Gardeners' Notes:

This is a beautiful two-toned (white inside, purple outside) clematis that starts blooming in June for me in Colorado. My clematis does well in dappled shade.

Arguably my favorite clematis.

Hardy to Z4.

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.

Flowers are large for a viticella, open flat, and face upwards, but are decidedly smaller than 'Jackmannii'. There is 25% C. florida in its ancestry.

The Royal Horticultural Society has given this cultivar its coveted Award of Garden Merit.

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 clematis is an heirloom variety first introduced by Victor & Marie Lemoine of France in 1883. It blooms heavily from July thru October in my zone 9B.

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.
