Plant Description
Penstemon Rock Candy in the colour of Ruby is a compact and striking variety, brimming with deep ruby-red, bell-shaped flowers that bring warmth and richness to the garden.
Each bloom is held in tidy, upright spikes that rise just above a low, neat rosette of
dark green foliage. The upward-facing, multi-lipped flowers feature a soft touch of
white in the throat, creating a gentle contrast that makes the ruby tones glow even
more brightly. Loved by bees and full of summer energy, this is a small plant with a
big presence.
Thanks to its naturally compact habit, Penstemon Rock Candy in Ruby is ideal for
the front of borders, rockeries or patio containers, where its colour and form can be
fully enjoyed. It pairs beautifully with softer tones like silvers, pinks and mauves, and
adds depth and structure without taking over.
Plant in well-drained soil in a sunny spot. It enjoys regular watering in dry spells but
dislikes sitting in wet soil over winter. Deadhead spent blooms to keep flowers
coming, and in colder areas, a light mulch in autumn will help protect the roots.
With its glowing ruby colour and elegant white-throated blooms, Penstemon Rock
Candy Ruby adds a splash of charm and long-lasting beauty to any space.
