When you plant your garden using self-seeding plants, you are planting a garden that is as low-cost as it is low-maintenance. For most of us who lead busy lives and have several demands on our time, energy, and bank accounts, this is the best kind of garden to have.

These plants all reseed themselves so that you don’t have to do much of anything from year-to-year. Just plant, water, harvest and let them be.

Tips For Growing Self-Seeding Plants

Before we get into what to plant, read through these tips to give your self-seeding plants the best possible opportunity to flourish (1):

  1. Plant heirloom varieties
  2. Don’t deadhead (you want to encourage blooming)
  3. Educate yourself on each growth stage of your plant so that you don’t mistake them for a weed the following spring.
  4. Plant your self-seeding vegetables in their own patch, separate from non-self-seeding plants.

Keep all of those items in mind when choosing which plants you will use in your garden. Let’s begin with the flowers.

3. Parsley

Often used primarily as a garnish in restaurants, parsley can add a lovely bit of flavor to your dishes. The first season you plant parsley, harvest it as normal.
