Q.balloon flower color change
Blue balloon flower suddenly has white flowers where I planted seeds from mother plant. I carefully collected seed pods from mother plant and planted the seeds nearby. The new plants have blue flowers and just a few white ones. I am wondering where these white flowers suddenly come from. There are no balloon flower plants nearby.
The plant you collected the seeds from was likely a hybrid. The seeds may not be the same as the mother plant.
