In 2014 I made a cross between these two yellow Komoriya hybrids:
Moonshine is on the left and Piyo Piyo is on the right. I originally had quite a few seedlings from this cross, but have lost many of them to rot. I was a little worried that I might lose them all before getting any blooms. But this week I was fortunate to spot a scape of a survivor in one of my hippeastrum beds.
The coolest thing about this cross is that the flowers are held vertically like a Zephyranthes, so I am dubbing this cross 'rainlily'. In fact, I first thought I might have accidentally made the cross with pollinon from Zephyranthes atamasco, which was blooming at about the same time as the photo above.
Here is a photo from above. At first the flowers were yellowish with a pale blush undertone:
The color intensified with age. This bed gets a few hours of direct, hot sun each day, so this undoubtedly contributed to the color.
