Neutral Cretaceous On Apr 7, 2007, Cretaceous from El Sobrante, CA (Zone 9b) wrote:

Native to New Zealand. Available from Thimble Farms, B.C., Canada.

Positive growin On Dec 29, 2005, growin from Vancouver, BC (Zone 8b) wrote:

Dark green foliage, graceful & elegant. Although defoliated at -15C, regrew from the roots to a nice multi-stemmed treefern. I prefer this species over D. antarctica.

This tree-fern is from New Zealand, where it is one of the commonest tree-ferns, although I didn't see when I visited new Zealand.
In New Zealand, it is known by the Maori name of Wheki.

Positive palmbob On Sep 13, 2003, palmbob from Acton, CA (Zone 8b) wrote:

Though less common than its cousin D antartica, this is a nicer looking, neater fern, with an almost black, straight, thinner trunk and whitish undersides to the leaves. It is a much slower grower which is probably why it's not caught on in the nursery trade, yet, but a mature plant (no photos, yet) of this is a magnificent sight. It can sucker, which, to me is a little unusual for a tree fern.
