In a world dominated by extroverts, it seems unlikely that gardeners, in general, are introverts. Gardening is such a personal means of self expression, and an emotional one as well, that it seems it might appeal to those, like myself, who dearly need a lot of time spent alone. Of course, gardening can be extremely social as well. It certainly is here in Portland, where, in springtime, hundreds of gardeners pot up their cuttings and offshoots to sell, usually out of their yard, garage, or (lucky them) greenhouse, to other gardening Portlanders.
This system is great for me. I'm not a people person, but I do like meeting and conversing with other gardeners. I always try to learn as much as I can. I've learned a lot from folks like Ms. Ott, whose dreamy urban farm paradise flourishes down the hill on Holgate Boulevard. I get my castor bean and Impatiens balfouri (poor man's orchid) starts from her. I also love strolling around her property, enjoying the glistening water of the rock pool, listening to the gentle clucking of the curious chickens, and noting the progress of her massive but very controlled raspberry brambles...the little ruby gems that eventually cover the bushes are some of the tastiest to be found in town.
After I visit Ms. Ott's, sometimes I go to visit Small World Plants, another homegrown business, with a slightly different focus. Owner Lee Kamrass offers out of her tiny greenhouse some of the most unusual and adorable plants I have ever seen. Most of her plants are naturally tiny or are dwarf cultivars of larger varieties. Come April, Lee's small but well organized yard will be full of colorful, infant, Japanese maples, succulents of all shapes an colors planted into tiny containers, petite evergreens, and, most likely, some fascinating new-to-me plants that I will marvel over then run home to research. My favorite acquisitions from Small World plants are the dwarf Sophora prostrata 'Little Baby', dwarf Juniperus communis, and my strappy little Gasteria excelsa.
So, gardening introverts...get out there this spring and see what other gardeners in your town are tending. You don't have to do much talking to communicate...gardeners can bond via the love of plants alone. Check out your local classifieds and see who's giving away or selling plants. Your neighborhood community center or church might offer a great selection and good deals as well. Set up an ad hoc plant sale in your yard or garage and give away or sell some of your own extras. Perhaps we introverts will bump into each other and become friends.
