I brought my hanging scarlet begonias in for the winter
By Jsnik
United States 
They are doing great, even blooming a little, a little leggie- but they now have tiny little hard crystals along the edges
of every leaf- they feel hard - are beautiful- but with so many plants & pets in the house just curious what it is
and if it's bad- Thanks!

Some plants excrete gum or watery liquid from their leaves.This is nothing to worry about.
