Oprah Winfrey shows off jaw-dropping harvest from her garden

"Not one chemical used whatsoever!" she gushed.

Oprah Winfrey has quite the green thumb.

On Thursday, the talk show host showed off a an enormous cabbage she plucked from her garden, and her millions of Instagram followers couldn't believe their eyes.

The cabbage seemed to dwarf Winfrey, who told her followers: "It's heavy!"

"I'm telling you, not one chemical used whatsoever, because we don't believe in it around here," she said. "It's gonna make a lot of good slaw for Memorial Day!"

Winfrey, 66, recently took part in Facebook's virtual "#Graduation2020: Celebrate the class of 2020" ceremony, and even delivered a commencement speech to this year's graduates. In her call to action, she encouraged people to think deeply about what matters most to them and what essential services they can perform.

"My hope is that you will harness your education, your creativity and your valor, your voice, your vote, reflecting on all that you've witnessed and hungered for, all that you know to be true and use it to create more equity, more justice and more joy in the world," she said. "To be the class that commenced a new way forward, the class of 2020: Bravo, bravo, bravo, bravo."
