Annuals or Perennials? What To Pick For Your Garden


Plant selection can be tricky. Among the many decisions you’ll face, one of the most fundamental is whether to plant annuals or perennials. Each type of plant offers its own set of advantages and considerations, making the choice between them key in determining your garden’s overall look, feel, and maintenance. In these slides, we’ll explore the differences between annuals and perennials.



Within a single growing season, annuals will undergo the full life cycle, from seed to flower to seed. They germinate, grow, flower, set seed, and die in one year. Conversely, perennials live for over two years, often flowering for many years. Many die back to the ground in winter and regrow from the same roots in spring.

Blooming Period


Because they have more extended blooming periods than perennials, annuals can bring continuous color and interest to the garden throughout the growing season. While perennials may have shorter blossoming periods, they can be strategically chosen to give a succession of blooms from spring to fall.

Planting Effort

Annuals have to be replanted every year as they complete their life cycle in one season. You’ll need to prepare the soil, plant the seeds, and tend to them throughout the growing season. Once established, perennials need less effort as they return year after year. Planting perennials involves preparing the soil well and providing adequate water and nutrients during their establishment period.



Initially, perennials may seem more expensive than annuals, as they are typically sold in larger pots and are more established. However, perennials, over time, provide better value as they return the following year, unlike annuals that need repurchasing.

Generally, annuals require more maintenance than perennials—from regular watering and fertilizing to deadheading and more to encourage continuous blooming. Once established, perennials are fine with less commitment, although they may benefit from occasional division and fertilization.

Seasonal Changes


One advantage of annuals is the opportunity to change your garden’s look each year by trying different plant varieties, colors, and combinations. While they give a consistent garden appearance, perennials can be strategically chosen for their bloom times and colors to create a cohesive garden design.

Winter Care


In colder climates, perennials may need special care to survive the winter. This may include mulching to protect the roots or, in some cases, bringing potted perennials indoors. As seasonal plants, annuals are replanted during spring, so winter care is not a concern.

Growth Rate

Annuals grow and bloom quickly, providing immediate color and impact in the garden. Because of this, they are ideal for filling in gaps or creating a vibrant display. Perennials, while they may take a year or more to establish fully, bring long-term stability and structure to the garden.



Because annuals come in various colors, sizes, and textures, they can easily add variety to your garden. They can create bold, eye-catching displays or soft, romantic borders. With more limited options, perennials offer long-term consistency and can be selected for their specific bloom times and growth habits.

Wildlife Attraction

Both annuals and perennials can attract pollinators and beneficial insects to the garden. The continuous blossoming periods of annuals can supply pollinators with a steady food source throughout the growing season. At the same time, perennials provide a stable habitat for wildlife and can attract a wider variety of species.

Environmental Impact

After establishing, perennials generally need less water and fertilizer than annuals. This makes them more environmentally friendly and sustainable in the long run. Even though annuals require more resources, they can still be grown sustainably with proper care and watering practices.

Soil Health


The deep roots of perennials help to aerate the soil and improve drainage, improving soil structure and health over time. Although annuals are guilty of depleting soil nutrients more quickly, they can still contribute by adding organic matter when composted at the end of the season.

Space Consideration

If you have limited space, annuals can be a better choice as they can be easily rotated to bring different looks each year. You can also grow them in containers or hanging baskets to add color to small spaces. While perennials offer longer stability, they may require more room and planning to accommodate their growth habits.

Garden Design


Consider your garden’s overall design and theme when choosing between annuals and perennials. Annuals offer flexibility for changing themes yearly, while perennials provide a more consistent backdrop. Mixing annuals and perennials can create a lovely and ever-changing garden space.

Personal Preference

The choice between annuals and perennials could depend on whatever you like or fancy. Is it something you saw on TV and want to see in your garden? Is a masterpiece in your friend’s garden something you want badly, too? If you are willing to invest the time and effort needed to maintain the plant, go for it.
