A few may but more will look like PEOY. But given this is a complex hybrid a few will have very long petals closer to a sanderianum while others will have petals like a roth and then you will get everything in between. There will be no single outcome in this cross as you would get in a primary hybrid. The most common outcome will probably be something resembling a PEOY but it really is a bit of a lucky dip. You need to flower a dozen of these to ensure you get what you want. Good luck. I look forward to seeing yours in flower.
