I will always wait for the blue violets to grow in my yard. I do not have regular pruned grass; I just let it grow and mow it. In early spring, the wild violets congregate in my yard in various locations. Sometimes, they appear in one place in the front or backyard and sometimes in surprising places in the yard where I would not expect them. I like them; they would be unwelcome in a yard treated with chemicals. I just consider them to be gifts from nature.
Science gives them the name, (Viola odorata). They grow in groups of heart-shaped leaves with beautiful blue flowers that just are so delicate. They continue to seed, low to the ground. What seems to be dead flowers really are the flowers reproducing seeds. I noticed after mowing, they continue to grow. The seed is spread so easily that they can get transported all over the yard.
If you do not have a treated lawn with chemicals, an added feature of violets is that they are good for food presentations, and both leaves (heart-shaped), flowers, and stems are edible. I like to include the flowers on desserts or in salads to add that wild touch. This is also a plant you could pot grow, especially if you treat the yard with chemicals or have pets in the yard.
I hope that your yard gives you a treat with these beautiful wildflowers.
