A Dallas Arboretum horticulturist will be featured Saturday on the CBS series “Mission Unstoppable,” which spotlights female scientists to inspire girls to pursue STEM careers.

Jenny Wegley oversees more than 4.2 million plants at the Arboretum.

“I was really little when I started playing in the yard,” Wegley says in the segment. “It was always my safe place. It was always a place I could go and play in the soil.”

In “Mission Unstoppable,” Wegley shows viewers how she studies plants from seed to flower and uses a trial garden to collect data on each species to ensure they thrive in the Texas summer heat and are compatible within the 66-acre gardens.

Miranda Cosgrove, who starred in “Despicable Me” and the Nickelodeon show “iCarly,” hosts and produces the show alongside Academy Award-winner Geena Davis. It airs at 10 a.m. Saturdays as part of CBS’s educational programming block.
