I let the violets spread when I first started gardening here. Eventually I had to make a decision, and out they came. I loved those little johnny Jump Ups that seemed to come on their own and even added in some beautiful apricoty orange ones. I seem to remember that they didn't come back, at least not like those little purple and yellow Johnny Jump Ups! Now I am planting for the birds, bees and butterflies. Perhaps time to see if any violets will fit the bill. Thanks for an interesting article!
