About the genus
Arisaema is a large and diverse genus of the flowering plant family Araceae. The largest concentration of species is in China and Japan, with other species native to other parts of southern Asia as well as eastern and central Africa, Mexico and eastern North America. Asiatic species are often called cobra lilies, while western species are often called jack-in-the-pulpit; both names refer to the distinctive appearance of the flower, which consists of an erect central spadix rising from a spathe.

In the garden
Arisaema ringens f. glaucescens is a member of the Araceae and displays a distinctly columnar upright habit with deciduous leaves and a defined early-summer flowering season from May to July. The plant suits locations away from full sun and benefits from a sheltered aspect where wind exposure is limited. Plant in partial shade in loam or sandy soils that stay moist but drain freely; neutral to acidic pH is appropriate. It is classed H4 for UK hardiness (average), so choose a sheltered site and avoid exposed corners where winter cold and drying winds reach the crowns. Use it in cottage and informal gardens, underplanting of roses and shrubs, or in mixed flower borders and beds where a vertical element is required. Its columnar shape means it sits neatly beneath shrub canopies or between clumps of herbaceous perennials without spreading across the border. Place so the flowering stem is visible from paths or seating areas to make the most of the May–July display.
