The Common Rockrose is an evergreen, trailing plant with bright yellow flowers and orange stamens. Excellent for the sunny and dry areas of the garden, rockeries, screes, xeriscaping. A cheerful and easy plant. Also, a great provider of nectar for bees and food plant for a few species of moths and butterflies.
Germination: sow in the spring like for any easy germinator; seeds are usually slow to germinate, between 1-3 months. Maybe scarification could improve the germination.
