My sister bought 3 passion flower vines...red, white and blue. She planted them in the same flower bed. The blue has bloomed, but she lost either the red or the white. She doesn't know which one. The blue blooms, but the remaining one drops its buds before the bloom opens.
Any suggestions?

Bud Drop Question
Mine do that when there's a great difference in the weather conditions from one week to the next, such as too humid and hot (cooks them) or too windy and dry (turns leaves and stems to fine paper). I also keep an eye out for mealy bugs and spider mites. It seems it's always something or a combination of weather-related factors and insects that can cause this malady with my plants.
