African violet

My all African violets were wiped out by unknown virus or pests last year. A few leaves were saved and propagated.  Months ago, I found one of the baby plants got sick, unknown disease, so I placed it in a plastic bag as a makeshift smoke chamber, let it bathing in the smoke by burning a pc of mosquito repellent incense about 30 minutes. It seems cured recover afterwards.  And keeps growing and flowering.

I took the same method for others when they got sick.

This African violet's flowers will drop down the linked petals with anthers in one pc when the flowers faded, that I gather why they are so named FallingRainDrop.
