Sansevieria 'Horwood' was named by Grigsby based on the collection Frank Horwood # FKH 424 which is without locality data but believed to be from Kenya. Identical plants were collected 10 km northwest of Kibwezi on the Nairobi-Mombasa road by Juan Chahinian in 1992. The name Sansevieria horwoodii has become widespread in the horticultural trade but has never been formally published. Sansevieria ‘Horwood’ (called by some Sansevieria elliptica ‘Horwood’) is a very attractive stemless plant with dramatic green leaves with grey-white mottling, rough on the underside. The flattened leaves of great thickness, give it, too, an extremely distinctive look. The spectacular inflorescence reaches about 70 cm in length, and the flowers are nice too.Leaves: Usually 2-5 per growth, up to 75 cm long, 7.5 cm wide spreading in all directions, sometimes up to 8 or more in a rosette, rigid, lanceolate to oval, thick and wide in the middle, held more or less horizontally, sometimes twisted, with a tapered tip. Upper surface smooth, but not glossy and leathery, dark green, slightly bluish in young leaves, with shades of grey in the form of whitish or silver green spots and there are also dark green longitudinal lines. Leaf edge red, extending on both sides of the leaf surface.
