Sulphur-Flower Buckwheat

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.

Sulphur-Flower Buckwheat is a native perennial wildflower known for its dense clusters of cream to yellow flowers. The long-lasting blooms persist from late spring into summer, providing an extended nectar source for a variety of pollinators. The flower buds are often red-tinted before opening. As the blooms age, they shift to orange or red, adding seasonal interest and making them well-suited to dried flower arrangements. Its seeds are also eaten by birds, adding to its ecological value.

Depending on climate and conditions, Sulphur-Flower Buckwheat may be evergreen to semi-evergreen, or its foliage may turn red during fall. Its deep roots and spreading growth stabilize rocky or sandy soils, making it useful for erosion control. Exceptionally hardy once established, it requires little care and thrives in challenging environments, making it an excellent choice for pollinator gardens, naturalization, and ecological restoration projects.
