Arguably my favorite clematis.

Vigorous, hardy, floriferous, long-blooming, and (like all viticellas) resistant to clematis wilt. The flowers are intensely colored, and the pale centers make them jump out visually, especially when in shadow.

I planted my plant in the shade and it bloomed. I transplanted it into the sun and it responded positively. I have a pink and purple vine.

I love this clematis. I have only had it for 1 year but it bloomed well and grew up to cover the arch over my gate. It threw a few flowers all summer long before the bigger flush of bloom in late summer. I had mildew problems with my Rugoochi but this one remained healthy. The purple stamens are exquisite. This is one my favorite plants in my garden, it makes me happy every time I walk out on my patio.

This is one of the most distinctive viticella selections. The flowers are white in the centre of the tepals but become quite purplsh-blue along the margins...wonderful two-toned effect. The flowers are the largest of any viticella (4" across), approaching the size of C. jackmanii. Very free-flowering. This selection was raised by Lemoine of France in 1884.
