Lepismium cruciforme, commonly known as Cruciform Cactus, is an epiphytic cactus native to the Atlantic Forest biome in South America, specifically in regions of Argentina, Brazil, and Paraguay. It is typically found in subtropical or tropical moist lowland forests, often growing on trees. This species can reach a length of up to 1 meter, with segmented, flattened stems that may have a slight reddish tinge under high light conditions. The small, bell-shaped flowers are white to pink and bloom sporadically throughout the year, with a peak in late spring to early summer. The flowers are not particularly showy but add a delicate charm to the plant.

Cruciform Cactus is valued for its unique, sprawling growth habit and is often grown in hanging baskets or mounted on bark to mimic its natural epiphytic state. It is relatively easy to maintain, requiring a humid environment and partial shade to replicate its native forest canopy conditions. Well-drained soil or orchid potting mix is essential to prevent root rot. In cultivation, it is important to avoid overwatering and to provide good air circulation. While it is not known for significant pest or disease issues, it can be susceptible to mealybugs and fungal infections if conditions are too damp. This cactus is not typically invasive when grown outside its native range, but it should be protected from frost.CC BY-SA 4.0
