It's a nice collection and getting 25% to flower in the first year is a great result.
I doubt much will flower over winter, there are autumn bloomers but they would be producing a spike already now.
Do you have a P. mannii? - that is a true winter bloomer.
Then the season starts with the sedirea japonica and the rest follow.
I have some Bear Queens from schwerter I got just before Brexit that are two years old. One did make a small flower but nothing more since. I am also very hopeful next summer will be their time to shine but it will be like 3 years from when I bought them.
If you can do better than that then you would be doing something better or got a better phal than me
