White Fringe Tree

Blue Flax is a native perennial wildflower known for its blue to violet flowers. Each flower lasts just a single day, but new blooms appear continuously, providing weeks of colour. This extended flowering period provides a reliable display from late spring into summer and attracts a variety of pollinators.

They can self-seed readily, so removing spent blooms helps manage their spread. Birds feed on the seeds, and when cooked, they are edible and are described as having a mild, nutty flavour. The plant grows in loose clumps with slender stems and fine foliage. Young plants are leafy, but as they mature, most leaves are shed.

Blue Flax grows well in a wide range of soils, including poor or sandy conditions, and is drought-tolerant once established. The deep root system helps to stabilize soil and prevent erosion. They are well-suited for pollinator gardens, restoration, naturalization, and xeriscaping projects.

As a perennial, it dies back to the crown each winter, it will regrow from the base in the spring. Avoid disturbing the crown during late winter to ensure healthy growth the following season.

White Fringe Tree is known for its fringe-like white flowers. It can either grow as a small tree or a large multistemmed shrub. The White Fringe Tree has separate male and female plants. Both male and female flowers have white fringe-like petals, but the male flowers are longer and showier. The female flowers give way to clusters of dark blue to black berries. These berries are not edible for humans but attract birds and other wildlife.

The White Fringe Tree is tolerant of clay soils, saline soils, and air pollution but does not do well in prolonged dry conditions.
