Calla Lily

Brief Description

An elegant herbaceous perennial known for its distinctive funnel-shaped spathe (modified leaf) surrounding a central spadix, with arrow-shaped green leaves that often feature white speckles.

Care Instructions

Provide bright, indirect light and keep soil consistently moist but not soggy during the growing season. Use well-draining soil and fertilize monthly with a balanced liquid fertilizer. Reduce water after blooming to allow for a dormancy period.

Medicinal Value

We do not currently provide medicinal value for plant identifications.

Sunlight

Full sun to partial shade; prefers at least 6 hours of bright light daily. Indoors, place near a bright window but avoid direct harsh afternoon sun.

Watering

High; maintain evenly moist soil. Do not allow the pot to dry out completely during the flowering season. Cut back on watering once foliage begins to die back for dormancy.

Soil

Rich, moist, well-draining soil. Prefers slightly acidic to neutral pH (5.6 - 6.5).

Hardiness Zone

8-10 (can be grown as annuals or houseplants in colder regions)

Growth Habit

Perennial herb growing from rhizomes. Forms clumps reaching 12-36 inches in height and 12-24 inches in spread.

Bloom Season

Spring and early summer; produces trumpet-shaped flowers (spathes) in white, yellow, pink, or deep purple.

Toxicity

Toxic to humans, dogs, and cats; contains calcium oxalate crystals which cause intense oral irritation, swelling of the mouth/throat, and digestive upset if ingested.

Propagation

Division of rhizomes during the dormant season or by seed, though seeds take longer to mature into flowering plants.

Common Pests & Issues

Prone to root rot if overwatered. Susceptible to aphids, spider mites, and bacterial soft rot. Yellowing leaves may indicate too much water or lack of light.

Similar Species

Peace Lily (Spathiphyllum) - distinguished by softer leaves and different spadix structure; Canna Lily - distinguished by much larger foliage and true petal-like flowers.

Interesting Facts

Despite their name, Calla Lilies are not true lilies (genus Lilium). They are widely used in bridal bouquets as a symbol of purity and rebirth, and they are the national flower of Saint Helena.
