The farm was his laboratory - not the tidy, climate-controlled kind, but the sprawling, dirt-under-the-fingernails kind where 60,000 plant experiments ran simultaneously and a crew of fifteen to twenty workers tended rows of trees, shrubs, and perennials that Burbank was crossing, grafting, and selecting with the patient urgency of a man who believed he could improve nature itself. Today, three of those eighteen acres survive. The rest became senior housing. But those three acres still hold over 250 living specimens of Burbank's work - plants he bred more than a century ago, still growing, still bearing fruit.
