Shark Fin Cactus (Epiphyllum Chrysocardium)A super unique trailing cactus that needs slightly different care, and rewards with beautiful, big flower blooms each year (hence their name). Shark Fin Cactus like to be in bright, indirect light avoid full sun for long periods of time. In the spring fall (growing season), keep the soil moist but water much less in the winter. Avoid moving the plant too much, especially when it's blooming. Pet friendly!
