Hello one and all,
this is my first time on any forum site, but I come to you needing help! I'm a newby to houseplants, but have always loved and admired them. I bought myself an Ioxora (name on the care instructions) and everything was going fine 'til I went away for chrsitmas and left it in a wee bowl of water so it didn't dry out (as directed in the crare instructions). I am now back and find it's leaves are starting to drop and go a bit dry (a paler shade of green) looking around the edges, yet it was kept watered whilst I was away by the landlady.
I have posted (with any luck) a photo of it, and hope someone can help me. (I also have another plant that is in the same situation, a calendiva... it's not dropping leaves but was left and now the stems seem a bit sodden)

Just so I don't feel bad coming to you all only for help! I hope over time I too will be able to offer advice and knowledge, but I'm new to all this... my room at Uni didn't allow for plants as my new place does.

Happy new year
WildRose
