Banana Shrub

I just had to share the beautiful flower of my Banana Shrub or Michelia figo. I wish the Internet had smella-vision(when will someone invent that?) because the flowers smell deliciously like banana candy. Michelia is related to Magnolias and one can see the resemblance in the flowers. It's native to China, blooms only in Spring and will slowly grow 6-10 ft.

I've had this one for about 20 years since my nursery days. It's in a 7 gal can and not too happy. And I'm afraid to plant it in the ground because it has that horrible yellow oxalis with it that came up from the ground at our old house and would spread like crazy. Maybe it just needs some fertilizer and more care.
