25 Full Sun Annuals to Boost Your Home’s Curb Appeal

Full sun annuals are wonderful additions to your yard or landscape if you’re not sure what would look best as they die off after a year. There are dozens of different full sun annuals available, and they come in a host of bright colors, sizes, and shapes to add interest and texture to your yard. You can easily plant them in containers, raised planter boxes, along walkways, or in traditional flower beds. If you mix and match your full sun perennials, you can get a colorful show that starts in the early spring months and goes well into fall. However, you have to know which ones to plant.

I want you to have success with your full sun perennials and boost your home’s curb appeal all season long, and this is why I created this extensive list. I’ll have full sun perennials in all shapes, sizes, and colors that you can look at and decide whether or not they’re something you want to try. Most of them are easy to grow and maintain, and a lot of them like the same growing conditions. This makes it easy to care for them all at the same time and keep them healthy until they die back in the fall months.

1. Sweet Peas

The first full sun annual on the list is the Sweet Pea, and this plant is native to the eastern Mediterranean region. They come in different hues of purple, pink, and red, and they produce a very sweet fragrance when they start to bloom. Depending on the cultivare you choose, they can get up to nine-feet high. There are also species that will only get up to around 20-inches high at full maturity, and these are excellent for potted plants. The deep green foliage helps the flowers stand out even more. They grow best in zones 8 to 10 in a rich but well-drained soil and a lot of sun.

2. Marigolds

Marigolds are, hands down, one of the easiest full sun annuals to grow. They can grow well in zones 2 go 11 as long as you put them in a well-drained soil with plenty of sunshine. They don’t tolerate cold well, and the seeds start to germinate around the middle of April. You should start to see flowers very quickly, and they can grow between six-inches and two-feet tall, depending on the cultivar. You’ll get green foliage that is very thick with these plants, and they have a rounded flower head that is a bright pop of color that comes in yellow, red, and orange. As a bonus, this plant is excellent for pest repellent.

3. Calibrachoas

This is another very hardy full sun annual that will grow in almost any container or soil without a problem.
