Greigia is a genus of flowering plants in the family Bromeliaceae (subfamily Bromelioideae), order Bromeliales. It comprises around 30–40 species native to Latin America, ranging from Mexico south to Chile, with the greatest diversity in the Andean cloud forests of Colombia, Ecuador, Bolivia, and Chile.
Plants in the genus share the rosette growth form typical of bromeliads, with stiff, often spiny-edged leaves. What sets Greigia apart from the vast majority of bromeliads is its perennial flowering habit: whereas most bromeliad genera are monocarpic — dying after a single flowering event — Greigia plants continue to bloom year after year from the same rosette. This trait makes the genus of particular horticultural interest among bromeliad enthusiasts.
Species occur across a broad range of habitats from coastal scrub to montane forest and high-elevation paramo, with several species restricted to specific countries or island groups such as the Juan Fernández Islands (G. berteroi). The genus includes both terrestrial and epiphytic species.
Etymology
The genus name Greigia honours Major General Samuel Alexjewitsch Greig, who served as president of the Russian Horticultural Society in 1865.
Distribution
Greigia is native to Latin America, distributed from Mexico in the north to Chile in the south. Species occur across Central America, the Caribbean slopes of the Andes, the Juan Fernández Islands, and the temperate forests of Chile, with the highest species richness concentrated in Andean South America.
