The tidy, rather humble rosette of evergreen grassy foliage doesn't hint at the exotic and unexpected pink flower spike that emerges in summer. Sticky hairs hide under the flowers which trap insects for food. The phrase "trigger plant" in the common name comes from the pollination mechanism. The stamens are held "cocked" behind the flower, and when an insect pushes into the flower to access nectar, the pollen-loaded stamen is "triggered" and whacks the insect, which results in a pollen-covered insect.
