Picotee - what a nice word! I just love to say it ;-)
My favorite Amaryllis is Hippeastrum Picotee, a white flower with red edging
wikipedia says, Picotee is a variety of flower whose edge is a different color than the flower's base color. The word originates from the French picoté, meaning 'marked with points'.
As with most of my Amaryllis collection, I keep this one potted.
An earlier blog entry shows more of my Hippeastrum and I tell a little on how I keep mine: clickie
