Bees are humming, birds are chirping and hummingbird feeders decorate eaves all over Flagstaff. Signs of spring abound, and for all you gardeners, it’s time to plant! Now that snowfalls have come and gone (fingers crossed), our visions of lovely flowers and tasty vegetables are foremost in our minds.
To help get you started, the Coconino Master Gardener Association (CMGA) in partnership with the Coconino County Cooperative Extension's Master Gardener Program and the Museum of Northern Arizona are holding their free annual Plant Sale and Garden Festival on Saturday, May 24. Even if growing isn’t quite your thing, you’re sure to find something that delights!

Bird Walk at Kachina Wetlands May 17
Bird Walk at Kachina Wetlands
May is an excellent time to look for birds in Kachina Wetlands. Most of the summer residents have arrived, and there can still be species that are migrating through. Northern Arizona Audubon has two outstanding birders who will be leading the trip: Sky Schipper and Tom Hedwall.
Meet at the entrance to Kachina Wetlands. Bring binoculars if you have them, and don't forget your sunscreen, hat, and water bottle.
Plant Sale Volunteers
To: Master Gardeners and Future Master Gardeners
The CMGA is starting to plan for the 2025 Plant Sale to be held on May 24. We are in need of 15-20 volunteers to help with parking, general assistance for visitors, staffing a Q&A table, set up/tear down, and assisting in other ways. There are usually two shifts between 8 am and 3pm on Event day, plus prep work to be done on the two days prior.
This is an excellent way to get involved and to earn volunteer hours toward getting or maintaining Master Gardener certification. Plus, it is a lot of Fun!!!!
For all inquiries and to sign up to volunteer please send your contact information( including phone number) to us both at dnashmg2@gmail.com. and rguzley@sbcglobal.net We will send you an acknowledgement that you are on the list within a week.
Thanks so much,

Arizona Native Plant Society meeting May 20
At 7 pm on May 20, Dr. James Smith from the Snake River Plains Herbarium at Boise State University will present recent research on spring parsley (Pseudocymopterus) that indicates the spring flowering and summer flowering populations are separate species.
Arizona Native Plant Society talks are free and open to the public. This meeting can be attended via Zoom or in person at the NAU biology building third floor classroom. To attend via Zoom, register with this link: https://bit.ly/FlagAZNPS25
Spring parsley (Pseudocymopterus) is known to be highly variable morphologically and in its phenology. Dr. James Smith will present preliminary results that separate what we commonly call Pseudocymopterus montanus into several separate well-supported clades. Likewise there will be preliminary phylogenetic analyses that seem to separate most other species of Pseudocymopterus (P. beckii, P. macdougallii, and P. davidsonii) into spring flowering and summer (monsoon) flowering populations that have independently adapted to the different precipitation patterns.
This will be a virtual event with Dr. Smith presenting from Idaho. This presentation will not be recorded.
Dr. Smith is the Director of the Snake River Plains Herbarium at Boise State University. His research interests include the phylogenetics of western North American Apiaceae and using Sanger sequencing, and more recently Next generation sequencing techniques to discover cryptic or near cryptic species within many widespread species.
