Blc. Ports of Paradise greens are pretty hard to beat! This clone, registered by Stewarts Orchids in 1970, was purchased from Bill Maxwell in 1983, while he still lived in Fresno CA...before moving to his marvelous mountainside on Maui!
I find both 'Lemon Ruffles' and an unawarded clone, 'Big Sir Green', bloom better more consistently for me than 'Emerald Isle'. Look at the difference in that greenhouse wall after its fall scrubbing!
