About Bracken fern
Pteridium rostratum, commonly known as Northern bracken, is a large and vigorous perennial fern characterized by its bright green, erect, triangular fronds. This robust plant can form dense colonies, making it ideal for woodland gardens, wild areas, or for covering large expanses where lush, low-maintenance foliage is desired.
Native range
North America and parts of Eurasia
Care tips
This fern thrives in a wide range of light conditions, from full sun to partial shade, though it prefers some shade in very hot climates. It requires well-drained, slightly acidic to neutral soil and tolerates poor soils, making it highly adaptable. Watering should be moderate, allowing the substrate to dry out slightly between waterings; it is quite drought-tolerant once established. Avoid planting it in confined spaces or near sensitive crops, as it can be invasive and its aggressive growth may outcompete other plants.
