When I visited in 2010 Plantarium in Boskoop I saw a clematis with a special color and the plant was not so high. The plant had a Bronze Medal. The flowers looked similar to the flowers of Clematis × durandii. The plants looked very healthy and very full of flowers.

Clematis 'Zomisri' MISSISSIPPI RIVER is a clematis raised by Wim Snoeijer in 2004 and registered in 2010. This clematis was introduced in 2010.

C. 'Zomisri' MISSISSIPPI RIVER grows up to 1.5-2 m and has integrifolia blood. The flowers are 6-8 cm in diameter with 6 glossy sepals. Initially the flowers are half-nodding. The color of the flower is dark violet with a purple tint when open. The flowers have violet stamens with very striking gold-yellow anthers.

The flowers appear from June to September on new growth. This clematis has a lot of flowers during the flowering period. The plant grows well in a sunny or a half-shaded position.

The pruning group is 3 and therefore you need to prune the plant in late winter or early spring, possibly even later in the season depending on when spring arrives. Hard pruning keeps the plant in a good condition and encourages rich flowering.

Because of the special colour inside and outside the flowers of this clematis, it can be used very well with garden plants. This clematis is not useful as a climbing plant but should be grown in the border. Combinations with garden plants and small shrubs are the best for this kind of clematis. In this situation the flowers are most noticeable. The size of the plant is not too large and therefore the plant can also be used in a pot. I have had the plant for a long time in a pot on the terrace and all the time it has had a lot of flowers. This clematis is very useful as pot plant is my experience.

C. 'Zomisri' MISSISSIPPI RIVER is hardy in zones 5, 6, 7, 8 and 9.

The plant needs good soil and during spring and summer, enough water and nutrition. During winter the plant likes a place where it is not too wet. If you have the plant in a pot then you must give the plant good attention for watering and feeding. Do not place the plant in pot during winter in a too wet position.
