This is progress so far today. There are 420 sts on my needles and I'm on round 64 of my modified pattern (round 70 of the original pattern).
My modified pattern has 12 petals and there are 12 repeats on each round. I have changed the plain knit round from 4 to 3 plain knit rounds and the hips that I had on my first Hemlock are not there.
I pulled in to exclude 2 of the petal formations with my hands, thinking that maybe I could have just done 10 but the hips came out. I do think 12 is the solution but will know for sure as I move on.
