow. How refreshing that such a simple action can undo years of misdirection.

Assembly Bill 1408, authored by Assemblymember Paul Krekorian and co-sponsored by PCL and the East Bay Municipal Utilities District, provides a new tool to allow communities to accommodate growth without increase water demand. AB 1408 would institute a water neutral development option that developers and water agencies can voluntarily choose to utilize during the development approval process. The bill would encourage developers to build highly efficient houses, and further encourages developers to fully offset the water demand of the development by taking part in water conservation programs for existing homes and businesses.

AB 2717, AB 1881
http://www.owue.water.ca.gov/landscape/ord/updatedOrd.cfm

In 2004, AB 2717 was passed, it requested the California Urban Water Conservation Council (CUWCC) to convene a stakeholder task force, composed of public and private agencies, to evaluate and recommend proposals by December 31, 2005, for improving the efficiency of water use in new and existing urban irrigated landscapes in California. Based on this charge, the Task Force adopted a comprehensive set of 43 recommendations, essentially making changes to the AB 325 of 1990 and updating the Model Local Water Efficient Landscape Ordinance. The recommendation of the bill charges DWR to update the Model Efficient Landscape Ordinance and to upgrade CIMIS.

The Water Conservation in Landscaping Act of 2006 (AB 1881) enacts many, but not all of the recommendations reported to the Governor and Legislature in December 2005 by the CUWCC Landscape Task Force (Task Force). AB 1881 requires DWR, not later than January 1, 2009, by regulation, to update the model ordinance in accordance with specified requirements, reflecting the provisions of AB 2717. AB 1881 requires local agencies, not later January 1, 2010, to adopt the updated model ordinance or equivalent or it will be automatically adopted by statute. Also, the bill requires the Energy Commission, in consultation with the department, to adopt, by regulation, performance standards and labeling requirements for landscape irrigation equipment, including irrigation controllers, moisture sensors, emission devices, and valves to reduce the wasteful, uneconomic, inefficient, or unnecessary consumption of energy or water.

Going green, without a lawn

Virtually all the bungalows in Jennie and Chas Rightmyer’s Kensington neighborhood have well-tended lawns out front – part of the American dream, along with picket fences and two-car garages.

But increasingly dire warnings about statewide water shortages prompted the Rightmyers to remove their Bermuda grass. They are replacing it with a drought-tolerant garden that should be completed by month’s end.

The couple hope the new landscaping will cut their overall water use by more than 20 percent.

“It just feels like the time has come,” Jennie Rightmyer said.

Californians should end their love affair with lawns, said water officials, lawmakers, conservationists and landscapers. Many of these advocates have promoted native plants for years, but they now sense a greater potential for change because of the public’s growing concerns about global warming, drought and ever-rising water bills.

“It’s the beginning of the end of lawn at home,” said Nan Sterman, who teaches a class called “Bye Bye Grass” at the Water Conservation Garden in El Cajon.

Last week, the garden’s managers started a hotline for people to seek advice from Sterman about “water-smart” landscaping.

“It’s not just the early adopters anymore,” Sterman said. “It’s (average) people who are really getting the sense that we have to do something . . . which tells me that it’s becoming part of the mainstream.”
