FORT WAYNE, Ind. (AP) — When Ukrainian immigrant Alex Babich stands in his Indiana backyard craning his neck to look 35 feet (11 meters) into the sky, he isn’t just staring at a sunflower. He is looking at his roots — and his future legacy.

The flower, nicknamed “Clover” and confirmed Wednesday by Guinness World Records as the tallest sunflower ever measured, stretches as high as a telephone pole.

Achieving the feat holds special significance for the 47-year-old Babich since sunflowers are the national flower of Ukraine.

Born and raised in Ukraine, he immigrated to the U.S. at age 14 in 1991 after the Chernobyl nuclear disaster. Seven years ago, he started growing sunflowers as a symbol of his love for his home country. Babich’s first sunflower was 13 feet (4 meters) tall, then 15 (4.5), then 19 (5.8). Quickly, he began asking himself, “How far can we take this?” Babich said the record-breaking flower was the result of “trial and error over years.”

“It’s one of my kids,” he said. “You’re out there every day taking care of it.”

Babich’s 10-year-old son also had an important contribution that earned the towering flower its name. He would climb onto the scaffolding and place four-leaf clovers on the sunflower’s leaves, for good luck.

“I’m going to die someday, but the stories of this flower will live on,” he said. “My kids will be telling this story to the grandkids.”

When measuring day came on Sept. 3, Babich was nervous.

About 85 people had gathered to watch, including several master gardeners from a local university and representatives from the Allen County Department of Weights and Measures.
