A few months ago, I bought a White Queen (EK-Belaia Koroleva) African violet. It's the prettiest African violet I've ever owned. I love the shape of the large double flowers and the way you can see most of the stamens, sunken right in the middle of the thick, ruffled petals.

My question is this: what other varieties most closely resemble the White Queen, but have [solid] colored flowers? I'm looking for non-variegated varieties. Any color would be great.

If it's a variety I can easily buy online, that's even better.

Thanks!
