If you live in a temperate zone, I recommend choosing three-fourths perennials (or self-sowing annuals) to one-fourths annuals, so that your garden comes back year after year and you’re not always starting from scratch with your plantings.
Depending on where you live on the globe, some herbs may be perennials to you but annuals to another. If you live in a temperate zone, I recommend choosing three-fourths perennials (or self-sowing annuals) to one-fourths annuals, so that your garden comes back year after year and you’re not always starting from scratch with your plantings. Culinary medicinals like cilantro and fennel are annuals/biennials, yet I’ve not had to plant them in years as they keep self-sowing and making their continual patch. Some other medicinal annuals that self-sow are anise hyssop ( Agastache foeniculum), holy basil, chamomile ( Matricaria chamomilla), and sweet Annie ( Artemisia annua).
