- Companionship: Group plants with similar requirements and consider beneficial partnerships.
- Diversity: Plant a variety of species to attract wildlife and reduce pest and disease pressure.
Perennial Plant FAQ
Annuals complete their entire life cycle in a single growing season. They germinate, grow, flower, produce seeds, and die all within one year. Examples include petunias, marigolds, and zinnias.
Perennials live for more than two years. They typically die back to the ground in winter but return from their roots the following spring. Examples include roses, lavender, and hostas.
The lifespan of a perennial can vary greatly. While the term "perennial" implies a plant that lives for more than two years, the reality is quite diverse.
- Short-lived perennials: These might last for only a few years.
- Long-lived perennials: Some can thrive for decades, even centuries.
Factors like climate, soil conditions, and proper care can significantly impact a perennial's lifespan.
Here are some perennials known for their longevity:
Classic Choices:
- Peonies: Renowned for their long life and stunning blooms.
- Irises: Offer a variety of colors and can last for many years.
- Daylilies: Incredibly adaptable and long-lived.
- Hostas: Known for their shade tolerance and longevity.
Underrated Gems:
- Oriental poppies: Dramatic blooms and can live for decades.
- Catmint: Resilient and returns year after year.
- Sedum: Offers drought tolerance and long-lasting beauty.
- Coreopsis: Provides continuous bloom and can be long-lived.
Remember, proper care and suitable growing conditions are essential for maximizing the lifespan of your perennials.
Understanding Plant Needs
Just like people, plants have specific needs that must be met to thrive. Selecting plants that are well-suited to your garden's conditions is key to ensuring their success and minimizing maintenance. One of the most crucial factors to consider is soil drainage.
Soil Drainage: A Key Consideration
Most plants prefer moist, well-drained soil. If your soil drainage is less than ideal, either too slow or too fast, you can improve it to some extent by adding organic matter. However, it's often more efficient to start with plants that are naturally suited to your existing soil conditions.
Plants for Wet Soils
If your soil tends to stay damp most of the time, choose plants that can tolerate abundant moisture.
Plants for Dry Soils
For light or sandy soils that dry out quickly, drought-tolerant plants are the best choice.
The Good News: There's a Plant for Every Soil
Fortunately, there are plants that can thrive in both wet and dry conditions. By carefully considering your soil type and selecting plants that are well-suited to its characteristics, you can create a beautiful and low-maintenance garden.
Climate & Growing Zone:
- Research your growing zone: This will determine which plants are best suited to your local climate.
- Consider temperature extremes: Are summers hot and dry, or winters cold and snowy?
- Check for specific plant requirements: Some plants need specific temperature ranges to thrive.
Landscaping Goals:
- Define your purpose: Do you want to create a colorful border, a low-maintenance ground cover, or a pollinator garden?
- Consider the overall style: Choose plants that complement your garden's aesthetic (e.g., cottage garden, modern, or native plants).
- Think about size and spacing: Ensure plants will fit the available space and will not outgrow their area.
Useful, Pretty, Low Maintenance:
- Balance aesthetics and practicality: Consider plants that are both visually appealing and functional (e.g., pollinator-friendly, edible, or drought-tolerant).
- Prioritize low maintenance: If you are short on time, choose plants that require minimal pruning, watering, or fertilization.
- Research plant characteristics: Consider factors like bloom time, foliage color, and growth habit.
Soil Type:
- Test your soil: Determine its pH (acidic, neutral, or alkaline) and texture (sandy, loamy, or clay).
- Choose plants accordingly: Some plants prefer acidic soil, while others thrive in alkaline conditions. Texture also affects moisture retention and drainage.
Weather Patterns:
- Consider rainfall and drought: Choose plants that can tolerate your local precipitation levels.
- Think about wind and humidity: Some plants are more susceptible to wind damage or fungal diseases in humid environments.
Local Extension Office:
- Seek expert advice: Contact your local extension office for specific recommendations based on your region.
- Learn about local pests and diseases: They can provide information on common problems and preventive measures.
- Get advice on soil testing and plant care: Extension agents can offer guidance on soil amendments and proper care practices.
By carefully considering these factors, you can select perennial plants that are not only beautiful but also well-suited to your garden's unique conditions.
The best times to plant perennials are spring and fall.
Fall Planting - Some say perennials can be planted anytime until the ground freezes. We recommend planting at least 30 days before the first hard frost, to allow new feeder roots to get established before the ground freezes.
