Based on my experience Rhodys do not grow well in sunny places.
I'd plant something else.

i don't know any that stay shorter than a meter, either.
i think what the OP might want is azaleas? they love sun & some stay
really small (i have one that's over 10 years old & about a foot
high. it gets wider, but not taller)
