Los Altos Hills, two acres with poppies, were formerly a weed field until Ecological Restoration started, at the corner of Anacapa and Viscaino.

The best wildflower planting in the Bay Area is in Los Altos Hills. Park at the corner of Anacapa and Viscaino when you drive up from Purissima, then walk down Viscaino past the first driveway of the left, and that is where the picture above was taken. .

My company, the Reveg Edge put together the plan to manage the two-acre hillside, normally choked each year by the fire-hazard European weed grasses, and convert it back to 100% local native and weed-free vegetation, by using Ecological Restoration.

Ecological Restoration can produce the best sustainable landscaping solution--By changing the ecology back to what existed, when everything was native.

Step-by-step Ecological Restoration strategies are:

(1.) Identify the natives
that are already growing on the property, because then you can conserve and protect them, so they can convert more weed areas.

(2.) Mow weeds when green each spring, before the stems turn brown--That way you eliminate a whole new generation of weed seeds sprouting next year. Always mow gigh, 8-12 inches, never lower or you could cut natives.

(3.) Rake off all of the cut weed straw, because that straw contains natural herbicide-like chemicals that keep the native seeds from sprouting or thriving. The weeds are like parasites to the natives, stealing nutrients and space that the natives need to survive. Use the straw to put on larger weeds like Italian and Yellow star thistles.

(4.) Soil tests to see what the native plants need, and add the proper organic fertilizers to feed their seedlings.

Once the land is properly managed, native wildflowers and native grasses may sprout up on their own, without sowing a single seed--California native seeds can lay dormant underneath the weeds, sometimes 100-250 years.

The basic rule of thumb, in April each year, if you only see green on the hills of California and no wildflowers in that area, you are probably looking at a solid patch of European weed grasses, and the local native plants need our help to survive and recover.

So, convert the unirrigated parts of your property back to solid wildflowers, and native grasses--Why keep mowing a weed patch each summer, when just by adding Craig's Ecological Restoration process, you could have wildflowers instead?

My process for homeowners starts, by go through the property with the owners and/or landscape managers and take samples of the native plants and the weed plants, and tape those examples into file folders, so that the property owners can have examples of what needs to be managed, and what plants need to be conserved.

The properties that I have worked on, located east or west of I-280, always have a few natives hidden under the oaks, and discovering what natives are left gives us an excellent clue on what to convert the land to in the future.

That means each property in Hillsborough, Woodside, Portola Valley, and Los Altos Hills have the potential to get back to their original local wildflower beauty days.

NUMBER OF HOMES on the Peninsula, in the place of weed-patches, could have native grasslands and wildflower fields?

HILLSBOROUGH - Converting the unirrigated areas = 3,696 homes.
LOS ALTOS HILLS - Converting the unirrigated areas = 2,829 homes.
PORTOLA VALLEY - Converting the unirrigated areas = 1,746 homes.
WOODSIDE - Converting the unirrigated properties = 1,977 homes.

TOTAL unirrigated areas around homes, that could be future wildflower fields = Over 10,000 !

"When you look out any window, you deserve to be looking at a masterpiece landscape like something painted by Claude Monet, because you paid for that view
--Adding the original native plants will give your place that charm and beauty that had already existed for thousands of years. It is like cleaning off a painting and finding an original Rembrandt underneath."
