I first planted holy basil from a 4-variety seed pack I got at Strictly Medicinal Seeds. I planted the seeds directly into the soil and was disappointed when none of them germinated. Or so I thought. I eventually discovered, as it grew, that one little plant did take root. And every year I save its seeds for the next year, filling my garden beds with its fragrant medicine. I’m not sure which variety is the one that appeared. I don’t really need to know any more than it is the variety that wanted to stay with me, and it loves it in my garden. And I love it.
