Ruellia tweediana

Ruellia, Mexican-Petunia

Ruellia simplex Wright

rue-ELL-ee-ah SIMM-plex

Acanthaceae

Explanation of name:  Generic name for Jean de la Ruelle, 1474-1537, French physician and botanist (BA1). Simplex means simple, not compound.

Synonyms:  In literature the names R. brittoniana and R. tweediana are used in almost equal measure for this species.  However, contemporary taxonomists have placed both names in synonymy.  According to Acanthaceae specialist Dr. Thomas Daniel (pers. com. June 2010) R. simplex is for the moment the preferred name for this species complex still under investigation.  Readers needing an update subsequent to the present book should consult Flora of North America. See Dawriniana.  Also see http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?32500

Natural range:  Mexico, invasive in Florida.

Recognition:  Erect perennial or subshrub with opposite lanceolate leaves.  Flowers violet, narrowly funnel-shaped, the 5 lobes wrinkled, irregularly toothed at the margins.

Note: There are several native species of Ruellia in Florida. Ruellia caroliniensis (J. F. Gmel.) Steud. is available commercially as a native alternative to the exotic invasive species. The native species prefers dry conditions. It is smaller and has pinkish (vs. purplish) flowers.

Landscape uses:  An aggressive, tough spreading, flowering subshrub valued for borders, clumps, and filling space. This Florida Exotic Pest Plant Council Category I invasive exotic is not recommended for cultivation.
