What if you could have a garden that basically planted itself? The idea isn't as far-fetched as you might think. Self-sowing plants are delightfully serendipitous plants that will happily disperse seed without any intervention from you. Yes, there are lots of plants out there that spread indiscriminately and obnoxiously--but those are not the ones we are discussing in this episode. Instead, we're focusing on an array of perennials, annuals, and even edibles that will create offspring politely--filling in gaps and blank spots in your beds and borders. The English have embraced the idea of self-sowers more readily than gardeners stateside, but on today's podcast we argue that opportunistic plants have a place in virtually every garden. Listen now to find out which self-sowers dance through our gardens (and driveways).
