Answer: Royal Star is a variety of Magnolia stellata and blooms in very early spring before the leaves come out. It blooms at a young age, so even a new plant should have a nice display. Unfortunately, it blooms so early in the season that the buds and/or flowers can be hit by frost and ruined. This is true even though Royal Star blooms a bit later than most of the stellatas. I would suspect that is what happened to your flowers this year although it is also possible that if it is in a very windy or exposed location it is too cold for it; the plant is rated hardy into zone 4 but a sheltered microclimate out of the wind is always recommended, even in warmer zones than that. I hope this helps you trouble shoot.
