Probably one of the most asked questions by any gardener would be the choices between annuals vs. perennials for landscaping. Here at Riverview Tree and Landscaping, so many of our customers call and ask for advice about how they are different and which ones to plant in their gardens. Understanding annuals vs. perennials is very key to finalizing a beautiful and healthy outdoor space that suits your needs and style.

Annuals vs. perennials flowering plants are two different classes, each with its characteristics and advantages. While annual plants complete their life cycle in one growing season, perennials come back year after year. Now, let’s go deeper into the differences of annuals versus perennials so that you can make an informed decision whenever the options are right for your garden.

What Are Annual Plants?

Annual plants are plants that grow, bloom, produce seeds, and die in one growing season. This means that all energy is given to flower and seed production quickly, and they, therefore, form vivacious and long-flowering blooms. Examples of annual flowers include petunias, marigolds, zinnias, and impatiens.

Advantages of Annuals:

Longer blooming time: Most annuals bloom throughout the growing season, offering constant color from spring into fall.

Fast growth and quick blooming: It grows fast and blooms soon enough after it is planted, immediately brightening up your garden with color and beauty. Design flexibility: Since you replant annuals every year, you can easily and at will do so, thereby changing your garden’s look and color scheme from season to season.

Filling in the gaps: Annuals are good at adding pops of color between perennials or filling bare spots in gardens.

Cons of Annuals:

Needs to be replanted yearly: Since annuals complete their life cycle in one season, this means you will have to purchase and replant new ones yearly.

Higher maintenance: As a rule, annuals require more frequent watering and fertilizing to keep them in bloom all season.

Can be long-term costly: All that buying of new plants year after year can really add up.

What Are Perennial Plants?

Perennial plants want to live for more than two years and come back in the spring from their rootstock. These plants basically put the majority of their energy into developing strong root systems that help them live through the winter and regrow every year. Examples of perennials are daylilies, coneflowers, and black-eyed Susans.

Pros of Perennials:

They can be a long-term investment because once they are established, they will come back every year, saving you time and money in the long run.

Less maintenance: Except for the initial time needed for planting and subsequent establishment, perennials generally require less maintenance than annuals.

Seasonal interest change: Many perennials change interest throughout the year, such as spring blooming, summer foliage, or fall colors.

Improved soil structure: Deep roots of the perennial help to enhance the quality of soil over time.

Cons of Perennials:

More limited time of bloom: Most perennials have only one blooming period and do not flower as continuously as annuals do.

Slower to establish: It can take a year or two before perennials reach their mature size and full blooming potential.

Less flexibility: Because perennials come back year after year, it can be harder to change your garden’s design without moving or removing plants.

How to Decide Between Annuals vs. Perennials

The decision of annuals vs. perennials for your garden will depend on:

Time and effort: If you enjoy planting new flowers every year and you do not mind the extra work involved, then annuals may be the way to go. Otherwise, perennials could be a good option if you want less maintenance work.

Budget: While perennials may turn out to be more expensive at first glance, annuals often need replanting every year, which adds up in price. Perennials can cost a little more upfront but will save money over time.

Garden goals: If you want constant, vibrant color throughout the growing season, annuals are an excellent option. If you’re looking for a more naturalistic, evolving garden that changes with the seasons, perennials might be better suited.

Climate: Some plants that are technically operated as annuals in colder regions are perennials. Consider your local climate when making your selection.

Combining Annuals and Perennials

We often recommend incorporating both annual and perennial planting into your design so you get the benefits of both worlds. This would involve the following structural elements of making perennials in your garden, there when the seasons change.

Add mixtures of annuals in pots or hanging baskets to supplement perennial beds and tweak flexibility into your design.
Play with the mix to get that perfect combination of annuals and perennials for your garden and your lifestyle.
