Silene is a genus of flowering plants in the family Caryophyllaceae. Containing approximately 700 species, it is the largest genus in the family. Common names include campion (which is shared with the related genus Lychnis) or catchfly. Many Silene species are widely distributed, particularly in the northern hemisphere.
Silene can be annuals, biennials or herbaceous or evergreen perennials, with opposite, untoothed leaves and solitary or clustered flowers with 5, usually notched petals. Some species of Silene stand erect - others are spreading or cushion plants. The stems often are covered with a sticky material to which insects may adhere—hence the common name for the plant. The smooth-edged leaves are arranged opposite each other on the stem. The fruit is a capsule. Some species have solitary flowers - others have branched clusters of red, white, or pink flowers.
Plant preferably between September and the end of November or between March and the end of April, when the winter reserves are formed and the temperatures are not too low.
Bury the roots a few centimeters so that the foliage is flush. Fill and pack well around the plant so as not to leave a pocket of air.
Water copiously just after planting.
If you are planting in a pot, use one whose volume corresponds to that of the plant, otherwise you will have to water it too often. You can use gravel at the bottom under mixture of soil, compost or compost for better drainage.
Water my campion
Water regulary in the fist weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top of the soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
