Last fall I bought 6 amaryllis bulbs to grow for the holiday season -- one of them never did flower, although it had excellent leaf growth. Once the weather got warm enough I stuck all six of the plants out in the GH and have been watering them right along but apparently not paying much attention to them otherwise -- I have no idea how I didn't notice a flower stalk growing until now, but it's just about ready to open a flower! I'll add a photo once it does...
