White Plumeria, Frangipani. These little trees have the most awesome fragrant flowers. In Hawaii, they just grow and grow. You poke a branch into the ground and before you know it, you have flowers. In San Diego, you have to find a warm, sunny spot but they will grow outdoors here. I've had a lot of trouble getting the white ones to bloom; at least, until I chatted with a co-customer at a local nursery. Actually, I was talking to his wife in line at the checkout and lamented that my plumeria just wouldn't bloom. "Well," she said, "you must talk to my husband!" To make a long story short, he said the secret was to put lots of bloom fertilizer on them. I went back in and bought a jug of slow release bloom fertilizer and, well, you can see the results. So, it pays to be nice to strangers (at least strangers in garden shops!).
