Full Sun Annuals for a Beautiful Yard

Full Sun Annuals

For areas in your yard that get full sun (meaning 6+ hours a day of sunlight), there is no shortage of gorgeous full sun annuals you can plant. And the best part about these beautiful annual flowers and plants is they are generally inexpensive and widely available. This means you can load up your yard with tons of beautiful color and texture without spending a lot of money.

Full sun annuals add gorgeous color to borders, walkways, flower beds, and containers. They can also add interesting textures and bold colors to your perennials that remain green most of the year. Some of the most widely used full sun annuals include petunias, strawflowers, zinnias, calibrachoa, sunflowers, and portulaca.

It’s important to check your planting zones when planting anything in your yard. You don’t want to waste money on plants that aren’t suited for your climate. This seems to be more relevant when planting perennials since you want those to return year after year. However, it’s a good idea to know your zone.

Full Sun Annuals

I’m breaking it up between annuals and perennials – this post is all about annuals that love full sun and I’ll include the planting zones that are most desirable for each.

But first – what’s the difference between annuals and perennials?

  • Annuals –  plants and flowers are considered annuals when they have to be replanted each year.  There are exceptions to this depending on your planting zones.  Certain plants can be considered annuals in one zone, but perennials in others depending on temperatures.
  • Perennials – these are plants and flowers that return year after year.  They will often require more attention in the first year or two after planting but will give you yearly color and variety without replanting.

PETUNIAS

ZINNIAS

Technically, Calibrachoa (also called million bells) is an annual in most planting zones but can return in zones 9-11 (most frost-free areas). However, I’m in zone 8A and I’ve had my Calibrachoa return several times. So don’t pluck them out when they die back just in case!

  • One of the most prolific and gorgeous bloomers of all the annuals!
  • Calibrachoa come in a variety of colors including yellow, pink, dark pink, and purple
  • Widely available at garden centers

  • Trailing flowers that are perfect for planters or containers.

Plant Calibrachoa in a planter with a potato vine and dianthus for a beautiful combination of color and texture.

SUNFLOWERS

How can anyone not love a Sunflower? They just exude happiness and summer if you ask me. There are many varieties of sunflowers, but the most common that comes to mind is the Mammoth variety that can grow more than 12 feet tall and have huge single blooms.

  • Sunflowers are best grown from seed outdoors
  • Give them plenty of room to grow – space them at least 18 inches apart and thin if necessary
  • They will follow the sun while growing
  • Sunflowers need well-drained and nutrient-rich soil
  • Suitable for Zones 2-11
  • Need at least 6-8 hours of full sun per day

Sunflowers will be a showstopper in your landscaping or garden. You can use them as cutting flowers too if you prefer though they won’t last as long as some other flowers.

PORTULACA
