Bay seniors who’ve scaled down their horticultural activities to the top of their kitchen counters might want to try their hand at creating Apothecary Jar Art Gardens. Lucky for you there’s a class in creating these miniature fantasies at the SF Botanical Garden on February 22 from 2-5. All materials including mosses, miniature ferns, lichen covered branches, small bones(!) and the jars themselves will be provided. Bring along any curious small whimsies of your own. Non-members $90.
