Dicksonia antarctica is a large, evergreen tree fern native to eastern Australia. With a dramatic vase and architecturally distinctive form, they typically grow to 12-15′ in height. They feature a thick single trunk that is covered in decaying remains of earlier plant growth which forms the medium through which roots grow. The stipe or frond area that joins the trunk is coarse up to the crown. Large, dark green, roughly-textured fronds spread out from the trunk center to form a canopy of fronds that can be 6-7′ long. It grows slowly and can produce reproductive spores for about 20 years. If you’re looking for a handsome tree fern that commands attention in a Bay Area garden, this is a great candidate.
