Description and Ethnobotany
Growth Form | Epiphytic cactus that grows up to 6 m tall in the wild. |
Foliage | This species does not produce leaves. Instead, they produce modified stems that look like leaves and serve similar functions. |
Stems | Flattened stems are composed of a thick, round midrib surrounded by fleshy wings that have a scalloped edge. |
Flowers | Fragrant, star-shaped flowers (28 cm long, 13 cm wide) are composed of 25-30 white, linear petals. Flowers begin to open at 8-10PM, reach their maximum fullness at 12-3AM, and close before dawn. Flowering occurs infrequently, about 25 days after a significant drop in temperature. Flower buds are produced at the end of modified stems that look like leaves. They swell slightly several hours before blooming later at night. |
Habitat | Found growing high in the canopy in rainforests and temperate forests. |
Cultivation | Although it is a cactus, it prefers moist, but well-drained soil. The soil should not be allowed to dry out before re-watering. |
Etymology | The genus 'Epiphyllum' means 'upon the leaf' which refers to their epiphytic nature and growth within the forest canopy. The specific epithet 'oxypetalum' refers to the pointed petal tips. |
Ethnobotanical Uses | Edible Plant Parts : Edible Flowers Medicinal: In Taiwan, the flowers are harvested at night and dried the next day. The flowers are boiled in soup and thought to be good for the skin. It is said that the plant can be used to treat pulmonary tuberculosis with cough, hemoptysis, uterine bleeding, and pharyngitis. |

I am a dedicated enthusiast with an extensive background in botany and horticulture, particularly in the realm of cacti and succulents. Over the years, I have not only cultivated a profound passion for the subject but have also engaged in hands-on experiences, including the cultivation and study of various plant species. My knowledge extends to the taxonomy, characteristics, and cultivation practices of a wide array of plants, allowing me to provide detailed insights into specific species like the Epiphyllum oxypetalum.
