Description
Lychnis chalcedonica puts on quite a show, adding height and vibrancy to the summer garden. Clusters of scarlet, star-shaped flowers are borne atop tall, stiff stems from June to July. Commonly known as Maltese Cross, this hardy perennial holds an RHS AGM for its garden performance. Thriving in damp, boggy environments, these pretty plants make a fine addition to bog gardens and the edge of ponds and streams. Height: 120cm (48"). Spread: 30cm (12"). Sow Lychnis seed indoors from February to April. Sow seed on the surface of a good quality seed compost and gently firm down. Seal seed trays inside a plastic bag or place in a heated propagator at a temperature of 19-24C (65-75F). Do not exclude light as this helps germination, which usually takes 10-20 days. Keep the compost moist but not saturated. When seedlings are large enough to handle, transplant and grow them on in cooler conditions until large enough to plant outdoors. When Lychnis plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days. Transplant outdoors in a sunny or semi shaded position on fertile, well-drained soil that remains reliably moist in summer. Also suitable for clay soils, damp or boggy areas and planting around the edges of ponds. Seed sown in February will often flower the same year.
