Epiphyllum

Often referred to as orchid cacti or climbing cacti, Epiphyllum is a genus of tropical succulents. There are more than a dozen types and hundreds of related hybrids that vary in shape and size. They usually have long, flat, non-spiny, and trailing stems. In the spring or summer, they display bright, large, fragranced and night blooming flowers with proper care. Instead of developing roots on the ground, these usually epiphytic plants emerge from tree branches or trunks.
