Brighten your landscapes with this horticultural gem that deploys a deeply vibrant ruby-red flowering. The Summit Sweets™ Ruby Penstemon captivates the eye all summer long, erecting magnificent floral spikes that energize garden beds. This robust variety resists heat remarkably well and brings an irresistible touch of architectural elegance to sunny spaces.
Characteristics
Foliage : Deploys dark green, glossy, lance-shaped leaves. This deciduous foliage forms a dense, healthy, and vigorous clump that beautifully highlights the brilliance of the flowers.
Flowering / Stems : Offers large, tubular, bell-shaped flowers of an intense ruby-red with a lighter throat. The rigid and upright floral stems rise proudly above the foliage from June until the first frosts.
Light : Requires full sun exposure to maximize the abundance and brilliance of its flowering.
Habit : Presents an upright, compact, and well-bushy habit, ideal for structuring the middle of flower beds.
Growth : Displays rapid growth, reaching a maximum height of approximately 45 to 60 cm and a spread of 30 to 45 cm.
Soil : Thrives in light, loose, and above all perfectly drained soil. It tolerates sandy or rocky soils and dreads stagnant moisture in winter.
Temperature : Displays excellent hardiness in zone 4.
Resistances : Demonstrates superb tolerance to intense heat and temporary drought once well established. It naturally resists attacks by White-tailed deer.
Use
Types of use : Beautifully structures mass plantings, the middle of flower beds, and sunny rock gardens. It also integrates perfectly into a large container to color a terrace or a balcony.
Decorative advantages : Creates a striking color contrast thanks to its theatrical red. Its vertical spikes bring relief and movement, while its flowers make excellent cut flowers for fresh bouquets.
Maintenance
Watering : Water regularly after planting to promote rooting. Allow the soil to dry on the surface between waterings thereafter, as this plant prefers a rather dry environment over too wet.
Fertilization : Apply a rich compost or a balanced granular fertilizer in early spring to support flower production.
Pruning : Prune faded floral stems as they go to stimulate the appearance of new waves of flowers. Cut the foliage completely back to the ground late in autumn or early in spring.
Planting : Install the plant in spring in a hole twice as wide as the root ball, taking care not to bury the crown. Space the plants 35 cm apart to allow them to develop harmoniously.
Winter protection : Apply a mulch of dry leaves or straw in autumn to protect the rootstock from winter temperature fluctuations, especially during the first winters.
