California Bees & Flowers: A Selective Love Affair

Speakers: Sara Leon-Guerrero

Date: September 18, 2014 (doors open 6:45 pm, Speaker at 7:30 pm)

Location: Duck Club, Irvine (Directions)

Covering native bee ecology, bee-plant relationships, and the implications they have on habitat gardening, this talk provides the listener with knowledge to start encouraging native bees at home. With 1,600 bee species in California alone (nearly 40% of the total diversity in the U.S.!), native bees are an important part of California's natural history and essential to the health of our diverse ecosystems.

CHINO-PUENTE HILLS:In early June, the Brea City Council voted 4-1 to approve the long-contentious 162-unit Madrona (aka Canyon Crest) project. Background and details:

Hills For Everyone, which has campaigned for decades to preserve open space in the Chino-Puente Hills, is now fundraising to fight this decision in court. 

ACTION NOW!:  Go to donate directly to the litigation fund.
Also HFR is hosting a Wine and Cheese Event with a silent auction on Saturday, July 19th, to fundraise. Tickets are on sale now: $30 per person or $50 for two, both $10 more at the door. Buy tickets in advance at

SADDLE CREST:The lawsuit, in which CNPS/OCCNPS is a co-defendant with four other enviro groups, continues to wind its way through the legal process of briefs, motions to strike, opposition to motions. It is expected that the Court of Appeals will deal with all these when it considers the merits of our case--which maybe will be in another 2-3 months. In the meantime, fundraising to cover our side’s legal costs continues.

ACTION NOW!:  Go to to donate--be sure to indicate the Saddle Crest litigation fund. A generous supporter will match donations dollar-for-dollar, up to $911.00.

Native Gardener’s Corner—Members’ Tips, Tricks, and Techniques

This column is a regular newsletter feature offering chapter members and local experts a chance to briefly share information on many things related to gardening with natives. Answers are listed in the order received.

Our question for this Newsletter is “What native plant has been successful in your garden, even though you planted it in the summer months?

Thea Gavin *

Rama Nayeri: “I have found that Autumn Sage, California Woodland Strawberry, and Yerba Buena tend to work really well in my clients’ gardens.”

Bob Allen: “Buckwheats!”

Chuck Wright: “I only plant in late fall and winter and early spring, except for cactus, like opuntia when it drops its pads. I will plant the pads with the edge facing south and a rock supporting each side and that seems to work.”
