I have no idea what wisteria/blue rain smells like IRL.
But this candle smells fresh, mysterious, vaguely sweet and "floral" at the same time, with a hint of old-fashioned "soap" tone.
The result is a nostalgic and slightly magical scent that is soothing and sparks the imagination.
You can blow out the candle after a couple of minutes, and the light will still project for a LONG time after it’s out.
If you have a few strategically placed around the home, you can keep the scent alive for a long time without lighting them very often.
The scent is not overpowering and is not headache-inducing, IMO.
This is my favorite scented candle, I have bought many of them and I hope they come back again.
"Daylight Wisteria" is the "blue prescription" for sweet mysterious dreams :)
