Knowra Ixora Ixora Ixora is a genus of tropical and subtropical flowering plants in the coffee family, Rubiaceae. Its species are known for dense clusters of small, vividly colored flowers.
Rubiaceae : Rubiaceae is a large family of flowering plants that includes coffee, gardenia, and ixora. Ixora belongs to this family, whose floral traits and diversity provide its taxonomic context.
Ixora coccinea : Ixora coccinea is a tropical shrub with dense clusters of red, orange, pink, or yellow flowers. It is the best-known cultivated species and a common source of ornamental ixora varieties.
Old World : The Old World is the collective name for Africa, Europe, and Asia, especially in historical biogeography. Ixora is native mainly to tropical and subtropical regions of the Old World.
Gardenia : Gardenia is a genus of evergreen shrubs and trees in the coffee family, often grown for fragrant flowers. Like ixora, gardenia belongs to Rubiaceae, but its large, usually solitary flowers differ from ixora's clusters.
Inflorescence : An inflorescence is the arrangement of flowers on a plant stem or branch. Ixora's conspicuous flower clusters are inflorescences, often dense and rounded.
Hedge : A hedge is a closely planted row of shrubs or trees used as a boundary or screen. Ixora's dense foliage and tolerance of pruning make it useful for tropical hedges.
Tropical Asia : Tropical Asia is the warm, humid region of southern and southeastern Asia near the equator. Many ixora species originate in this region, where the genus has substantial native diversity.
Pentas : Pentas is a genus of flowering plants with star-shaped flowers arranged in rounded clusters. Pentas can resemble ixora in flower display, but it belongs to a different genus within Rubiaceae.
Corolla : The corolla is the collective set of petals in a flower. Ixora flowers have narrow petal tubes ending in spreading lobes, shaping their clustered appearance.
Bonsai : Bonsai is the cultivation of trees or shrubs in containers through shaping and pruning. Small-leaved ixoras can be trained as flowering bonsai in warm climates.
