Why this glorious gardenia may be flourishing in the summer sun

Based on my personal experience, I have concluded that a jolly dentist is about as rare as a floriferous gardenia. So it is only fitting that Dr. Cerniglia, the jolliest dentist I know, has a gardenia blooming at full capacity in front of his Reseda office.

Gardenias are recommended for full to partial sun, and this specimen faces south, getting direct sun virtually all day long. Yet, like many plants recommended for full sun, including roses, I have found that gardenias may suffer in such an exposure when summer temperatures soar.
