SILENE 'PURPLE PRINCE'
We have finally succeeded in producing a purple-leafed, fertile 'Red Campion' (Silene dioica). The leaves of this superb new Plant World discovery start off green when young and most go darker the brighter the sun is, giving a perfect foil for the bright pink flowers. A small percentage will stay green and can be discarded.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
