The first Amaryllis bloom of the season opened for me right before Christmas. It was the 'Lemon Lime' bulb I'd bought in November. Shortly after potting it up, it put out two flower stalks. Yesterday I cut the first one off because it was done blooming, just as the second one is preparing to open. 'Lemon Lime' is considered a dwarf amaryllis, typically growing to a height of 16-20 inches. Bloom size measures approximately 4-5 inches across.
'La Paz', a cybister amaryllis, is the only other one I've got potted up right now and it's just beginning to open. This bulb is one of the very first amaryllis I ever grew, having purchased it in the fall of 2005.
During the summer, my bulbs are put into the ground in full sun so they can beef up for blooming the following winter. I lift them in late September, before first frost, and they're then stored in the basement until I pot them up again.
