However some hydrangeas were blooming withand had pink, purple, or blue flowers.

I think this is what you were trying to say, but feel free to comment if it wasn't and I'll try to rephrase it.

I appreciate that Japan has four different seasons, because I can realiznotice and enjoy the seasonal changingchanges in the seasons.
