Used by our Saxon ancestors for ﬂavouring ale. A
strong-growing perennial, 4 feet, with inconspicuous
yellow ﬂowers. This plant makes such strong roots
that it should be given at least 2 feet each way.
Propagation is best done in autumn, splitting up the plants
into rooted bits. It succeeds in any ordinary garden soil,
poor or rich, in sun or part shade.
