Clematis ‘Diamantina’ (Evipo039) has luscious, deep violet blue double flowers that grow to a whopping 15cm across. The blooms open from late spring with a strong repeat showing of double and single blooms in autumn. Each flower can last up to four week, which is quite a feat with such delicate petals.

The flowers of Clematis ‘Diamantina’ can even be used in cut flower arrangements. It is pruning group 2; you just need to cut it back to a third late winter/early spring.

Clematis ‘Diamantina’ is part of Raymond Evison’s prestigious Regal Collection. The flowers may be single while establishing and when they rebloom.

Clematis generally grow well where Roses grow well, and they are also excellent in combination. You can use similar colours for a lovely blend, or create some drama with complimentary shades. In fact, Clematis intermingle well with many different plants – trees and shrubs especially as they can be used for climbing in a beautiful symbiotic way. They really are versatile, and what’s, more, you can grow them in pots.

The old adage is to plant your clematis so their 'head' is in the sun and their 'feet' are in the shade. In other words they like their root zone to be cool and protected, and the stems to grow up into the sunshine. You can protect the root zone with mulch and/or by using other plants to shield them from the sun.

Grow Clematis in humus rich, moist, well drained soil. They need good drainage, or the roots can rot. Plant so they will receive around six hours sun a day and are shielded from the hot afternoon rays.

To perform at their best they should be fertilised well, to do this you can use a Rose Fertiliser every three months or so when they are actively growing.
