That was the same with Grandma. Always beautiful lilacs from Grandma! That is pretty amazing with the bleeding hearts for 45 years! I am sure new seed is involved, but, it is still related! You cannot take that away from it!
I had no idea you could do that with lilac and violet. I know nothing about tincture.
I am still learning about the tinctures as it can be a bit overwhelming learning all the different uses.
