BAGSC’s Ficus Exhibition at The San Diego Botanic Garden’s Ecke Hall opened on Thursday, November 2, 2017.

In addition to written posters describing the morphology of the Ficus species, leaf rubbings, ink prints, sketches and color studies complement the educational component of the exhibition. © 2017, Janice Sharp. Photo by Olga Ryabtsova, © 2017.

Nineteen Ficus artworks, by 11 artists, are featured in the exhibition. A wonderful diversity of techniques have been used by the artists. In addition to the “traditional” watercolor, colored pencil and graphite there are leaf ink prints, graphite leaf rubbings, linoleum cut hand colored prints and tape-mounted fig wasps. Three written posters describing the Ficus species, their fertilization and biology provide an educational component to the exhibition.

Thank you Cristina Baltayian, Cynthia Jackson, Susan Jackson, Arillyn Moran-Lawrence, Lesley Randall, Robyn Reilman, Olga Ryabtsova, Janice Sharp, Deborah Shaw, Beth Stone, and Anna Suprunenko for your participation and for making the show a success.

In preparation for the upcoming BAGSC Exhibition, Ficus at San Diego Botanic Garden, here is a bit of information about this extraordinary group of plants.

We’ll start with the one most of us know best: the edible fig. Ficus carica, has been in cultivation since ancient times. Though humans typically eat only this species of Fig, others are considered to be keystone species in their habitats, providing food (leaves as well as figs) and shelter for a wide variety of mammals, birds and insects. Several species are plants of special significance in many cultures. For example, Ficus religiosa, the Bo Tree, is said to be the tree under which Buddha sat while gaining enlightenment.

Some figs are cauliflorous, a botanical term for plants which have flowers and fruits growing directly from their main stems or woody trunks rather than from new growth. The word comes from Latin. Caulis means trunk or stem and Flory means flower. Photo by Lesley Randall, © 2017.

The genus Ficus is a member of the Moraceae, or Mulberry Family. There are more than 800 species of Ficus. Most are tropical, but there are some species that survive in more temperate zones, such as the edible fig. The genus is highly diverse, with species growing as epiphytes, massive banyans, stranglers, shrubs, caudiciforms, vines and small trees. They are found from rainforests to dry rocky deserts.

 

So what makes a Ficus a Ficus?

There are a couple of key characteristics that separate this group. First is the unusual flower/fruit arrangement—the fig itself. Known as a syconium in botanical lingo, the fig is an urn-shaped structure lined with tiny flowers on the inside. The flowers are pollinated by a specialized group of wasps that enter the syconium through an opening called an ostiole.

The second key characteristic are the paired stipules that enclose the developing leaf. Though these often drop off as the leaf begins to unfold, they leave a distinct scar at the base of the leaf. The stipules may be separate, or fused into one structure.

The third key characteristic is the sap: a striking white or yellow latex.

Other characteristics to note are: an alternate leaf arrangement, and typically, pinnate venation. All figs share these characteristics that, combined, distinguish them from other plant genera. How these characters are expressed are what makes the group so interesting. The syconium can be as large as a baseball or less than a centimeter wide. It may be scaled or smooth, sessile or stalked and borne in leaf axils or on the main branches and trunk (cauliflorous.) The leaves are typically entire, but several species have lobed leaves. Leaves may be thick and tough, light and delicate, very large or very small. The bark can be smooth, rough, or in the case of a couple Australian species, corky and fire retardant.

Where to find Ficus in Southern California?
The Los Angeles County Arboretum & Botanic Garden, San Diego Zoo, and San Diego Botanic Garden all have nice collections. The Huntington Library, Art Collections and Botanical Gardens have some as well. They also can be found in parks, lining city streets, in back yards, as house plants, in nurseries and as Bonsai specimens.

Want to learn more? Check out Fig Web which has information on specific species as well as general information on the group. BAGSC members who are interested in organizing and/or attending expeditions to find and paint specimens should let us know your interest and stay tuned!

Information about the Ficus exhibition at the San Diego Botanic Garden can be found on BAGSC’s website. Information about the “Call for Entries” can be found on the “Members Only” page of the BAGSC website.
