This is Brunswick Glen, registered in 1999 by Carter and Holmes.
Keith Davis talks about this cross:
Blc. Brunswick Gem 'Coral' AM/AOC
"This was a cross made by Gene Crocker at Carter and Holmes, the parents used were Blc. Owen Holmes 'Mendenhall' x C. Horace 'Maxima'. Gene took a trip to Australian in 1994 and Gordon Vallance got a flask from him. Later, Gordon asked C&H if he could name the cross and was granted permission. He gave this particular clone his wife's name, 'Coral', which to me, also describes the color. I heard that at least one of the cross came out yellow. My Australian Friend, Zelda, procured a division for me, thus completing the world tour. I found out recently that Cal-Orchid had some for sale that came indirectly from Australia."
