Also known as C. ‘Sieboldiana’, this plant was introduced by Dr Philipp von Siebold to the Leiden Botanical Garden in Holland and then to the British Isles in 1835. This unusual clematis has a flower that resembles a passion flower and is much sought after. The habit is similar to C. florida and C. f. Plena. The 10 cm (4in) diameter flowers have 6 creamy white outer tepals in summer, creamy green in autumn, which are overlapping to make a fully rounded flower, especially as the tips of the tepals recurve back. The outer tepals are offset by a dramatic central boss of purple petaloid stamens about 5 – 6 cm across, which remain for a week after the outer tepals have fallen away. The flowers are sterile but the plants sometimes revert to C. f. Plena.
Flowers: early summer to early autumn outside, under late autumn under glass (UK)
A splendiferously colored Eastern China native. It provides a radiant show of 4-inch flowers with creamy white sepals and large, full, bursting center domes of rich purple stamens, brushed ever so slightly with pale lime green.
