A true eye-catcher. Which is very winter-hardy. The forest vine 'Rouge Cardinal' (Clematis) has an abundance of flowers. The large-flowered 'Rouge Cardinal' has beautiful dark red to deep purple-red flowers. With a velvety glow. With a diameter of 13–18 cm! The flowers bloom in the spring. Often with a slight follow-up bloom in autumn.
Tie up the forest vine well during the growing season. Only prune when a tangle of stems has developed. Prune it after flowering. The clematis likes to have its crown in full sun The roots, on the other hand, like to be sheltered. So make sure that there is always something growing in front of the plant that provides shade and coolness. The soil should be kept slightly damp. Give it extra water during dry periods.
