Porsild's Braya

Braya humilis subsp. porsildii

Porsild's Braya (Braya humilis subsp. porsildii) is a low-growing, mat-forming plant. This species is native to the Arctic tundra of Northwest Territories in Canada and is nationally rare and an endangered species. It is a perennial wildflower grows to a height of 2 - 7 cm and is characterized by its small, white or yellow flowers. The plant is associated with calcareous bedrock and mossy meadows and prefers soil rich in calcium carbonate. It is an important food resource for wild animals and helps in providing substances essential for plant nutrition. Porsild's Braya is one of the few species which grow in the rapidly changing Arctic terrain and provides a crucial habitat for migratory birds.

watering

Water the Ellesmere Island Braya (Braya humilis subsp. ellesmerensis) with 1/2 cup of water 2 times a month during its growing season. Water slowly and thoroughly until the entire root zone is damp but not saturated. Avoid wetting the foliage to prevent fungal diseases. Reduce watering frequency in the winter when the plant is dormant. Do not let the plant dry out completely for more than a few days.

sunlight

Ellesmere Island Braya is native to the high Arctic tundra on Ellesmere Island, Nunavut, Canada. This species requires full sun and is best suited to long days of summer sunlight. It thrives in regions that receive 8 to 15 hours of direct sunlight during the growing season (June-September). The optimal sun exposure in this area is south and west exposures. In areas that receive less sunshine, this plant will need extra care and attention to ensure it stays properly hydrated and does not suffer from sunburn.

pruning

Ellesmere Island Braya should be pruned after flowering. This plant species needs minimal pruning and should only be done if dead or unhealthy looking foliage needs to be removed. Pruning should be done late in the winter season, when the plant is not actively growing. The bare stems should be cut back to the main plant framework, being careful not to take too much tissue. This will encourage a healthy bush-like shape. No more than 20 to 25 percent of foliage should be removed when pruning, to avoid damaging the plant.
