Dog Flower like many garden flowers, have a long history of enjoyment. Children love opening the jaw of the flower and watching it snap shut. Opening the dog’s jaw in just the right place is a skill passed down from parent to child just like the love of gardening. Dog flowers are available in every color but blue. They are, in botanical terminology, zygomorphic, with assymetrical petals, and stamens and stigma enclosed between the two petal lips comprising fused petals.
