Answer: Based on your description I am not sure what is wrong with your plant. Anthuriums are not easy to grow, especially during the winter heating season! For their ideal conditions, think "jungle". They need bright light in winter, with a minimum temperature
of about 65 degrees (warmer is much better), and bright but not direct sun in summer.
They are humidity-loving, so in addition to the pebble tray you might try running a humidifier. Water lightly every few days with tepid water and
mist frequently when humidity is below 50% (it can approach 10% in your home in winter!) . I hope this helps.
