Peonies and lilies can be planted together, and when done right, they can create a stunning garden display filled with complementary colors and varied textures.
But can you plant peonies and lilies together without causing issues for either plant?
The answer is yes, you can plant peonies and lilies together as long as you consider their specific growing needs and timings to ensure both thrive side by side.
In this post, we’ll explore whether you can plant peonies and lilies together, the benefits of doing so, and some important tips to help you create a flourishing garden bed with these two beloved perennials.
Why You Can Plant Peonies and Lilies Together
Planting peonies and lilies together is a great idea for many gardeners.
1. Similar Growing Conditions
Both peonies and lilies prefer well-drained soil and a sunny location with at least six hours of direct sunlight each day.
This similarity in basic growing conditions makes it easy to accommodate both plants in the same bed without compromising their health.
2. Complementary Bloom Times
Peonies generally bloom in late spring to early summer, filling your garden with large, fragrant flowers.
Lilies typically bloom later, from mid to late summer.
This staggered blooming means that planting peonies and lilies together gives your garden continuous color for a longer period.
3. Visual Appeal and Contrast
The lush, rounded blossoms of peonies contrast beautifully with the tall, elegant stems and trumpet-shaped flowers of lilies.
This combination enhances the overall aesthetic of your garden and creates an interesting texture contrast.
So, planting peonies and lilies together isn’t just practical — it’s a visual win as well.
Growing Requirements When You Plant Peonies and Lilies Together
To ensure your peonies and lilies thrive when planted together, you need to pay attention to their specific needs in terms of soil, water, and care.
1. Soil and Drainage
Both peonies and lilies dislike soggy soil.
Peonies need deeply fertile, well-drained soil rich in organic matter to develop strong roots and abundant blooms.
Lilies also require well-drained soil but can tolerate slightly sandier soils.
When planting peonies and lilies together, improve your garden bed with compost or well-aged manure to ensure both enjoy fertile, moisture-balanced soil.
2. Spacing and Depth
Peonies need space to grow since their mature width can be up to 3-4 feet depending on the variety.
On the other hand, lilies require enough space to prevent overcrowding of their bulbs and good airflow to prevent fungal diseases.
When planting peonies and lilies together, make sure to space them adequately, usually about 18-24 inches apart for each plant type, to allow for healthy growth and airflow.
Also, plant lilies deeper (about 6 inches for most types) so their bulbs are well protected, while peonies should be planted with their eyes (buds) just about 1-2 inches below the soil surface.
3. Watering Needs
While peonies prefer consistent moisture, they do not like sitting in waterlogged soil.
Lilies prefer moderate watering, especially during their growing and blooming phases.
When you plant peonies and lilies together, aim for consistent but moderate watering, where the soil stays moist but not soggy.
Mulching in your bed will help retain moisture and reduce weeds, benefiting both plants.
4. Fertilizing
Peonies benefit from feeding with a balanced fertilizer in early spring and again after blooming.
Lilies prefer the same but especially appreciate a high-phosphorus fertilizer when buds start appearing.
Applying a slow-release, balanced fertilizer as you plant your peonies and lilies together will give them the nutrients they need throughout the growing season.
Potential Challenges When Planting Peonies and Lilies Together
While you can plant peonies and lilies together, a few challenges are worth keeping in mind to avoid problems.
1. Different Growth Habits
Peonies are bushy and spread out with large foliage, while lilies grow vertically with tall, slender stems.
Make sure to plant lilies where they won’t be overshadowed by the larger peony foliage, so both plants get adequate sunlight, especially lilies, which need full light to bloom well.
2. Disease and Pest Considerations
Both peonies and lilies can be susceptible to fungal diseases like botrytis blight, especially in humid climates.
When planting peonies and lilies together, ensure good air circulation around the plants to reduce humidity buildup.
Keep an eye out for pests like aphids on peonies and lily beetles on lilies—the mix of plants might attract more attention, so regular monitoring helps.
3. Timing for Planting
If you’re planting from bulbs (lilies) and bare-root plants or divisions (peonies), timing differs slightly.
Peonies are best planted in the fall or very early spring, while lily bulbs are often planted in spring after the danger of frost has passed.
When planting peonies and lilies together, plan your garden layout early and plant accordingly to give each plant the best chance for establishment.
Tips for Successfully Planting Peonies and Lilies Together
Now that you know you can plant peonies and lilies together, here are some tips to ensure your combined planting looks fantastic and remains healthy.
1. Choose Compatible Varieties
Not all lilies and peonies are created equal.
Try pairing taller and sturdier varieties of lilies like Asiatic or Oriental lilies with large-flowered herbaceous peonies for balance.
Avoid overly tall lilies that might overshadow smaller peony varieties or very late-blooming lilies that won’t add to the bloom sequence.
2. Use Mulch to Maintain Soil Moisture and Suppress Weeds
Apply a 2-3 inch layer of organic mulch after planting your peonies and lilies together.
Mulching not only keeps the soil moist but also reduces weeds and protects bulbs and roots from extreme temperatures.
3. Support Taller Lilies If Needed
Some lilies grow tall and can flop over, especially with heavy rain.
Prepare to stake taller lilies when you plant them together with peonies, which naturally stay sturdy.
4. Deadhead and Prune for Continuous Beauty
Deadhead spent peony flowers to encourage bushes to stay neat and direct energy to root development.
Similarly, remove fading lily blossoms to encourage bulb health and reduce disease risk.
5. Plan for Future Growth
Remember that peonies will slowly increase in size over the years, while lilies can multiply by producing new bulbs.
Space your plantings with enough room to divide and transplant later without disturbing the other plants when you plant peonies and lilies together.
So, Can You Plant Peonies and Lilies Together?
Yes, you absolutely can plant peonies and lilies together, and doing so can lead to a beautiful and dynamic garden that highlights the best features of both plants.
The key to success when you plant peonies and lilies together lies in understanding their shared and distinct growing needs—from light, soil, and water to planting depth and timing.
By giving both plants the conditions they need and considering spacing and bloom time, you will enjoy a long-lasting floral display with continuous interest.
The challenges of planting peonies and lilies together are manageable with good garden planning, proper care, and vigilance against pests and diseases.
So, whether you’re looking for the lush, romantic appeal of peonies alongside the elegant, vertical grace of lilies, planting these two together can be a winning choice for your garden.
Happy gardening!
