Yep, that's a Star Magnolia shrub. They have blooms only in spring and then leaf out. I have one that hasn't found it's happy place to live and one that is taller than I am. They are both the same age. I think I should likely trim it down but oh, I love looking at those beautiful blooms in spring.
Green thumbs are developed. Read, try it, and enjoy it! lol lol
