This is Yellow Tiger "Ruth Luethans" AM/AOS x Michael Koopowitz "Alberta" AM/AOS. It is the first bloom for this plant, which was purchased as a seedling 6 years ago from Windy Hill Gardens. The plant has 3 healthy, blemish free growths, which I take as a sign of good disease resistance. Petals are 22cm on oldest flower. The flowers are not quite as dull as they are in the photo, but it is a gloomy day in the greenhouse, as it has been much of this winter. Mike
