Sunflowers are one of the most versatile annuals sprouting in summer gardens. They grow in zones 2-11, which means that you most likely live in a location where these bold blooms can thrive!

Here is an excellent growing guide that outlines the different zones throughout the United States. Red sunflowers grow in every state, although there are a few colder concentrated areas where they will not thrive.

Where To Plant + Soil Conditions

Luckily for flower lovers like us, red sunflowers are an amicable flower that are not too picky! They are one of the few flowers that can thrive in poor soil.

For best results, however, plant in well draining soil in a location that receives full sun, and if possible plant in soil that has some nutrients.

Full sun means at least 6 hours of direct sunlight, but sunflowers do well in even longer direct sunlight conditions! They are called “sun” flowers for a reason!

You do not have to have rich, nutrient dense soil for red sunflowers, this is a flower species that can thrive in any soil.

When possible, choose a location that is out of direct wind, or sheltered in some way. Due to their long stalks, sunflowers are susceptible to damage from wind.

Are Red Sunflowers Annuals Or Perennials?

Red sunflowers are annuals, which means that they bloom for one season and do not come back the next year.

If you let sunflower seeds fall to the ground, you may end up with volunteer starts the next year. Of course you will be betting against birds (who gobble up sunflowers seeds in a flash!), rot from rain, and wind.

The best way to ensure you have sunflowers in the following season is to collect the seeds or re purchase and plant them in the spring again.

How Tall Do Red Sunflowers Grow?

On average, the height of red sunflowers is 60 to 72 inches, or 5 to 6 feet tall. However, the height of red sunflowers depends on the variety that you are growing.

Dwarf sunflowers only grow a few feet high, and many varieties, such as Autumn Beauty, can grow over 6 feet tall in the right growing conditions.

How To Plant + Grow Red Sunflowers

Planting red sunflowers is very easy. You can grow your seeds straight in the ground once all frost danger has passed or start them indoors earlier in spring.

Planting Directly In The Ground:

Wait until all danger of frost has passed. If you live in a particularly rainy area, you may also want to wait until the rainy season has passed to prevent your sunflower seeds from rotting. Then:

  • Dig a hole or trench in soil about 1/2 inch deep
  • Space red sunflower seeds 6-8 inches apart
  • Place 2-3 seeds in each spot
  • Cover loosely with 1/2 inch of soil
  • Water lightly (soak but don’t drown your soil!)
  • Continue to water regularly, keeping soil damp but not soggy
  • Watch regularly for seeds to sprout, (about 10-14 days)
  • As seedlings grow, remove weak seedlings by cutting them at base

Tips For Seedlings: Sunflower seeds can be susceptible to rot, so be sure to monitor the soil and make sure it’s not sodden. Seeds are a favorite snack for many birds, bunnies, etc, so if your seeds don’t sprout within a few weeks you may need to re plant!
