I have this window spot needing a lush, bushy houseplant. The houseplants forum suggested an AV. I know absolutely nothing about African Violets. I'd like a larger plant, do any grow wider/taller than 18"?? It's a south-facing bay window. Room stays around 68 degrees, I'd say. Heater/AC vent right under table probably balances cold from window and heat from duct in winter and vice versa in summer. Also, tips on growing the type you suggest? Thanks!