Fall is an excellent time to plant perennials. The warm soil conditions encourage robust root development, providing plants with a strong foundation for vigorous growth the following spring. This is especially beneficial for spring-blooming perennials, including those purchased as bare roots. By giving these plants, a head starts in the fall, you can expect fuller blooms and healthier plants come springtime.
Spring blooming perennials, especially bare root, are best planted early in the fall. Fall planting, while the soil is still warm, allows roots time to establish. Thus, plants emerge with well-established roots, providing a stronger start next spring.
Remember, it's essential to consider your local climate, frost dates and each plant's needs for the best outcomes.
Spring Planting
- Warmer soil temperatures
- Longer days for sunlight
- Ample rainfall in many regions
Fall Planting
- Cooler temperatures reduce plant stress
- Allows roots to establish before winter
- Often better for plant establishment overall
However, it's important to consider your specific climate. Some regions might have more favorable planting times than others. Always check local weather conditions before planting.
Spring Planting
- Pros:
- Immediate visual gratification as plants begin to grow quickly.
- Ideal for impatient gardeners.
- Good for annuals and vegetables.
- Cons:
- Competition with established plants for resources.
- Potential for transplant shock if weather is too hot or dry.
Fall Planting
- Pros:
- Plants have time to establish roots before the busy growing season.
- Often results in healthier, more vigorous plants the following year.
- Less competition from established plants.
- Cons:
- Requires planning ahead.
- Risk of frost damage, although less likely in milder climates.
Generally, fall planting is often considered the better option for perennials. It allows them to establish a strong root system before the demands of the growing season. However, the best time to plant will ultimately depend on your specific climate and the type of perennials you're planting.
Knowing the average date of the last spring frost in your area is crucial for planning your garden and avoiding damage to frost-sensitive plants. Know your hardiness zone’s first and last frost date. These are recommended dates you should consider before planting in the spring or fall. If planting too early you could be at risk of a late freeze which would kill tender plants in the spring. Avoid these freeze temperatures that will affect your plant's early growth.
There are different “levels” of frost. The Almanac splits them up into three sections:
- A light freeze occurs between 29 to 32 degrees Fahrenheit.
- A moderate freeze is defined as temperatures within the range of 25 to 28 degrees Fahrenheit.
- A hard frost is when temperatures fall below 25 degrees Fahrenheit.
Some plants, usually those native to colder climates, will fare well with a light freeze. However, it can also easily kill more delicate plants. When in doubt, wait it out. Damage to plants happens faster, and is more severe, as the temperature falls. Colder weather often includes wind and precipitation. These can contribute greatly to frost damage, especially when the plant is already in a weakened state.
Freeze warnings are issued in fall as the first frost and freeze conditions begin to appear and can occur in early spring as well. Use the information below to find the estimated dates for first frost and last frost in your USDA zone.

One of the most important considerations in choosing perennial plants for any garden is hardiness zones. The U.S. Department of Agriculture developed and maintains a USDA Plant Hardiness Zone Map that assigns a numerical value and color to every area of the United States. Plant pages provide the generally recommended Hardiness Zones for each plant.
A plant hardiness zone is a geographical area defined by its average minimum winter temperature. This information helps gardeners and growers determine which plants are most likely to survive the winter in a particular location. The zone information provided on this website is strictly a guideline.
Important to Note: Zone information is a general guideline. Local conditions like snow cover, humidity, and microclimates can significantly impact a plant's survival.
The zone map used on this website is based on the 1990 USDA Plant Hardiness Zone Map. This map is the foundation for the plant information provided.
Zones listed in parentheses ( ) indicate marginal hardiness. A plant in a parenthesized zone might survive with extra protection, but it's not guaranteed to thrive. For example, a plant listed as zone (4)5-9 can potentially survive in zone 4 with careful protection, but it will likely flourish in zones 5 through 9.
Zone 3: -40°F to -30°F
- Most plants native to the U.S. are found within Zones 3 to 10; the toughest of plants can withstand all these zones. Zone 3 plants can withstand cold temperatures of -40°F to -30°F. The upper Midwest states and some northeast states hold most of Zone 3, such as northern parts of Montana, North Dakota, Minnesota, Wisconsin, Wyoming, New York, and Maine.
- When to Plant: Mid-May
Zone 4: -30°F to -20°F
- Zone 4 plants can withstand minimum chill temperatures from -30°F to -20°F. You can find this zone in Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, and northern areas of Eastern states such as New York, Vermont, New Hampshire, and Maine.
