Violets bloom in spring in your yard and if you have shady places they can bloom all summer. Both the leaves and the blossoms are edible and useful medicinally. So the other morning we went out and picked wild violets growing in our yard. NOTE! Only pick from areas you know were not sprayed or treated with chemicals!
Here are a few links to pages on the uses of violets and different ways to process them. I dried the leaves for tea and then used the flowers for making violet soap. You can also eat the flowers in salads and use them on cakes if you Candy them.
I also love the scent of Violet Perfume. It is perfect as a first perfume for a young girl who is old enough for a perfume but still young. Here is a Violette Perfume from Amazon that has great review.
