    Hi Monica. I bet you did come across a Rhododendron occidentale (Western Azalea) at the Lake Wilderness Arboretum. A few species of Rhododendron are fragrant, including our native species.

    I recently walked through the Lake Wilderness arboretum and instantly was met with a very sweet fragrance. I found out that I was smelling the blossoms of a rhodie or an azalea but I have never ever been near one that was fragrant. It looked similar to number 2 in the photo in blossom color. A taller shrub maybe 6-7 feet tall with limbs spaced pretty far apart… can you help?
