Lily of the Valley
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.
