What has been your experience with Clematis terniflora?

Spring Hill, FL(Zone 9a)

Will anyone who's grown Clematis terniflora, common names Sweet Autumn Virginsbower, also Thai Clematis (and possibly others) tell me what your experience has been? Is it a garden thug that will make you curse the day you decided to plant it? Have your neighbors cursed the day you planted it? Has it been reliably fragrant? Does it need strong support? Does it wrap up it's support so tight that it is a dreaded chore to prune? Is it just a vigorous vine that plays nice with it's garden neighbors as long as it's been given needed space(a bad rep from mistaken ID with other vines)? A pain in the ... but worth it for the fragrance? How much- and what- care does Clematis terniflora need? Please share your experiences, good and bad, with this vine. I'm all ears. Well, actually eyes. You know what I mean.

Sorry I have not grown it but I am thinking about it.

This deciduous, late-flowering twining vine with deep green leaves and profuse, fragrant white flowers is easy to grow and will thrive and bloom in shade. Star-shaped blossoms are 1 inch across, appearing from late August to October and maturing to attractive, plume-like seed heads. The shiny green foliage is leathery.
Noteworthy characteristics: Can self-seed invasively and has escaped cultivation and naturalized in the East and Midwest US. Without support, it will sprawl along the ground, covering up to 10 feet and choking most weeds.

I'm in borderline zone SW 9b/10a too cold for Mangos too hot for clemaitis. I had sweet autumn clemaitis in Chicago. I absolutely loved it! Never a thug. Has anyone grown it in my zone?
