| Any Tuberose, either the single or the double but the singles do have a deeper scent. Nicotiana sylvestris...the original flowering tobacco. Bushy plant about 2 feet across with broad leaves. Long stalks shoot up about 5 feet and are full of super fragrant, brilliant white flowers. It even acts like a evergreen here unless it gets waaay cold. Heliotrope Marine, try to find the taller cultivars and you will be thanking yourself all summer and fall. Great smelling plant....even the shorter ones! Confederate Jessamine....some call it star jessamine. Cannot be beaten for pervasive scent all day during spring and early summer. A true "what is that smell" plant... I do not know the name...it's call sweetbox. This shrub will absolutely embarrass you. I walked around the garden shop for 25 minutes looking for source of the grandiose odor that just made me nuts. Small...itsy bitsy flowers at the internodes and has nice dark green foliage to boot. Moonflower...great night fragrance and well into the cool summer mornings too....I love my java, newspaper and a moonflower. Gardenias, what can be said, as is the same for Magnolias. My personal favorite is the double petunia. I grow mine from seed and the purple piroette variety is just grand. With that said, petunias are unbeatable for quick color and fantastic frangrance. Just keep em ferted..... I think that bout covers it.....albeit these are just a few, asides this is this longest reply I have ever let loose here.....whew! |
