Libertia formosa is a hardy, clump-forming evergreen perennial growing from rhizomes. It is also known as Snowy Mermaid or Chilean Iris. It is part of the Iridaceae family of plants. Libertia formosa is native to Chile. The genus was named after Marie-Anne Libert (1782-1865), a Belgian botanist, mycologist, and one of the first female plant pathologists.
Libertia formosa can grow to about 90cm or 3ft. Libertia formosa leaves are narrow and sword-shaped and the white flowers are bowl-shaped, and appear in spring and early summer. Plant it in the sun in moderately fertile and moist but well-drained soil. Remove the flower stalk after the flowering season ends and also trim any damaged leaves after winter. Propagate Libertia formosa by seed or by division in early spring. Libertia formosa is basically disease-free and pest-free.
