Hypericum perforatum: Yellow flowers on muti-branched plants. Flowering tops are medicinal. A nervine, anti-depressant, anti-inflamatory. We like to soak the blossoms in olive oil. Watch it turn red. Makes a lovely massage oil. Memories of past summers. Prefers poor quickly draining soils in full sun. Needs light to germinate, so sprinkle on a sandy soil surface. Plant outside 60 cm (2 feet) apart. 0.03g/Approximately 200 seeds
