Flowers are fragrant, consisting of 9-12 strap shaped petals (tepals) about 2-3" long and 1/2" wide, wider at the tips. This image is the cultivar 'Rosea'. Opening before the foliage appears.
Fruit is an aggregation of small follicles each releasing a seed with an orangish red seed.
Here are a few more shots of them in landscapes.
Other cultivars exist. 'Royal Star' has double white flowers. 'Centennial' has an upright narrow habit.
There is some confusion about the name of this species. It is often considered a botanical variety of M. kobus but the current thought is they are distinct species. Which makes it easier to understand how we might have M. x loebneri which is considered a hybrid between M. kobus and stellata.
Misidentification: Hard to say, unless you run into some of the cultivars of M. x loebneri which you might which have flowers slightly larger as well larger leaves.
