About
Blechnum brasiliense is a perennial fern that typically grows to a height of 1.5 meters and spreads about 1 meter. Its fronds, which are either upright or gracefully arching, display a subtle crinkled texture. Young fronds initially appear in a vibrant pinkish-red hue before transitioning to a rich, glossy green as they mature. The fern develops an upright rhizome that can eventually create a slender trunk measuring approximately 30 centimeters in height.
About the genus
Blechnum consists primarily of evergreen ferns characterized by upright or spreading rhizomes. The fronds are typically simple and pinnate, with fertile fronds standing upright while the sterile ones tend to spread out.
