As an experiment, I started a Jerusalem Artichoke. I’ve read that they can be “invasive” so I planted one tuber (about the size of my fist) in this blue plastic container. I want to evaluate the merit of having this flowering plant in the large area adjacent to the parking lot. It would be inconsiderate (of me) to plant in a community garden area and have it “take over.” I found the article, from Mother Earth News, to be very informative. ~~ I purchased the metal “container” (for want of a better description) from Goodwill and thought it a satisfactory support for tender shoots (that require support). Later, if needed, I’ll provide a taller trellis.
Believe it or not, I passed up buying two large planters (today) at Goodwill. They were (are) large cement pedestal urns for $5. each. A very good buy because those sell for over $40. at Garden Ridge. But I had to question whether I need any more planters. These were (are) very heavy and I have tried to avoid having planters too heavy for me to lift. Correct me if I am wrong, I think the metal “container“ is used to carry tennis balls. (Yes, for tennis balls; I checked the Internet.)
Postscript, Thurs. April 18, 2013, 2:00 PM: This morning, the Jerusalem Artichoke displayed five or six shoots. Nothing yesterday!! This beautiful warm weather has prompted plants to miraculously “spring forth.”
