Many annuals and perennials drop their seeds after they bloom, then those seeds grow and flower the following season, creating unexpected, intriguing new partnerships with other plants in the garden. These self-seeding flowers are also useful because they sprout up and fill open areas of the landscape that would otherwise be prone to colonization by weeds. And, because self-seeders emerge where conditions suit them best, they perform as well, or better, than painstakingly nurtured plants.
I'm thinking about gardening as a radical political act.
