I bought this plant in November of 2014, it had 3 blooms that were almost faded. I got 7 new buds in March and this plant has been in bloom since then. Four of the flowers faded when I went on vacation, but it is still in bloom with 3 flowers! If you can grow this plant it is highly rewarding because it stays in bloom for so long.
Mine grows in a southern facing windowsill. I don't really do anything special.
