The Top 6 Best Annuals For Sun - Our Subjective List

There are several varieties of begonias. However here, we're talking about"wax begonias," called this because of their shiny leaves. They are often called bedding begonias because unlike other varieties, this variety is the best choice for flower beds because of their growing habits.

They grow short - 6-8 inches tall - and in mounded form. If you plant them in large groups, they will often grow together in a big mound of colorful flowers.

Wax begonias come with green or deep red foliage, which will give your garden that tropical vibe! Flowers tend to be small but there are a lot of them on each plant. They come in red, pink or white. Large groupings typically look best planted with one color and style per group - a planting technique which gives the most impact.

There are a wide variety of begonias out there, some looking quite different from one another. Some look so different you'll wonder if they are begonias at all. One is the "Dragon Wing Begonia." This variety does best in filtered light, and does great in pots or hanging baskets on a porch. So if you're looking for a showy plant for your porch, choose this.

bed of geraniums

Geraniums are one of the best annuals for sun because they thrive in hot sunny weather and will tolerate drought fairly well. Large beautiful blooms will be there from early summer until frost. Some colors are so vibrant they seem to glow!

In warmer climates they would be considered a perennial but in most areas they are an annual. They won't survive a frost, so if you live in an area that get's cold weather, you'll need to treat them as an annual.

You can also overwinter geraniums by digging them up and bringing them in during the cold winter months and putting them back out in spring.

For continuous blooms it helps to "dead head" the flowers. Just pinch off the spent blooms where they meet the stems. This will send energy back to the plant and produce new blooms quicker. However, if you don't have time to deadhead, it's OK. They will still re-bloom, although it might take a little longer and the dead blooms will not be all that attractive.

When you're in your local garden center, look for "Zonal Geraniums" (pictured), which are a particular favorite of ours. These are different than "seed geraniums" which are propogated from seeds as the name implies.

Seed geranius grow smaller with more numerous but much smaller flowers. Zonal geraniums are propogated from cuttings and have much larger blooms that are bigger and bolder than the seed variety . Zonal geranium flowers are just spectacular!

You can use geraniums as a bedding plant in groups, or a border or accent plant. We know of pro designed gardens where zonal geraniums are used in large groups. This makes for a spectacular garden but the choice is up to you.

Petunias are another great annual for use in sun gardens. They are super easy to grow and require very little care. Plus they put on a spectaular show and as a bonus - are very fragrent.

Petunias tend to droop and trail downward, making them an excellent choice for hanging baskets and pots but you can also use them in gardens.

These plants come an a wide variety of colors, from various shades of purple, to white, pink, and varigated colors as well. Each year it seems more and more varities of flower colors are cultivated and brought to market. We love browsing the petunia isles to find out they new plants for the year. There are, literally, hundreds of different varieties.

Like geraniums above, petunias need dead heading for more frequent blooms. Just pinch off the spent flowers where they meet the stems.

Petunnias have a trumpet shaped flower that tends to attract humingbirds as well, which is an added benefit if you plant them in hanging pots or baskets on a deck or patio.

A favorite variety of petunia we like  is called the "wave petunia." We use these as a ground cover in gardens because they spread outwards in numerous stems, each stem producing many blooms. Pick up a pot of wave pentunias and compare them to the regular ones and you'll see the difference.

Blue Agoratum

A common plant in our growing zone, blue agoratum is often used in garden borders and should be considered in a group planting. It's rarely used as a stand alone plant.

It's flower color is a light sky blue to purple-ish blue, which is very uncommon in the flower world and therefore, makes it stand out.

Although it comes in other colors, we've not found those to be widely available. Hence, the word "blue" in the name.

It grows 1-2 feet and in mounds, with the blue flowers very numerous over the entire plant. This makes the foliage an afterthought and not part of the look of the plant. We love the flowers themselves.

Plant this in full sun only, especially in northern climates. In the south, which tends to be hotter, a partial shade garden would work. We've tried it in partial shade gardens here in our planting zone of 6 and it has never done well.

The good news is blue agoratum needs no care at all after planting, which makes it an excellent choice.

Flowering Vinca

Vinca is a gorgeous annual that has a similar flower to impatiens. However, unlike impatiens, which like shade, vinca is definately a sun plant. If you try a garden that's in parial shade, they may survive but be prepared for less blooming.

We are not talking about vinca vine which is, as the same says, a ground cover vine. Don't mistake the 2. We're talking about the summer flowering annual, here, which is totally different.

The Vinca flowers are unique because some have different colored centers, which makes them stand out as vinca. See the image above for an example of this flower.

Vinca is also popular with professionals because, like begonias, it's often used in large groupings, which makes for a massive showing of color.

Vinca is another plant that needs no care at all after planting. Once in the ground, if conditions are good, it will thrive.

When talking about the best annuals for sun, we couldn't forget the much loved pansy.

Here in our growing zone, pansies are considered a fall annual. They are planted in the fall, replacing the summer annuals that will die at the first frost. You see, pansies don't die when cold sets in. They actually overwinter - even in the snow - and rebloom in the spring, or during the winter if temperatures are above degrees.

The reason they do well in the fall and spring is because pansies do not like summer heat. They do like full sun however, as long as the temperatures stay moderate. Once hot weather arrives, they get leggy and straggly.

This is why in the fall you'll often see professionals replacing summer full sun annuals with pansies. Then, come spring, they bloom early and continue until the weather gets hot. So, in May or June they're replaced by summer annuals. And the cycle continues year after year.

Fall pansies - Sept. through May.
Summer Annuals - May through Sept.

Pansies come in a wide variety of colors. Some flowers are multicolored, with the dark colors resembling faces. This is why the pansy plant has been known as the flower with the faces.
