In June, 2010 I planted 100 fresh seeds with 97% sprouting. These are open-pollinated seedlings, the "baby-mama" being Slaughter Pink. My Plumeria is actually part of Elizabeth Thornton's collection that her adult children sold after she passed around 2007. Last year, I cut each leggy seedling in half & replanted the cutting into it's original pot because of lack of space for winter storage. They were over 3 feet tall. Not one of them has ever bloomed. I have about 40 other Plumerias, and the seedlings get the same care every year as the others. They get plenty of sun & I fertilize with Superbloom, they are in Miracle Grow Moisture-Control potting soil as some years (like this one) we get more rain than they need. The plants all appear to be healthy. But no blooms. What am I doing wrong?
