In the garden

Veratrum viride is a tall perennial herb native to eastern and western North America. It produces a large branched flowerhead in early summer, with flowering recorded in June to July in the UK. For best results plant it in full sun on soils that retain moisture: sandy, loamy or clay soils are all acceptable so long as they remain moist or wet rather than bone dry. Hardiness is H7 in the UK, meaning it is fully hardy outdoors; it also corresponds to USDA zones 3–7. Allow room for its mature height of around 2.0 m when siting, and expect an imposing vertical presence rather than a ground cover. Avoid placing it where pets, particularly dogs, might access foliage, because it is toxic if eaten. It suits damp sunny margins, pond edges and larger-scale perennial or meadow-style plantings where moisture is reliable and the size of the plant can be accommodated. Wear gloves and other protective equipment when planting or dividing to avoid contact with sap and root material.
