Often confused with Running Cedar, this clubmoss is flat-branched, and is also called “Ground Pine” due to its resemblance to a tiny pine tree. I would say (from a lay observational perspective) that the Princess Pine is more upright, prickly and stiff of a clubmoss than Running Cedar, which is less stiff and isn’t very prickly at all. The plant has an upright stem, with branches, those branches having further branches, and so on – so it’s rather tree-like.
It also has a stem that goes underground and becomes horizontal.
