Sansevieria trifasciata 'Black Coral' - A clumping plant to 3 feet tall with narrow leaves with vertically wide gray-green wavy horizontal bands over a dark green background. The leaves are so dark when they first emerge they almost appear black and these younger leaves lack any of the banding that shows up as the leaves age. Plant in part sun or bright to deep shade in a well-drained soil and irrigate regularly to occasionally in the warmer months. As with many other Sansevieria trifasciata varieties this plant if easy-to-grow as an indoor plant or outdoor in near frost free climates in a pot so long as soil drains adequately and is kept relatively dry through the winter months - a great plant under a protected eave. Not that this plant would seem to be attractive to pets but we do need to note that the ASPCA lists Sansevieria trifasciata as poisonous to dogs and cats, noting they can cause nausea, vomiting and diarrhea. On the flip side, in 1989 the National Aeronautics and Space Administration (NASA), in collaboration with Associated Landscape Contractors of America (ALCA), published "A study of interior landscape plants for indoor air pollution abatement" authored by B. C. Wolverton, Willard L. Douglas and Keit Bounds, that listed as Sansevieria trifasciata as a plant that reduced certain pollutants (benzene, formaldehyde, trichloroethylene, xylene and toluene ) concentrations in the air. Because of this study these plants are sometimes marketed as "fresh air" plants that filter toxins from the air. This cultivar plant is sometimes confused in the trade or claimed to be synonymous with an older Sansevieria trifasciata variety called 'Black Gold', which should have a yellow margin that this one lacks. Long placed in the Agavaceae, the Dracaenaceae and by some in the Ruscaceae families, Sansevieria was most recently placed in the subfamily Nolinoideae within the Asparagaceae family. Molecular phylogenetic studies however have determined that Sansevieria should actually be included in the genus Dracaena and so this plant would correctly be called Dracaena trifasciata. Because of the long standing use of its old name, and to not cause customer confusion, we continue to list this plant under its previous Sansevieria name. We received this very nice cultivar in 2010 from noted plantsman and aloe hybridizer John Bleck.  Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Sansevieria trifasciata 'Black Coral'.
