24 Perennials You Should Never Plant Next To Each Other

Sharing is caring!

Gardening is a delightful pursuit, yet it can sometimes feel like a tricky puzzle. Imagine planting your favorite perennials only to discover they aren’t getting along.

Let’s unravel the mystery behind these botanical disagreements and explore 24 specific pairings you should avoid for a thriving, harmonious garden.

1. Mint And Lavender

@positivebloom

Mint is a robust herb, flourishing aggressively wherever it’s planted. Lavender, on the other hand, prefers a more restrained, calm environment. In a garden, mint’s rapid spread can overshadow lavender, depriving it of necessary nutrients.

Lavender’s preference for well-drained soil clashes with mint’s thirst for moisture. The combination can lead to poor growth for both. Ensure to plant them separately to maintain their individual beauty and health. This separation allows lavender to bask in its sunlit serenity while mint can ramble freely without interference.

2. Roses And Garlic

@positivebloom

Roses, the timeless symbols of elegance, thrive in a well-balanced environment. Garlic, while a great pest deterrent, can be too overpowering for roses. The strong scent and robust growth of garlic can disturb the delicate nature of roses.

This mismatch can lead to stunted growth or even disease. If you love both, try planting garlic at a distance where it can still ward off pests without overwhelming the roses. This arrangement allows roses to flourish without the pungent interference of garlic’s aroma.

3. Peonies And Daisies

@positivebloom

Peonies, celebrated for their lush blooms, need a particular setting to thrive. Daisies, cheerful and sun-loving, can encroach on peonies’ space with their rapid growth.

This competition over resources can restrict the peonies’ growth, leading to fewer blooms. Instead, provide each with its own space to grow and shine. By doing so, peonies can achieve their full blooming potential, and daisies can spread their sunny charm unrestrained.

4. Hostas And Ferns

@positivebloom

Hostas, with their broad, luxurious leaves, crave ample space to spread. Ferns, with their intricate fronds, also desire room to showcase their beauty.

Planting them together in a shaded area can lead to a battle for light and nutrients. This struggle often results in stunted growth for both. Separating them allows each plant to thrive in its own area, maximizing their aesthetic appeal in your garden.

5. Astilbe And Daylilies

@positivebloom

Astilbe, known for its colorful plumes, requires consistent moisture to flourish. Daylilies, rugged and sun-loving, often demand more nutrients and space to grow.

When planted side by side, they compete for water and soil nutrients, which can lead to lackluster growth. Keeping them apart ensures that astilbe can enjoy its moist environment while daylilies soak up the sun and nutrients they crave.

6. Yarrow And Delphiniums

@positivebloom

Yarrow is a hardy perennial, known for its resilience in dry, poor soils. Delphiniums, with their stunning spikes, require rich, moist conditions to thrive.

Together, they clash over soil preferences, leading to poor growth and flowering. Placing them in separate garden sections allows each to thrive under its preferred conditions, highlighting their unique beauty without competition.

7. Fennel And Coriander

@positivebloom

Fennel, with its towering structure and aromatic seeds, often dominates its surroundings. Coriander, a delicate herb, prefers a more subdued environment.

Their proximity can lead to fennel overshadowing coriander, hindering its development. It’s wise to plant them apart, ensuring that coriander can grow lush and green while fennel can stand tall without interference.

8. Lupines And Columbines

9. Thyme And Chives

@positivebloom

Thyme, a versatile herb, loves dry, well-drained conditions. Chives, with their onion-like flavor, prefer more moisture and richer soil.

Together, they conflict over environmental needs, which can result in poor growth for both. Separating them ensures that thyme stays crisp in its dry habitat while chives grow juicy in their moist environment.

10. Bleeding Hearts And Foxgloves

@positivebloom

Bleeding hearts, with their romantic arching stems, thrive in shaded, moist areas. Foxgloves, tall and majestic, prefer similar conditions but demand more space.

Their shared preferences can lead to competition for nutrients and space, stunting their growth. By giving each plant its own section, you allow them to grow to their full potential, adding elegance and charm to your garden.

11. Primroses And Marigolds

@positivebloom

Primroses, with their vibrant spring blooms, require specific soil conditions to flourish. Marigolds, hardy and sun-loving, can easily overshadow more delicate plants.

12. Echinacea And Bee Balm

@positivebloom

Echinacea, also known as coneflower, is renowned for its resilience and drought tolerance. Bee balm, with its vibrant, nectar-rich blooms, prefers a more moisture-rich environment.

Together, they vie for differing water needs, which can lead to stress and poor growth. Separating these perennials allows each to thrive in their preferred conditions, ensuring a vibrant display.

13. Lily Of The Valley And Iris

@positivebloom

Lily of the Valley, with its sweetly scented blooms, spreads rapidly in the garden. Iris, with its elegant, tall flowers, requires space and rich soil to flourish.
