Magnolias bloom again in summer

A week or so ago, I noticed buds on a magnolia near the Science Center.  A few days later, there were blossoms.  The magnolias blossomed in spring, then lost their flowers, so I thought they were done for the year.

Today after work I went over to observe and photograph the magnolia trees between my office and the Science Center.  Each of the three trees has at least one flower.  The flowers tend to be on the southern sides of the trees.  The tree with the most southern exposure has the most flowers.There are just a few flowers, but there are quite a few buds.
