which habitats do butterwords grow?
the exception of
the Australian continent, butterworts can be found worldwide,
especially in the northern hemisphere. In Africa Pinguicula
species are only found in the northern parts along the coast of the
Mediterranean Sea. The main centre of diversity is the
Carribean/Mesoamerican region, where 2/3 of the butterwort species can
be found. A secondary centre of diversity is the European continent,
but with a much smaller number of distinctive species.
carnivorous plants, butterworts have become specialized to grow in
habitats where the soils are quite poor in nutrients. The advantage of
using nutrients of animal origin is that it allows them to live in
habitats where other plants can't grow very well. So it is not
astonishing that butterworts can be found in areas like bogs, eroded
soils or even bare rocks.
