The
'flower of the poets', the lily of the valley was a
British wilding most often found in moist woods and
glens. As a popular garden plant it was particularly
suited to similarly wild, moist positions within the
garden, and was a favourite button-hole flower among
gentlemen.
They
were sometimes grown very successfully in the forcing
pit for out of season flowers so long as the gardener
followed one simple rule: to force slowly in a temperature
of between 50 to 60 d. Fahrenheit, and not to exceed
that heat.
