Va Blue Bell

Question

I planted a Virginia Blue Bell several years ago. It comes up and blooms each spring, but never spreads. It is planted under a big oak tree with mostly shade. What could be the problem?
Thanks;

Answer 1

Partial sun to full sun may be a better match for the Virginia Blue Bells.
You should see this plant naturalizing in your landscape.
