Flowering time is generally early summer. Pruning is undertaken in winter and involves the removal of dead stems and reducing the specimen to its base.
Regular feeding during the growing season and summer months with a long term blood and bone and sulphate of potash mix (10:1) + foliar feeding using for example Powerfeed or a mix of Powerfeed and seaweed solution (3:1).
This is more a trailing plant than a climber with flowering stems reaching 1.4m to 2m in length. Rather than letting it trail along the ground and not see it in flower, we have opted for the plant to be contained within a triangle of bamboo stems; thus creating a living focal point. Flowers are terminal, single and white.
From our research it appears that C. mandshurica was first mentioned in the mid 1800s by F J Ruprecht (1814 -1870). FJ was an Austrian born physician and botanist who spent a considerable part of his life based in St. Petersburg Russia and undertaking many plant hunting expeditions to eastern Russia, including Alaska which at the time was still part of the country. Alaska wasn’t purchased by the USA from Russia until 1867.
