Penstemon 'Andenken An Friedrich Hahn' Overview

Penstemon 'Andenken an Friedrich Hahn' is a semi-evergreen, bushy perennial that produces stunning wine-red flowers with white strip marking inside. Also known as a Beardtongue, this plant gets to 90 cm tall and makes a beautiful addition to flower borders. Deadheading the spent stems of Penstemon will encourage new flowers and extend the summer display. Needing very little water once established, this plant only needs mulching in late autumn and cutting back in spring to help prevent frost damage. Developed in 1918, this Penstemon is one of the oldest hybrids and was previously known as Penstemon 'Garnet' and is occasionally still sold with this name. This cultivar has been awarded an RHS Award of Garden Merit.
