I live in Hawaii where we get around 60" annual rain. Temperatures vary from 55° to 80°F. While I do have some Dutch white clover growing here and there on my farm, it is not thriving. I seeded it years ago and tended it closely, getting quite good germination. But most of it died out within the first year. What survived stays rather small, not sending out long runners. The runners are short. The flowering is spotty.
Years ago I use to live in New Jersey where the winter temperatures routinely were in the 20's°F at night and usually below freezing or slightly above during the day, and it was not usual for winter nights of 0°F from time to time. Summer highs were always on the 90's. Hot and humid. But the clover thrived there. It grew aggressively. It spread. It heavily bloomed each year. The soil was sandy there, which may be a contributing difference.
I don't know why it doesn't do well on my farm. I've never investigated to find
the answer.
