Calla lilies (Zantedeschia spp.) thrive in moist, well-drained soil with partial to full sunlight. They prefer slightly acidic to neutral pH levels and benefit from consistent moisture. When selecting companion plants, it's essential to choose species that share similar environmental needs to ensure harmonious growth and mutual benefits.
Companion plants should complement calla lilies aesthetically and functionally. Below are some ideal choices:
Ferns, such as maidenhair fern (Adiantum spp.) or ostrich fern (Matteuccia struthiopteris), are excellent companions. They thrive in similar moist, shaded conditions and provide a lush, textured backdrop that highlights calla lilies' elegant blooms.
Hostas are shade-tolerant perennials with broad, variegated leaves that contrast beautifully with calla lilies' slender foliage. Their low-maintenance nature and preference for moist soil make them a practical pairing.
Astilbes produce feathery plumes in shades of pink, white, or red, which complement calla lilies' trumpet-shaped flowers. Both plants enjoy moist soil and partial shade, creating a cohesive garden bed.
Heucheras offer vibrant foliage in colors like purple, bronze, or lime green, adding visual interest alongside calla lilies. Their compact growth habit and tolerance for damp conditions make them ideal neighbors.
For a pop of color, impatiens are a great choice. These annuals flourish in shady, moist areas and bloom profusely, creating a vibrant contrast with calla lilies' subdued elegance.
Some plants not only enhance aesthetics but also improve growing conditions for calla lilies.
Creeping Jenny (Lysimachia nummularia) is a low-growing ground cover that helps retain soil moisture and suppress weeds. Its bright yellow-green leaves create a striking contrast with calla lilies' dark green foliage.
Marigolds (Tagetes spp.) deter pests like aphids and nematodes, protecting calla lilies. Their sunny blooms also add a cheerful touch to the garden.
Not all plants pair well with calla lilies. Avoid species that prefer dry or arid conditions, such as lavender or succulents, as their watering needs conflict. Additionally, aggressive spreaders like mint can overwhelm calla lilies' growth.
For a balanced design, layer plants by height, placing taller species like astilbes behind calla lilies and low-growing plants like heucheras in front. Use contrasting textures and colors to create visual depth, and ensure all plants have adequate space to thrive.
