I've always assumed the ones I have always had were American, as they grow wild out it the woods and on the roadsides in south AR. Maybe they aren't but they smell great.

I have an Amethyst Falls but it has no scent. I thought that maybe it was just me that couldn't smell it but nobody has detected any smell and it's definitely an Amethyst Falls.

The ones seen growing "wild" are most likely escapees of the Asian varieties, both of which are considered invasive species in parts of the country. And both of which have a lovely, fragrant aroma whern in bloom. Wisteria frutescens, our native species, is much more well-behaved but has a distinct aroma some find mildly to distinctly unpleasant. Plant scent is very subjective so what may offend one may not offer any scent or actually smell pleasant to another.

Odd so many plants can produce an aroma like cat pee - juniper tams are known for it as are certain species of boxwood. And apparently Amethyst Falls wisteria, too!!

Mine smells like cat pee but only if you actually stick your nose in the bloom. Otherwise, they are great vines. If they are outside, I don't think you will notice the smell.

Mine smells like the old fashion rose scent that the old ladies doused themselves with. Just a musky, floral odor that immediately takes me back to when I laid down on my grandmother's carpet as a young child. My wife likes the smell, I'm sort of neutral.

It took me 3 years to train mine into a 6-foot tree form and it died this winter. :(

Oh well, but back on topic ... sometimes the flowers smelled really sweet and grape-like and sometimes they smelled like cat urine. Go figure. If I remember correctly, they smelled sweeter and more pleasant when they were young and began to smell poorly as they aged.

This year I'm going to try again to form a Wisteria standard, but I'm using Wisteria macrostachya 'Blue Moon'. It's supposed to be more hardy, but like Amethyst Falls it's not crazy aggressive. Also, the flower panicles are longer (about 1 foot) and it supposed to repeat bloom at least 2-3 additional times through the season.

Wish me luck!

I've got a 5 year vine of Amethyst. It's almost my favorite plant in my yard. The plethora of blooms...poetic.

That andwers my question. My beautiful Wisteria has started to make the in doors of the bedroom it is near smell of cat urine ! Ugh! It is horrible. Now not sure what to do about it. Obviously getting old.
