Why Choose Perennials?
A garden filled with perennial plants offers the joy of seeing your landscape grow year after year with minimal effort. These beautiful and hardy plants return reliably each season, bringing bursts of color, texture, and fragrance to your outdoor space.
Whether you’re a seasoned gardener or just starting out, incorporating perennials into your garden design can create a beautiful and sustainable landscape.
What Are Perennial Plants?
Perennials differ from annual flowers and plants due to the fact that annuals have to be planted each season. Perennial plants are those that live for more than two years, returning each season from their roots. Unlike annuals, which complete their life cycle in a single year, perennials offer the benefit of longevity. They come in a wide range of sizes, shapes, colors, and bloom times, making it easy to find the perfect ones for your garden’s specific needs.
Benefits of Perennial Plants
There are so many benefits to perennial plants!
- Low Maintenance: Perennials require little care. Once they are planted, they should come back each year, which saves you time and effort in your garden spaces each season.
- Cost-Effective: While buying a perennial the first time may be an investment and higher in cost than annual plants, the fact that they live longer balances that out.
- Continuous Bloom: With careful planning, you can create a garden that has beautiful blooms from early spring to late fall with different perennial flowers and plants.
- Attracts Pollinators: Perennial flowers are often rich in nectar. This means they will attract bees, butterflies, and other pollinators.
- Erosion Control: Their deep, established root systems help prevent soil erosion, making them ideal for slopes and areas prone to runoff.
Short-lived Perennial vs. Long-lived Perennial
Short-lived perennials typically live 3 to 5 years before they start to die out, while long-lived perennials can live for 10 years or longer.
USDA Hardiness Zone and Why It’s Important
Before choosing and planting any of the examples of perennial plants below, it’s most important to understand your USDA Hardiness Zone so your collection of perennials will not only survive but flourish!
The USDA Hardiness Zone is a significant factor to consider when planting perennials (or any plants, for that matter) because it helps you determine which plants are most likely to thrive in your specific climate conditions. Here are several reasons why the USDA Hardiness Zone is important to consider.
1. Climate Suitability:
Different plants thrive in specific environmental conditions, including temperature ranges, average rainfall, and length of growing seasons. The USDA Hardiness Zone map divides the United States into zones based on the average annual minimum winter temperature.
- Each zone represents a 10-degree Fahrenheit range, with Zone 1 being the coldest (with temperatures below -50°F) and Zone 13 being the warmest (with temperatures above 60°F).
- Knowing your zone helps you choose plants that are best adapted to the typical conditions in your area.
2. Plant Survival:
Plants that are well-suited to your Hardiness Zone are more likely to survive and thrive in your garden. Here’s why:
- Winter Hardiness: Perennials that are not winter-hardy for your zone may struggle to survive the cold temperatures, leading to frost damage or death.
- Heat Tolerance: In warmer zones, heat-tolerant perennials are able to withstand high temperatures during the growing season without wilting or suffering heat stress.
3. Plant Selection:
By knowing your Hardiness Zone, you can narrow down your plant choices to those that are most likely to succeed in your area. This can save you time, money, and frustration by avoiding plants that are not suited to your climate.
- Choosing the Right Plants: Different perennials have different cold and heat tolerances. For example, a Zone 4 perennial may not survive the warmer temperatures of Zone 9, and vice versa.
- Avoiding Risk: Planting perennials outside of their recommended Hardiness Zone is risky. While some plants may survive for a season or two, they are more susceptible to stress, disease, and pest problems.
4. Timing of Planting:
The Hardiness Zone also guides the timing of planting. It indicates the average date of the last frost in spring and the first frost in fall, which helps you plan when to plant your perennials.
- Early Planting: If you live in a Zone with early last frost dates, you can start planting perennials earlier in the spring, taking advantage of the longer growing season.
- Late Planting: In Zones with late first frost dates, you have a longer window for planting in the fall, allowing perennials to establish their roots before winter.
5. Garden Success:
Ultimately, using the USDA Hardiness Zone map as a guide for planting perennials increases your chances of garden success. It sets the foundation for a healthy, thriving garden by ensuring your plants are well-suited to your local climate conditions.
How to Determine Your USDA Hardiness Zone:
- Visit the USDA Website: The USDA provides an interactive map on its website where you can enter your zip code to find your Hardiness Zone.
- Consult Gardening Resources: Many gardening books, nurseries, and online plant retailers also include Hardiness Zone information for their plant listings.
As you can see, understanding the USDA Hardiness Zones is very important since it’s a valuable tool for gardeners, especially when it comes to planting perennials. By selecting plants suitable to your Zone, you create an environment where your perennials can thrive and bloom, providing years of beauty and enjoyment in your garden.

Tips for Growing Perennials Successfully
- Soil Preparation: Most perennials thrive in well-drained soil rich in organic matter. Mix up the soil with compost before planting to improve fertility and drainage. Visit Grow Organic to understand more about compost.
- Planting Depth: Follow specific planting instructions for each perennial, ensuring they are placed at the correct depth for optimal growth.
- Watering: While established perennials are generally low-maintenance, regular watering is crucial during the first season of a perennial’s life. Once established, water according to the plant’s specific needs.
- Mulching: Apply a layer of organic mulch around perennials to conserve moisture, suppress weeds, and insulate roots against changing temperatures.
- Deadheading: Remove dried-out or dead flower buds to encourage continuous blooming and prevent self-seeding, especially for species prone to spreading aggressively. If certain plants end up spreading, they can be difficult to get rid of!
