Hi Donna. Ideally, a healthy anthurium should produce a flower for every new leaf. They appreciate a south window in winter. Resist the urge use granulated plant food right now as they are sensitive to potent fertilizers and burn easily. I use the Miracle Grow Orchid Mist during winter. Just mist the plant lightly once a week. I have about 25 of them and they bloom as well in winter as in summer.
You might want to move your post to the tropicals or indoor gardening forum so that more people see it.
Good luck! They're my favorite plant!
