Calls for Entries

We post Calls for Entries for Northern California exhibition opportunities which may be of interest to our members. For shows outside this area, you may want to check the ASBA site as well as other groups listed on our Links page.

Each exhibit has it’s own specific guidelines and requirements, but for general information about framing standards for NCalSBA members’ exhibitions please check here.

Note: When submitting an entry to a botanical exhibition, the scientific name of the plant is generally required. There are a number of rules about how these names should be written. If you are unclear about how to specify your subject material, you may want to look at a useful leaflet provided by the Horticultural Taxonomy Group (HORTAX) in the UK.

To research whether a plant is a native of California, you may want to use the Jepson Online Interchange California Floristics or the Calflora Search for Plants. If you are specifically seeking California natives, be sure to check that the plant is not listed as “naturalized in CA”

Mt. Tamalpais Florilegium

August – October, 2020

Deadline for entries July 31, 2020


Members of NCalSBA have a wonderful opportunity to illustrate and create a new florilegium of the plants growing on Mt. Tamalpais in Marin County.

We have another opportunity to have a tour with representatives from One Tam and the Marin Municipal Water District for the purpose of selecting plants for the Mt. Tam Florilegium.

Friday August 9,2019, 9:00AM until 2:00PM

We will meet at Rock Spring on Mt. Tamalpais. Directions, instructions, and guidelines to follow once you have signed up for the event.

Contact: Mary Gilardi to reserve your space. Space is limited so please reserve your space soon.

Plant List: Artists please go to the following MMWD web site to find the entire plant list for Mt. Tamalpais.

Special Instructions: Please disregard species noted (in red font) as non-native, and those “unsubstantiated” (species not found in watershed lands). Plants are arranged by family and have up to date correct names, and each species is accompanied by 2 color photos. Plants rare in the watershed are noted as such.

Also, here’s a list from CNPS the California Native Plant Society.

Artists may choose to paint/draw any of the listed plants. Artists need to inform one of the Florilegium managers of their choices in order to avoid duplication. The managers are Mary Gilardi, Laurel Kelly and Kristin Jakob.

If you have not already signed up to attend the May 17th collection Date please contact Laurel Kelly by May 13th to reserve your space.

Artists will not be allowed to take cuttings of some of the rare and endangered plants and therefore must be prepared to take photographs and sketch the plants on site.
