Ploughman's-spikenard is a rosette forming, short lived, winter-green perennial found on dry and reasonably infertile sites on chalk or limestone. It is most at home on open, stony ground but can be found in grassland, on banks, in woodland rides and within scrub but almost never under shade. It should be noted that this species is toxic to sheep and cattle and we therefore recommend you do not use it on site that are regularly grazed sites.
Seed is best sown in the autumn.
