Weld is a biennial or perennial herb with short-stalked lanceolate alternate leaves. The tiny flowers usually have four pale-yellow petals and four sepals, and they occur in flower spikes typically 20cm long but exceptionally up to a metre.

Blooming times

The flowers of Weld appear from June until August.


Weld is widespread and fairly common throughout Britain and Ireland, although more so in the drier areas of the south and east.


This plant is also known as Dyer's Rocket, because of the yellow flavone dye derived from it.
