Viscaria 'Plena'

(syn. Lychnis Plena)

Product Image
This compact, modestly short-lived (3-4 years) tufted perennial produces narrow, dark green leaves and sticky, upright stems that support vibrant, fully double magenta-pink flowers from early to mid-summer. Known as 'catchfly' due to its sticky sap, which traps insects, Viscaria vulgaris 'Plena' offers long-lasting blooms that appear in narrow panicles, adding a striking pop of colour to the garden. Ideal for well-drained soil in sun or part shade, it works well in borders and is great for cutting. The compact growth and abundant blooms make it a standout choice for adding structure and colour to mixed planting.

How to care for Viscaria Plena:

Viscaria thrives in well-drained soil, preferably in full sun or partial shade. Plant in a location where it can receive at least six hours of sunlight daily for optimal flowering. Before planting, enrich the soil with organic matter to ensure good soil health and improve heavier or lighter soils. Once established, this hardy perennial benefits from regular watering during dry spells to keep the soil consistently moist. Deadhead spent flowers to prolong blooming and trim back the plant after flowering to encourage a tidy shape and prevent self-seeding. In late autumn or early spring, cut back the foliage to encourage fresh growth for the following season. Adding a layer of mulch around the base will help protect the roots in colder climates and retain soil moisture.
