– Venus’s Flytrap 13 deg C (55 deg F). South Carolina.
These insectivorous plants trap the animal protein that they need, but it is possible to keep thriving plants of this kind bythem ordinary mineral or vegetable nitrogen and other nutrients.
The end half of the Dionaea muscipulais modified into two pads with teeth on the margins and bristles in the leaf centre. When the central bristles are touched by a fly or other insect the two parts of the leaf fold together so that the teeth interlock and the insect is then trapped inside, to be digested at leisure by the plant. It sounds gruesome, but is a fascinating thing to watch.
It is a small plant no more than 15 cm (6 in) tall when in flower, and consists of a rosette of leavesclose to the soil for the rest of the year.
Theare white and quite pretty, blooming in mid summer.
