Climbing hydrangea doesn't get much of a mention as a fragrant plant, but the scent is nice and wafts. Mine is blooming now and my front porch is heavenly!
I have one that I've been babying for 6 years now. First I planted it in the wrong spot. After the 2nd years of not growing I moved it to a better spot. Then two years later I moved to a new house and took my climbing hydrangea with me. It didn't take the move very well and now...a year and a half later...it's finally starting to recover. I'm pleased to know that it will reward my efforts with a fragrance.
Is there a name for your plant. I'm looking for something to plant between my neighbor and myself and promised her it would be fragrant as well as a screen for the small area we want to enclose. Thanks.
