Hydrangeas are one of the most beloved shrubs in the garden, producing spectacular blooms that brighten landscapes from summer into fall.
Whether you’re creating a classic cottage garden, designing a foundation bed, or adding color to a shady corner, choosing the right companion plants can make your hydrangeas look even more beautiful.
The best hydrangea companions have similar growing requirements while adding contrasting textures, colors, and bloom times. Here are some of the best plants to grow alongside hydrangeas.

1. Hostas
Hostas are one of the most popular companion plants for hydrangeas. Their large, textured leaves create a beautiful contrast with delicate hydrangea blooms while thriving in similar light and moisture conditions.
2. Astilbe
Astilbe produces feathery flower plumes in shades of pink, white, and red that bloom before or alongside many hydrangeas. Both plants enjoy rich soil and partial shade, making them natural companions.

3. Heuchera (Coral Bells)
Colorful foliage in shades of burgundy, lime, caramel, and purple provides season-long interest beneath hydrangeas. Coral bells also help soften the edges of garden beds.
4. Ferns
For a woodland or cottage garden look, pair hydrangeas with graceful ferns. Their soft texture complements large hydrangea blossoms and creates an elegant, layered landscape.
5. Foxgloves
Foxgloves add height and vertical interest while blooming in late spring and early summer. Their tall flower spikes look stunning planted behind hydrangeas in a cottage garden border.
6. Bleeding Hearts
These charming spring bloomers provide early-season color before many hydrangeas begin flowering. Their delicate heart-shaped flowers pair beautifully with lush hydrangea foliage.
7. Japanese Forest Grass
This graceful ornamental grass adds movement and texture beneath hydrangeas. Its cascading foliage brightens shaded garden beds and creates a soft, natural look.
8. Boxwood
Boxwood provides evergreen structure throughout the year. Planting low boxwood hedges in front of hydrangeas creates a formal garden appearance while allowing the flowers to shine.
9. Hellebores
Hellebores bloom in late winter and early spring, providing months of interest before hydrangeas awaken. Their evergreen foliage also adds year-round texture.
10. Impatiens
For continuous summer color, tuck impatiens beneath hydrangeas. They thrive in the same shady conditions and fill empty spaces with bright blooms.
11. Japanese Painted Fern
If you want extra color in the foliage, Japanese painted ferns offer silvery leaves that beautifully complement blue, pink, or white hydrangea flowers.
12. Peonies
If your garden receives enough sun, peonies make excellent companions for hydrangeas. Peonies bloom earlier in the season, followed by hydrangeas, creating months of spectacular flowers.
Together they create one of the most romantic combinations for a cottage garden.
Tips for Planting Around Hydrangeas
For the healthiest plants:
- Give hydrangeas enough room for good air circulation.
- Choose plants with similar moisture requirements.
- Avoid overcrowding large shrubs.
- Layer plants by height, with taller plants in back and lower-growing companions in front.
- Add mulch to help retain soil moisture.
Hydrangeas in Cottage Gardens
Hydrangeas are a favorite in cottage gardens because they provide large, colorful blooms and pair beautifully with traditional flowers.
Mix hydrangeas with foxgloves, peonies, lavender, hollyhocks, roses, and ornamental grasses to create a lush garden filled with texture and color from spring through fall.
The key to a successful cottage garden is layering plants with different bloom times so there’s always something flowering throughout the season.
