• Light requirements : Requires full sun to maximize flower production and intensify the rich petal coloration.

Use

• Types of use : Ideal for injecting bold colour into sunny flowerbeds and mixed borders, or creating a high-impact focal point in patio containers and balconies. The magnificent blooms also make superb cut flowers for summer bouquets.
• Ornamental benefits : Delivers a warm, striking colour contrast that immediately draws the eye, maintaining a dense and tidy structure all season long.

Maintenance

• Watering : Water regularly during the establishment phase and increase frequency during hot summer dry spells. Allow the soil surface to dry slightly between waterings to prevent excess moisture.
• Fertilization : Incorporate a slow-release granular fertilizer at planting time or apply a water-soluble liquid fertilizer for flowering plants every two weeks to sustain continuous bud production.
• Pruning : Snip off faded flowers to stimulate a cleaner look and encourage fresh buds, though the plant will keep blooming heavily even without intervention.
• Planting : Install after all danger of spring frost has passed, keeping an approximate 50 cm spacing. Dig a hole slightly larger than the root ball and amend the soil with high-quality compost.
