We have plenty of magnolia trees in our neighborhood, now starting to pass their peak. I think of them as white or pink, sometimes mixed in lush groves. A few of them in our botanical garden are yellow, something I have not seen elsewhere. The centers of the flowers are fascinating. I haven't needed to tell a pistil from a stamen since 10th grade biology class but something interesting is going in here. Maybe one of our more botanically inclined friends can explain the structure.
