Garden nasturtium is an easy-going annual that thrives in full sun to partial shade with minimal fertilizing — too rich a soil actually reduces flowering. Water regularly but avoid waterlogging, and deadhead spent blooms to extend the flowering season. Both the flowers and leaves are edible with a peppery flavor, making this a fun and functional addition to any garden.
