Penstemon digitalis Dakota Burgundy ('Tnpendb') (PBR) (Dakota Series)
beard tongue
Not only hardy, 'Dakota Burgundy' is also remarkably frost tolerant. Beautiful crimson-bronze foliage matures to dark green on this compact and dwarf perennial setting the stage for the prolific lavender-pink 'foxglove-like' trumpets that smother the plant from midsummer. Avoid waterlogged conditions over winter and look forward year-on-year to predictable penstemon perfection!
How to care for Penstemon digitalis Dakota Burgundy ('Tnpendb') (PBR) (Dakota Series):
Plant penstemons in well-drained soil in a sunny or lightly shaded position, incorporating compost or well-rotted manure to improve fertility. Water regularly until established, then reduce watering, as they prefer drier conditions once settled.
Deadhead faded blooms frequently to extend the flowering season. In autumn, leave the top growth in place to provide winter protection, then cut back in spring when new shoots emerge lower down the stems.
Apply a dry mulch, such as bark or composted straw, around the base in colder regions to insulate the roots from frost. Every few years, lift and divide congested clumps in spring to maintain vigour and encourage fresh growth.
