This orange amaryllis was identified as Nagano on GardenWeb's Amaryllis Forum. Cruising thru Penning's Site it does not resemble it at all.
This is a beautiful orange amaryllis. The netting on the petals are pretty. It is hard to capture its real color and it is downfacing while it is half open. The flower measures about 7" in diameter.
Below, it is pictured with Apple Blossom. The netting on both of them is quite visible.