- When to Plant: Mid-May
Zone 5: -20°F to -10°F
- This zone is another common one for the Midwest and Northeastern states, where humidity stays high during the summers, and winters can reach as low as -20°F to -10°F. You can find Zone 5 in Colorado, Utah, Nebraska, Iowa, Wisconsin, Illinois, Indiana, Michigan, Pennsylvania, and New York.
- When to Plant: Mid-April
Zone 6: -10°F to 0°F
- It is the middle of the road for Zone 6. You can find this zone in Pacific Northwest states, such as Washington and Oregon, and stretching over the middle of the U.S. in states such as Kansas, Missouri, Kentucky, Illinois, New Mexico, and all the way through Ohio. Plants in this zone can withstand temperatures of -10°F to 0°F.
- When to Plant: Mid-April
Zone 7: 0°F to 10°F
- Winters only occasionally hit the negatives in this zone. Plants in Zone 7 can handle temperatures of 0°F to 10°F. You can find this zone in some parts of Washington and Oregon and down through upper Texas, Oklahoma, and most of the way through Virginia and North Carolina.
- When to Plant: Mid-April
Zone 8: 10°F to 20°F
- Things are starting to heat up in Zone 8. In this zone, native plants love the warmth. Also, plants have a longer growing season in Zone 8. You can find this zone in part of the West Coast and most of the South, such as Texas, Louisiana, Mississippi, Alabama, Georgia, and the Carolinas, and along the coast of Virginia.
- When to Plant: Mid-March
Zone 9: 20°F to 30°F

- When to Plant: Mid-January
The ideal spacing for perennials depends on their mature size.
Here's a general guideline:
- Small perennials (under 1 foot): 6-12 inches apart
- Medium perennials (1-2 feet): 12-18 inches apart
- Tall perennials (over 2 feet): 18-36 inches apart
Factors to Consider:
- Mature size: Always check the plant tag or do online research to determine the plant's full-grown dimensions.
- Growth habit: Some plants spread more than others. Consider their growth pattern when spacing.
- Desired effect: If you want a fuller look faster, you can plant slightly closer initially, but be prepared to thin them out later.
- Soil conditions: Richer soil can promote faster growth, so you might need to adjust spacing accordingly.
Additional Tips:
- Visualize the mature plants: Imagine how big each plant will be when fully grown and space accordingly.
- Consider companion planting: Some plants complement each other and can be planted closer together.
- Allow for air circulation: Proper spacing helps prevent diseases by allowing good airflow.
Generally, perennials need about an inch of water per week. This can come from rain or supplemental watering.
Key factors affecting watering frequency:
- Climate: Hot, dry climates require more frequent watering.
- Soil type: Sandy soil drains quickly, needing more frequent watering than clay soil.
- Plant type: Some perennials are more drought-tolerant than others.
- Plant age: Newly planted perennials need more frequent watering to establish roots.
Watering tips:
- Deep watering: Instead of frequent shallow watering, aim for deep, infrequent watering to encourage deep root growth.
- Mulching: Apply a layer of mulch around your perennials to help retain soil moisture and suppress weeds.
- Check soil moisture: Stick your finger about an inch into the soil. If it's dry, it's time to water.
- Monitor plant health: Watch for signs of underwatering (wilting, yellowing leaves) or overwatering (yellowing leaves, root rot).
Remember, it's better to underwater than overwater. Perennials often tolerate dry spells better than soggy roots.
Both fertilizer and compost can benefit your perennials, but the approach depends on your soil's condition and the specific needs of your plants.
Compost: A Natural Boost
- Benefits: Compost improves soil structure, retains moisture, and provides essential nutrients.
It's a gentle and long-lasting way to enhance your garden.
- Application: Apply a 2-inch layer of compost around your perennials in spring. You can also incorporate it into the soil before planting.
Fertilizer: Targeted Nutrition
- Benefits: Fertilizer provides specific nutrients to address deficiencies. However, it's easy to over-fertilize, which can harm your plants.
- Application: Use a balanced fertilizer (like 10-10-10) sparingly, typically once or twice a year in early spring. Avoid fertilizing late in the season, as it can encourage new growth that won't harden off before winter.
Important Considerations:
- Soil testing: Get your soil tested to determine nutrient levels before applying fertilizer.
- Plant needs: Some perennials are heavy feeders (like peonies), while others prefer less-fertile soil.
- Organic vs. synthetic: Choose organic or synthetic fertilizers based on your preferences and garden philosophy.
Generally, healthy soil enriched with compost is sufficient for most perennials. Fertilizer should be used as a supplement if needed.
