Helen, my Brs. is Datacasa 'Coos Bay' x Edvah Loo-logissima 'Valentino'. I call it Tango. The flowers are more of a yellow than a chartreuse with chocolate/marroonish markings. I'm not sure of the age. I've had it 6 weeks and it had 1 spike in bloom then. It has 6 or 7 pseudobulbs. I know you are excited about yours. Congrats, Lisa
