POLYSTICHUM SETIFERUM ‘DAHLEM’
A fairly recent selection of the, erect growing form of the soft shield fern that was discovered at Dahlem Botanical Garden in Berlin. It’s a very decorative fern with fresh, delicate and finely serrated leaves and is an excellent groundcover for growing beneath shrubs and trees. Like many polystichums it makes bulbils along the midrib. When the fronds are anchored to the soil, the bulbils start to root, propagating new ferns. It is close to the form of ‘Divisilobum’ and in some classifications falls within that group.
Height 70cm. Origin Garden origin (species Europe). Conditions Moist but well-drained soil; part to full shade. Hardiness RHS H7, USDA 6a-8b. Season of interest Year round.
