Penstemon ‘Andenken an Friedrich Hahn’ bears rich dark red, trumpet-shaped flowers with distinctive white-striped throats throughout summer. It has a bushy habit and narrow green leaves.

Bred in 1918 and previously known as ‘Garnet’, it is one of the oldest Penstemon hybrids. It grows well in fertile, moisture-retentive soil with good drainage, in sun or partial shade.

Hardiness: H5 (−15°C to −10°C). Hardy through most UK winters, including severe cold. Choose a sheltered position in colder or exposed areas; plants in pots are more vulnerable to frost.
