It’s easy being green this weekend, with the annual native plant sale in Santa Barbara and Avofest a bit farther south in Carpinteria.

Guac 'n' roll

Even though it’s green and savory, the avocado is actually a fruit, and technically a single-seeded berry. Does that make guacamole a smoothie? Find out at the California Avocado Festival (Avofest) this weekend on Linden Avenue in Carpinteria. Admission is free. Parking is $10 per car at Carpinteria High School (Saturday and Sunday only) with free shuttle service.

Food is abundant at Avofest, which is home to the world’s largest vat of guacamole. Food vendors try to outdo each other with dishes, including avocado ice cream. More than 75 musical acts perform on four stages, and the Expo Tent features farming information, restored tractors and the Largest Avocado Contest. Past winners have topped over 3 pounds!

Speaking of green

Just in time for the fall planting season is the Santa Barbara Botanic Garden’s Fall Plant Sale through Nov. 5. Fall planting season? That’s right. Fall is a great time to plant California natives, and the sale has more than 450 varieties to choose from. Get expert advice from staff and volunteers or be inspired by a walk through the gardens. The advice is free, but garden entry requires paid admission.

On Saturday at 4 p.m., author and landscaper Greg Rubin will speak at the Garden’s Blaksley Library in the annual Dara Emery Memorial Lecture. Rubin has more than 700 native landscapes to his credit, has won awards for his all-native Japanese garden at San Diego’s Botanic Garden and is co-author of new book “The Drought Defying Californian Garden.” Tickets are $30.

Can You kazoo?

Hip L.A. band Ozomatli brings its family-friendly Ozokidz show to UCSB Campbell Hall at 1 p.m. Sunday. Parents and kids alike dance and play along (on special Ozokidz kazoos) to songs that are not only catchy, but educational, such as “Trees,” “Skateboard” and the evocative “Moose on the Loose.” An Ozo concert is not to be missed! Tickets are $20 general admission, $16 for kids aged 12 and under. Come an hour early for preshow fun outside the theater. (893-3535, www.artsandlectures.ucsb.edu)

Bill Murray & Friends

Actor Bill Murray (“Groundhog Day”) sat next to German cellist Jan Vogler on a long airplane ride, and the two ended up collaborating on a CD titled “New Worlds.” The two bring their “New Worlds” tour to the Granada Theatre at 7 p.m. Friday, just days before appearing at Carnegie Hall.

Murray is both singer and narrator, performing songs such as Stephen Foster’s “Jeanie with the Light Brown Hair” and a “West Side Story” medley, and also reciting selections by Twain, Thurber and Hemingway, among others. Vogler and a small ensemble perform works by Ravel, Mancini, and Bach -- his Prelude from Cello Suite No. 1 will sound divine on Vogler’s circa 1710 Stradivarius cello. Tickets start at $54.
