While violas will readily reseed in the garden I wanted to collect seeds from my Viola 'BlackJack' blooms as a backup because I was growing them in a small terracotta pot on my porch garden. Before I could collect seeds I had to make sure the blooms were pollinated. The tiny blooms on these plants made finding the right tool difficult, artist brushes were too large so I ended up using a hair from my beard. Yes, you read that right. It seems like a lot of trouble to go through for a garden annual but the seeds for these violas were kind of expensive.
