Clematis identification

Question

I once owned a Polish clematis which changed name approx 10-12 years ago & since moving to Scarborough would like to obtain again. Unfortunately I only know it by it's old name which I can only spell phonetically - Maximawenya?

It's a very vigorous, white plant, late flowering. Hope you can help?

Answer 1

The clematis you describe is probably the sweet autumn clematis which is sold as C. maximowicziana, C. paniculata and C. dioscoreifolia and is also remarkably similar in habit and appearance to the better behaved Clematis ligusticifolia 'Prairie Traveler's Joy' and Clematis mandshurica.

• hardy from zone 2 up
• fragrant autumn bloomer with small cruciform pure white flowers
• climbs at least 20 feet (~6 m)
• medium well drained soil and tolerates shade
• aggressive self seeder which has escaped cultivation in the US Eastern and Midwest

Answer 2

This isn't really an answer as such, but there's too much to ask to put in a comment. Phonetic spelling of the name isn't much use I'm afraid. You've said its late flowering and vigorous, so its likely a Prune group 3 or viticella group type, but it would be helpful if you could describe the flowers and foliage. For instance, were the flowers very large, or were there lots of small flowers? What colour were the stamens in the centre? Were the flowers double or single? How vigorous was it in terms of height and spread, around 15 feet or 35 feet high? was it deciduous or evergreen?

There are hundreds of varieties of clematis, so this extra information should help to narrow down the field, so please edit your question adding as much information as possible.
