This technique, sometimes called direct sowing, involves placing the seeds outdoors in your garden right where you want them. This works with a variety of annuals, but there are a few varieties of tender annuals like sweet alyssum, poppies, sweet peas and larkspur that need to wait until after the threat of frost has passed. But for these annuals, direct sowing is a good choice anytime:

  • Cosmos
  • Castor bean
  • Calendula
  • Morning glory
  • Bachelor button
  • Sunflower
  • Zinnia
  • Annual poppy
  • Marigold
  • Hyacinth bean


Other seeds do better indoors. Place these seeds in soil under lights, then wait six to eight weeks to see the results. Smaller seeds should start in a seed tray. Once they’ve sprouted, then they can be transported into separate growing areas. Here are the varieties this is a good choice for:

  • Salvia
  • Impatiens
  • Petunia
  • Statice
  • Cleome
  • Snapdragon
  • Nicotiana
  • Ageratum
  • Amaranth
  • Coleus

Why choose seeds?

One major reason to start plants from seeds is that they are far cheaper than buying mature plants, costing as little as 10 percent of a grown plant. That means you can spend that money you’ve saved on plants on other gardening essentials.

Another major reason is variety. Every garden center can’t carry all the annuals green thumbs are looking for. If you have particular favorites that you’ve been wanting to grow, then choosing to do so using seeds is the way to go. Most annuals are relatively simple to grow from seed. The biggest challenge will be finding the right spot.

Consult your local experts about the best conditions for each seed, such as how much light they need, how much moisture they need, whether they’re frost hardy or not, etc. You’ll also want to ask about special germination requirements and determine how long the seedlings will take to grow in your garden.
