Based on your post last year Xavier I picked up the last 3 plants he had listed on his website of this cross. He could have more but not listed on his site
One of 3 I picked up from Ten Shin. I took a chance on a F2 cross of PEOY. I also picked up aF2 Lady Isobel which hasn't bloomed yet.
I think this plant has great potential with maturity.
Very nice start. Yes, lowii leans hard and it's best to go with it. You will fight a loosing battle trying to stake upright. If there is a candidate for hanging basket culture, lowii would be it.
Second blooming, Sam bloomed it first. The longest petals are 60cm. Sam told me on the first blooming five flowers in the 65cm range. So there is potential to be better. I'm planning on breeding with it.
PEOY x philippinense, bought this plant in 2011 and received an AM in 2014. Named after my oldest daughter. I think this is the first time for 5 flowers.
I would question the ID as well. To me it looks like a cross I also picked up from Sam which I have not bloomed but your flowers are what I'm expecting.
Sweet Kolosand. As for staking I like to see the long petaled slippers with an arch to the spike displaying all the individual petals hanging in rows. Just a personal preference
