I understand your Freesias are hybrids. They have a nice scent, but not as strong as the sp. Freesias have. If you want to compare, you can let a few of your blooms go to seed and sow them (they are quite easy). The resulting plants will revert to the species (smaller plant, a bit smaller flower, and a scent you can notice from farther than the hyb.). The flowers will all be creamish white with some yellow.
