I have sown Lingholm (got them from Chilterns Seeds), and although the germinated and grew on, they didn't survive the winter, so, being biennial (or short term perennial), i never saw them flower.
They need very special conditions from what I gather - rich, well drained, but moisture retentive acid soil in semi shade, and better in the cooler Northern half of the country.
We were high up in the Welsh hills, had acid soil that was moisture retentive, but it was not so well drained so the roots were in soggy soil in winter and I think that did for them.
Although Chiltern Seeds claimed this variety was not monocarpic (did not die after flowering in year 2), I read other stuff that suggested that unless you had super soil conditions the flowering would exhaust the root system. Well, I had my go at it, because they look so lovely, but have resigned myself to never growing them successfully, especially now I am in alkaline heavy clay with no shade in Lincolnshire!
