Sinningia speciosa: The Exquisite Florist's Gloxinia

The Velvet-Petaled Gloxinia

Sinningia speciosa, universally known as Gloxinia, Florist's Gloxinia, or Brazilian Gloxinia, is a beloved flowering houseplant celebrated for its large, velvety, bell-shaped blooms in rich jewel tones. Native to Brazil, it has been cultivated and hybridized extensively since the 19th century.

Spectacular Floral Display

The flowers are the star attraction—large (3-4 inches), trumpet-shaped blossoms with ruffled petals in shades of deep purple, crimson, pink, white, and bicolors. The velvety texture and saturated colors give them an almost artificial beauty. Blooming typically occurs in late spring to summer, lasting several weeks with proper care.

The plant forms a compact rosette of fuzzy, ovate leaves emerging from a tuberous rootstock. After flowering, it naturally enters dormancy—the foliage dies back and the tuber rests before resprouting.

Indoor Cultivation Essentials

Gloxinias prefer bright, indirect light (east or north windows), consistent moisture (water from below to avoid wetting leaves), high humidity, and temperatures of 65-75°F. Feed regularly during active growth. After blooming, reduce watering to induce dormancy, store tubers cool and dry, then repot in fresh soil for the next cycle.
