Just wait!

The flowers with petals (chasmogamous) will come in the spring. What you notice now as precursors to the pods are the petal-less flowers (cleistogamous). Day length is a key factor in determining which type of flowers violets produce: long days lead to cleistogamous flowers.

Alternatives to waiting 7 or 8 months:
- get yourself a time machine,
- head for the southern hemisphere in a month or two.
