About
Scrophularia aquatica is a member of the figwort genus Scrophularia (family Scrophulariaceae) and shows the genus's diagnostic square stems and opposite leaves. Its open, two-lipped flowers form clusters at stem tips and appear in the UK from June to September. Species in this genus are known to support some Lepidoptera larvae and a number have traditional medicinal uses.
About the genus
The genus Scrophularia of the family Scrophulariaceae comprises about 200 species of herbaceous flowering plants commonly known as figworts. Species of Scrophularia all share square stems, opposite leaves and open two-lipped flowers forming clusters at the end of their stems.
In the garden
Scrophularia aquatica sits within a genus of about 200 herbaceous species distributed across the Northern Hemisphere. Members share a recognisable structure: square stems, opposite leaves and terminal clusters of two-lipped flowers. The genus name reflects historical medicinal use for scrofula, and some Scrophularia contain iridoid compounds of interest. When bringing Scrophularia aquatica into cultivation, begin by noting its architecture—upright flowering stems that terminate in open, two-lipped blooms. Detailed siting, soil and exposure recommendations vary by species and by supplier, so follow nursery guidance for the stock you have. Gardeners aiming to support wildlife should consider it for areas where invertebrates are encouraged, since several species act as food plants for moth larvae. In a UK planting scheme, Scrophularia aquatica is best given space so its upright flowering clusters are visible rather than crowded by low, dense neighbours; it can work in more naturalistic or less formal herbaceous margins. Expect terminal clusters of two-lipped flowers from June to September.
