I have never had my own before, but I would wholeheartedly recommend buying an amaryllis bulb when they are for sale around Christmas time. What a marvel to watch sprout, grow, and then bloom (yes, I know I sound like a real nerd). This is a two day period in the life of my amaryllis. Yesterday it was just about ready to open, this morning it was almost there, and then this afternoon it is wide open in all it's glory.
Earlier on today, slowly opening in the morning sun (above).
