Lovely fragrant oils can be made from your garden flowers. If you are just after a fragrant oil, it’s pretty easy. Simply add the flower petals to your (low scent) oil, soak for 24 hours then drain.

After that you’ve got steam distillation, other solvent extraction, expression, sieving, or enfleurage. This is more complex chemistry and requires some skills and equipment.

Solvent extraction is the easiest. Many flowers have enough volatile oils to use oil extraction. Others with delicate scents and low oils may be more suited to steeping in alcohol.
