Fraser’s St. John’s wort (Hypericum fraseri, syn. Triadenum fraseri) is a perennial plant 30 to 60 cm tall, with an upright and delicate shape. Its smooth, reddish stems bear opposite, oval leaves attached directly to the stem and ranging from bluish to grayish green. In summer, it produces small pink flowers with five petals, about 1 to 2 cm in diameter, grouped at the tips of the stems.
In Quebec, Fraser’s St. John’s wort grows in open wet habitats such as bogs, marshes, and lake edges. It prefers organic or sandy soils that are always moist or temporarily flooded. It is typical of shallow bog areas, often found alongside other wetland plants such as bogbean and cotton-grass.

Ecological roles
Fraser’s St. John’s wort contributes to wetland biodiversity by providing nectar and pollen for various pollinating insects, including wild bees and hoverflies. Its foliage and fine stems offer shelter for small invertebrates, while its roots help stabilize peat soils and retain moisture. Its presence indicates a healthy, well-balanced wetland with little disturbance.
