Spider mites are common to indoor anthuriums grown in too wet conditions. Nitrogen is a particular problem; in addition to potential leaf burn, nitrogen encourages abundant leaves, but inhibits flower production when applied in excess. Each flower can last for about six weeks, and they may return, flowering every few months. Keeping and caring for anthurium indoors is important because the plant can't withstand temperatures much cooler than 60 degrees Fahrenheit. Diseased plants (Fig. HortScience 39:1327-1331.
