Thanks everyone for the encouragement
Leptotes bicolor has done exceptionally well for me in water culture. The above photo is after almost 2 years in water culture. It had 12 flowers in slightly overlapping sequence covering 6 weeks.
If you are interested in lookin at the method I use for water culture I have several posts where I had the time to explain it in more detail. If you have questions after reading these, pertaining to your projects I will be glad to try to answer them.
I would start with
Onc. Sharry Baby in water culture
