Purple Pitcher Plant
Nodding Onion

Purple Pitcher Plant is a native carnivorous plant, easily recognized by its purple-tinged, tubular pitchers that capture and digest insects. The nectar along the rim attracts insects to the pitcher, where slippery surfaces and downward-pointing hairs cause them to fall into the fluid below. Once inside, they are broken down, providing nutrients that allow the plant to thrive in nutrient-poor soils.
The plant produces nodding, purple-red flowers held high above the leaves. Interestingly, these blooms are pollinated by the Pitcher Plant Fly (Fletcherimyia fletcheri), whose larvae live in the fluid of the pitchers and feed on some of the trapped insects. It can be found in bogs, fens, and other wetlands. It is well-suited for wetland gardens, restoration, and naturalisation projects.
The Purple Pitcher Plant can be challenging to grow because of its specific requirements. It thrives in consistently moist (but not waterlogged), acidic soil, with a peat-and-sand mix typically recommended. The plant is sensitive to fertilizers, dissolved salts, and chlorinated water. When given the right conditions, full sun will bring out its brightest colors.
The Purple Pitcher Plant is the provincial flower of Newfoundland & Labrador.

Nodding Onion is a native perennial wildflower known for its nodding clusters of flowers that range in color from white to pink to purple. The lightly scented blooms provide pollen and nectar for pollinators, especially bees, which can collect while hanging upside down, a capability most other insects lack.

The narrow, grass-like leaves of the Nodding Onion can be used as a seasoning in cooked dishes, though bulbs and raw leaves should not be eaten in large quantities. All parts of the plant have an onion-like aroma when bruised, which helps deter deer and rabbits. They can self-seed readily, so removing spent blooms helps manage their spread. Tolerant of a range of soils, including alkaline, it is well-suited for a variety of plantings, including pollinator gardens and naturalization projects.
