Schwarzenberg is located in the midst of forested hills in the Erzgebirge/Vogtland Natural Park. The flat Galgenberg dome is mostly covered by coniferous forest. Thick copse of sycamore, aspen, mountain ash, hazel and wild cherry grows on the terraces at the forest edge. Sporadic beech and Weymouth pine can be found on the Ottenstein. The feverfew-like Tanacetum parthenifolium, known locally as Schwarzenberger Edelweiß, has found a curiously isolated habitat in Schwarzenberg and has resisted attempts at shifting or cultivation.
