Plant Description
Penstemon ‘Rock Candy Purple’ is a compact and colourful variety, perfect for
adding rich tones and tidy structure to the garden. This little powerhouse is loaded
with vibrant, bell-shaped flowers, formed from the very base of the plant and carried
in plump, upright panicles. The flower spikes rise just above a neat rosette of dark
green foliage, giving a full and balanced shape. Each upward-facing, multi-lipped
tubular bloom shows off a striking contrast in the throat, an eye-catching detail that
draws in bees, butterflies and other pollinators.
With its naturally compact habit, Penstemon Rock Candy Purple fits beautifully at
the front of borders and is equally at home in patio containers or small garden
spaces. Its tidy size and strong flowering make it an ideal choice for adding reliable
colour and structure without overwhelming nearby plants.
To keep it looking its best, plant in full sun and in well-drained soil. Avoid areas
where water may collect over winter, as like many penstemons, it prefers a drier root
run in cold months. Deadhead spent blooms regularly to encourage continuous
flowering throughout the summer. In colder areas, apply a light mulch in late autumn
to protect the roots.
With just a little care, Penstemon Rock Candy Purple will provide a long season of
vibrant colour and compact form, making it perfect for cottage gardens, modern
spaces, and everything in between.
