Capers are a rich source of rutin, a bioflavonoid that is sometimes taken in supplement form to prevent and treat varicose veins. Capers can be grown easily from fresh seeds gathered from ripe fruit and planted into well drained seed raising mix. Seedlings appear in two to four weeks. Old, stored seeds enter a state of dormancy and require cold stratification to germinate. The viable embryos germinate within three to four days after partial removal of the lignified seed coats. The seed coats and the mucilage surrounding the seeds may be ecological adaptations to avoid water loss and conserve seed viability during the dry season.
