Black Goldfish Plant 6 Pot Live House Plant NementanthusBotanical Name: Nematanthus NervosusCommon Name(s): Nematanthus Black GoldfishDescription: Nematanthus Black Goldfish House Plants have hundreds of small, thick, shiny, dark green leaves and colorful flowers that resemble tiny goldfish. The flowers on a Goldfish Plant may be red, orange, or yellow. I find Goldfish plants are easy to care for, drought resistant, and with proper care bloom on and off all year.
