I recently purchased a Sundew and for the first 2 or 3 weeks it looked fantastic with bright red coloring and lots of mucilage. Then it started to flower and the plant itself started to look pretty sickly. I have been following all the care directions- filtered water, bright sun, moist soil- but I cannot seem to return the plant to its former beauty. Is this normal for the plant? The flowers never seem to bloom but they appear healthy other wise. Any advice?
