POLYSTICHUM SETIFERUM ‘DAHLEM’

Gardens Illustrated Magazine - - DIG IN -

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.
