WaterThe Bog Arum prefers consistently moist soil and should be watered when the top inch of the soil feels dry to the touch. Typically, this means watering the Bog Arum every few days to maintain the necessary moisture level. In terms of water quantity, this generally equates to approximately 16-32 ounces per watering, depending on the size of the pot and the environmental conditions. During particularly hot or dry periods, the Bog Arum may require more frequent watering to prevent the soil from drying out completely. Always check the moisture level before watering to avoid overwatering, which can cause root rot.
LightBog Arum thrives best in partial shade to full sun, making it versatile in terms of lighting conditions. Ideally, place the Bog Arum in a spot where it receives filtered sunlight for part of the day, or bright, indirect light. Direct sunlight, especially during the intense midday hours, should be avoided to protect the Bog Arum from leaf scorch.
TemperatureBog Arum prefers temperatures between 60 and 75 degrees Fahrenheit for optimal growth. It can survive in temperatures as low as 50 degrees Fahrenheit and as high as 80 degrees Fahrenheit. To maintain healthy growth, keep the Bog Arum away from cold drafts and extreme heat sources which can stress the plant.
PruningPruning the Bog Arum is not generally required for health reasons but may be done to maintain shape or remove dead foliage. Prune as needed, typically after flowering, to tidy the plant and encourage new growth. Use sharp, clean shears to make clean cuts, which will help prevent any potential disease issues.
CleaningAs needed
SoilBog Arum thrives in acidic soil with pH ranging from 5.5 to 6.5. A mixture of peat, sand, and loamy soil is ideal, maintaining wet or boggy conditions that mimic its native swampy habitat.
RepottingBog Arum typically does not need frequent repotting; it's best to repot once every 2 to 3 years or when it outgrows its current pot, ensuring you use an appropriate soil mix that supports its moisture needs.
Humidity & MistingBog Arum requires high humidity levels, ideally above 60%, as it naturally grows in swampy, marsh-like environments. It will thrive in consistently moist air.
Suitable locationsIndoor
Maintain high humidity and indirect light.

Life cycleCalla palustris, commonly known as the water-arum or bog arum, begins its life cycle as a seed, often germinating in the muddy substrate of freshwater habitats. Upon germination, it develops into a juvenile plant, with roots anchoring into the waterlogged soil and a rosette of floating heart-shaped leaves emerging. The plant then matures and produces its distinguishing feature: a spathe and spadix, the latter of which is a spike-like inflorescence that forms the actual flowers of the plant. After pollination, which is typically facilitated by insects, the plant produces berries that are typically green and turn to reddish-orange as they mature. Each berry contains several seeds, which are eventually dispersed by water, and sometimes by waterfowl, to new locations where they can germinate and start the cycle anew. During the winter, water-arum dies back to its rhizomes, which remain dormant until the conditions become favorable for regrowth in spring.
PropogationPropogation time
Spring to Summer
The Water Arum or Calla palustris can be propagated through division, which is the most popular method for this plant. The best time to propagate by division is in late winter or early spring, just before the growing season begins. To do this, carefully lift the plant from the soil and gently separate the rhizomes, ensuring that each section has at least one growth point. These divisions should then be planted in containers filled with a mix of peat and perlite or directly into a boggy soil area, maintaining the same soil depth as they were previously grown. Water well after planting, and maintain consistently moist conditions as the new plants become established.
