  • water dropWater

    For the Calla Lily 'Snow Storm', the watering needs are moderate. Aim to keep the soil consistently moist, but not soggy. During active growth in spring and summer, water thoroughly once the top inch of soil feels dry to the touch, which might be once or twice a week, depending on climate conditions. Each watering session should provide enough water to soak the root zone; for a potted plant, this might be around 16-24 oz of water. It's vital to reduce watering frequency in the winter when the plant is not actively growing, perhaps to once every couple of weeks, depending on the dryness of the indoor air.

  • sunLight

    The Calla Lily 'Snow Storm' thrives best in bright, indirect sunlight. An ideal spot would be near a window that receives plenty of light but is shielded from the harsh afternoon sun. They can tolerate some direct sunlight, especially in the morning, but should be protected from strong, direct sunlight during peak hours to prevent leaf scorch.

  • thermometerTemperature

    Calla Lilies 'Snow Storm' prefer temperatures between 60 and 75°F for optimal growth. They can endure temperatures as low as 50°F but should not be exposed to temperatures below that as they are sensitive to cold. In their dormant period during winter, cooler temperatures around 50-55°F are acceptable, but always avoid frost which can be detrimental to the plant.

  • scissorsPruning

    Pruning Calla Lily 'Snow Storm' primarily involves removing spent flowers and yellowing leaves to promote healthy growth and improve the plant's appearance. Cut the dead material at the base without damaging the main stem. Pruning is best done after the blooming season, typically in late summer or fall, when the plant begins to enter its dormant period.

Regularly check the soil acidity, adjusting with lime or sulfur as needed to maintain the optimal pH range.

  • circleLife cycle

    Zantedeschia 'Snow Storm' (PBR), commonly known as Calla Lily 'Snow Storm', starts its life cycle as a rhizome, which is a type of underground stem that stores energy for the plant. The rhizome sprouts into leafy growth that may initially produce only foliage, gathering energy through photosynthesis. In the flowering stage, the plant produces its iconic flowers consisting of a spadix surrounded by a large, often white spathe that can occur in spring or summer depending on the climate and growing conditions. After pollination, typically by insects, the flowers may produce berries containing seeds, although commercial propagation is more commonly through division of rhizomes. As the growing season concludes, the above-ground portion of the plant dies back, and the rhizome enters a dormant period, particularly in cooler climates. With the return of warmer temperatures and growing conditions, the cycle begins anew as the rhizome again sends up shoots, repeating the life cycle.

      Spring-Early Summer

    • Zantedeschia 'Snow Storm', commonly known as the Calla Lily, can be propagated most effectively through division of its rhizomes. The best time for division is during the plant's dormancy period, usually in the fall after the foliage has died back or in early spring before growth resumes. To propagate, carefully lift the clump of rhizomes from the ground using a spade and gently separate them by hand, ensuring that each section has at least one growth point or eye. Replant the divisions immediately at a depth of about 3 to 4 inches (7.5 to 10 centimeters), spacing them about 12 inches (30 centimeters) apart to allow enough room for growth. Water the newly planted divisions well to help establish them. Division helps rejuvenate overcrowded clumps and stimulates vigorous growth in the next growing season.
