Expert Tip

S. sanguinea thrives in a bright indirect light, but due to its patterned leaves, the plant requires much more light than many similar plants in the Calathea family in order to thrive. In full shade, the plant will lose its beautiful variegation and the leaves become solid green.
Care & Size Guidance 

Care & Size Guidance 

Consistent watering is key with S. sanguinea. Keep soil slightly moist, making sure to not let it dry out too much or become too soggy, as they are susceptible to root rot. Unlike many actual Prayer Plants, S. sanguinea’s leaves do not clearly lower when they need watering.

Repotting should be done every other year in spring. Soak the root ball well before removing the plant from the pot to prevent the delicate roots from drying up during the process.

Though they can flower, they don’t often flower indoors in the UK climate.
