My Favourite Blue
It has been a long, frigid winter and many plants have perished in the greenhouse on the coldest nights. However I was thrilled to see that almost all my clematis cuttings and seedlings have survived, despite being left on one of the coldest areas of the greenhouse.
Among these are several cuttings I made last year of a plant that I grew from seed that was collected from Clematis 'Helsinborg'. When it finally flowered it turned out to be coloured a very lovely clear blue, quite unlike its parent which is described as having slightly twisted tepals and, together with its steminoides, coloured a deep purple or mauve. C. 'Helsingborg is a cross of C. ochotensis and C. alpina and it looks was if "my favourite blue" has inherited its form from its alpina parent. Blue tepals with white staminoides are also common in C. alpina.

Hmm? I wonder if that perfect blue clematis would like to grow in a container on my balcony?

Elke, It's worth a try!
Thanks. Would love to try; i enjoy growing clematis in my little garden. I live in Toronto so could pick up some time.
