I poked holes in some plastic yogurt bins, filled them with potting soil and sowed herb seeds. I never fail to be amazed by the speed with which sturdy green sprouts unfurl from those tiny black beads. They seem to know exactly what to do, these seedings. They reach for the sunlight with both leaves. They reach for the water and soil with translucent surprisingly strong roots. And in between those new green leaves and those slender roots, they stretch and stretch.
