How many sunflower plants are we supposed to plant?

Not sure if we are only supposed to plant just one, just two, that it doesn't really matter, or as many that come in the seed packet.

How many seeds to plant

Please plant the number that work for your garden. Our seed packets contain 30-60 seeds and we expect an 80% germination rate. You can decide to plant just one or better yet, plant a couple a month and you'll have sunflowers right through September.

Gretchen, Thank you for this

Gretchen,
Thank you for this suggestion. What a wonderful idea to have sunflowers all season and not just for a short time.
