THE BLADDERWORT FAMILY
 
The bladderworts are common in wetlands and moist forests. These plants are annual or perennial herbs that capture insects with sticky glands on the leaves. The insects are digested by the plant in order to obtain nutrients, like nitrogen, which are not readily available in their environment. The leaves can be clustered in a basal rosette or alternate on the stem. The flowers are either solitary or in an unbranched cluster. There are four or five sepals fused together into two lips and five petals, also fused into two lips. The petals have a spur at the base. There are two fertile stamens and occasionally two non-functional stamens in each flower. The fruit is a capsule.

HOW TO IDENTIFY COMMON BUTTERWORT
  * Are the flowers violet and with a spur?
* Are the plants about 10 cm or slightly taller?
* Do the leaves have hairs used to catch insects?
* Did you find it in a moist area in Saskatchewan?
If you answered yes to all of these questions, you may have found common butterwort!
