For a native plant novice like me, joining the California Native Plant Society seemed like a good idea so I became a member of the San Luis Obispo chapter. My spouse and I attended our first meeting a year ago last October. That is where I met Marti and the real fun began.read more
Last month we discussed California ground squirrel problems, this month I will focus on the gopher aka Botta’s pocket gopher (Thomomys bottae). For most of us, gophers can sometimes be a headache but a livable one. They come and go between you and your neighbor’s yard, only losing a couple of plants a year. For yards like these I recommend using …read more
The cover of this Obispoensis is another beautiful water color by Heather Johnson. In our area Hummingbird sage can grow in an extensive mat. Its leaves are large (10 in (20 cm) long and 3 in (8 cm) wide). The leaf surface appears quilted. Its family affiliation (Mint or Lamiaceae or Labitae) is shown clearly in Heather’s water color.read more
California Dudleyas are easy to grow. Illegal wild collection can be disrupted via legal propagation. I propagate Dudleya with middle school science classes. If seventh-graders can grow these natives from seed, you can too. Home gardens are a good source of Dudleya...read more

Saturday, Dec. 2nd, 9:00 am to 12:00 noon
New Reservoir Canyon Trail Plant Walk
Join us for a plant ID walk in Reservoir Canyon and the new trail that leads to Bowden Ranch. The focus of this fieldtrip will be riparian and serpentine plant communities, plants one would regularly encounter throughout much of the greenbelt surrounding the city of San Luis Obispo. It is 4 miles up and back, ascending 800 ft. The ascent is gradual, along a winding trail towards the top of the ridge. Come and learn the easy to identify species. Pick out plants that attract you. Bring native plant samples with you to be identified.
Meet at Santa Rosa Park in SLO at 8:45 am (to car pool to the trailhead) or at the Reservoir Canyon trailhead at 9:00 am (parking can be limited). Make sure to bring water and snacks. Sturdy shoes, sunscreen, hats, and layered clothing are recommended. No RSVP needed and no dogs please. Also, bring paper and pencil to take notes, and a camera for a photo record. If you would like a preprinted copy of the plant list for this walk, let the hike leader know 24 hours in advance.

Program: Travels with a Geobotanist: Plant Life on Serpentine and other Harsh Soils with Dr. Nishi Rajakaruna
Dr. Nishi Rajakaruna fell in love with plants at a young age during a visit to Sinharaja Rainforest, Sri Lanka. He received a BA in human ecology from the College of the Atlantic, and an MS and PhD in botany from the University of British Columbia. He conducted post-doctoral research in plant ecology at Stanford University. His research examines how plant diversity, ecology, and evolution are influenced by serpentine and other ‘unusual’ soils, including those with heavy metals. He has taught botany at College of the Atlantic and San Jose State University during the last 12 years and is currently an associate professor in plant biology at California Polytechnic State University.
