I love gardenias and magnolias. I have a magnolia tree in my yard and I'm always so excited to see it bloom with it's gigantic flowers! They have a subtle smell, but it's lovely, especially around dusk. And gardenias I have always loved the smell of. I have a potted gardenia bush I've been tending for about a year now. I can't wait until it blossoms! We have a lot of star jasmine in our neighborhood that is very fragrant this time of year as well.
My favorite flower has always been carnations. Pink, red or white I love how they smell! I actually grew some here in Texas years ago, then the rabbits found them! Apparently they are just as tasty as fragrant
Petunias are my favorite flower, just love all the color varieties and their smell. Both of my grandmothers loved growing things, mostly roses and I love those too, but they each gave me reasons for loving different ones.
