Thanks Mary Ann.. Years ago, Dave told me that one of his friends was getting rid of it. When he described it to me, I wasn't interested. I thought it was going to be like those redwood burl tables that were ubiquitous in the 60's-70's.. Then I saw it, and gave the ok... We bought our couch to fit around it. The base is Monterey Cypress "fingers" holding up the top.
I also used to plant black tulips (either 'Negrita' or 'Queen of the Night'), but with pink tulips.. That might also be fun with Iris.. hmmmmm.
