Opal is on the verge of a repolishing, following other jewel names like Ruby and Pearl. A Top 100 name during the first two decades of the twentieth century, the opalescent Opal has a good chance of coming back as another O-initial option.

Pema is related to the more familiar Hindu name Padma and means lotus flower. This delightful name was given to only 14 girls in the USA last year, so it's guaranteed to be a unique choice. Pema is probably most familiar to Westerners through Buddhist nun Pema Chodron and through Jetsun Pema, the Dalai Lama's sister.

There's a football player called Pepper (born Thomas and given the childhood nickname for sprinkling pepper on his cereal) Johnson -- but this sounds more like the name of a cheerleader.

Poppy, unlike most floral names which are sweet and feminine, has a lot of spunk. Long popular throughout the rest of the English-speaking world, Poppy is finally starting to rise toward the top in the US, where it entered the Top 1000 for the first time in 2016.
