Darlingtonia is a monotypic genus consisting of only one species. This species
is endemic to mostly coastal areas of northern California and southern Oregon.
In these regions, Darlingtonia colonies can be found at various elevations; from
sea level to over 8000 feet in the mountains. A common characteristic of all
Darlingtonia populations is a wet habitat. These areas are often fed by springs
or streams flowing from higher elevations.
In Darlingtonia cultivation, various methods are often
employed in an attempt to mimic the cooling effect provided by the streams of
the natural habitat. At our nursery, we have employed a different technique. As
cold water holds more oxygen than warm water, we surmised that perhaps
oxygenated water would assist in cultivation. With the assistance of an air pump
and airstones, our plants remained healthy outdoors throughout the summer.
