What are a few flowers that have beautiful scents?

roses, orange blossom, wax flower are some of my favorites
Some people love the scent of lillies but others think they stick so watch out on those.

Beautiful scent is very dependable of what you like. Personally I like lavander and gardenia.

There are several different types. The strongest and most fragrant is the moon flower that only blooms from 5pm until about noon the next day. Go to a web sites on plants, which they are MANY good ones, and look for plants by scents. I have many plants that smell good such as lavender, roses, magnolias, etc. Also try herbs. They are very fragrant, usually more so than floral plants. I love to smell the fresh thyme, spearmint, rosemary, etc. Also, go to a greenhouse and sniff around. It’s free and you can get the ones you like best.

You have to be more specific in asking a question like this. Do you want flowers with beautiful scent to add in a bouquet or basket to be delivered to someone, or do you want to plant them in your garden. Or perhaps you may want to start a line of perfumes and are doing some research for beautifully scented flowers that people like or to discover some of these flowers from others. Or perhaps you may want to wear them in your hair if you are a female to to give to a friend as a pot-pourri. Maybe you could be helping your child to do his homework and he has to have a list of names of nice scented flowers for his assignment.
It is difficult to help when I do not know where you are from as different countries and different parts of the world have different species of flowers. In my part of the world, I would recommend the jasmine, the gardenia and the frangipani.

Carnations, Lilliums. Roses, Gardenia, Some species of Orchid, Sweet Peas, Some species of Petunia, Jasmine, Sweet Williams,Lilac,Lavender,Dianthus, Mexican Orange Blossom, Some Rhododendron species,Frangipani. Daffodils, Daphne.

One flower that has a beautiful scent are the roses or sunflowers, but the best smelling roses are the candy cane roses.

White flowers generally have strong and beautiful scents. Hyacinthus, white lilacs, white lilies, Jasmin.
I also like the lightness and reshness of stockflowers and freesias, whatever the colour is, their scent is refined and light.

i lke lilacs the best. but roses are nice, too.
