Lasurstern Clematis:

Lasurstern Clematis is a truly exotic looking clematis, with its enormous flowers reaching up to around 25cm in diameter and covering the plant from May to June and then appearing again when the plant produces a second flowering flush in September.

Lasurstern produces blooms that are an exquisite shade of clear lavender blue, with deep pleated midribs and crimped edges. After the show of flowers the large lime-yellow anthers remain to produce an attractive display of seedheads through the autumn and into winter.

Great for your garden:

Lasurstern is a perfect clematis to climb over smaller structures such as trellis or pergolas where it looks particularly good when grown with complimentary coloured roses. It is also vigorous enough to grow through trees or large shrubs.

Lasurstern was awarded the RHS Award of Garden Merit due to its brilliant performance and easy of cultivation.

    Lasurstern was bred by Goos and Koenemann, a renowned German nursery and clematis breeder, in around 1905. Max Goos and August Koenemann were great friends who shared a delight in plants and flowers. They made many contributions to the plant world, but are best known for their work on breeding Irises. They are credited with bringing to market some of the best loved Irises, and won many awards and accolades throughout their working lives.
