Plumeria growth

My first post on plant. My wife thinks I have a green thumb- I either keep plants and they will prosper or I can revive near death or what appears to be dead plants back to life. I wouldnt say its a gift, but I think everyone can have the green thumb if you pay attention to you teacher duirng high school biology, do research and learn from others' failure.

Plumeria is not a plant you can grow outside yearound in Wisconsin. I managed to keep it alive (with leaves) through the winter indoors, and then placed it outside when spring hits wisconsin in May. That's right, spring did not arrive until may thus year.

You can tell the growth rate difference, pale green on the stem is from last September through this april. And the dark green from the tip two inches down were all in the last three months!
