Growing up in Seattle I spent summer evenings like this picking blackberries.
These days I spend more time trying to fend off blackberry vines in my garden.
If you’ve tried to do that, you’ve probably found that following one long blackberry vine to the source leads to another heading a different direction.
Kind of like the story I’m about to tell you, the answer to a Local Wonder question: “Where did our Himalayan blackberries originate?”
It was the end of the 19th century, and American life was changing dramatically.
People were moving from rural areas to towns and cities – including Seattle. Industrialization was creating a new middle class.
Down the coast in Santa Rosa, California, an eccentric guy named Luther Burbank was hard at work on his experimental farm.
Burbank didn’t have any formal training, but he was working feverishly to breed strange and wonderful new kinds of plants.
“He realizes the growing middle class is going to want to have fresh fruits and vegetables,” said Phillip Thurtle, who teaches in the University of Washington’s Comparative History of Ideas program.
“They’re not going to want to eat canned beans. They’re going to want to eat fresh beans all the time. But in order to do that, they’re going to have to be able to be shipped.”
Local Wonder: Is Seattle Freeze a real thing?
Thurtle said Burbank set out to create new varieties of fruits and vegetables that would be delicious and prolific – and that could withstand the voyage on the nation’s new transcontinental railroad.
Burbank sold his hundreds of plant creations through catalogs with pictures of shiny fruit and shinier superlatives.
He created the earliest of all large cherries, which he named the “Burbank.” Burbank’s inventions could also be weird – like a spineless cactus.
Or his potato-tomato hybrid, which somehow never took off. But others were smash hits. Like the freestone peach and elephant garlic.
“My favorite example is the Shasta daisy, because this is something that most of us have in our gardens,” Thurtle said.
Local Wonder: Where do Seattle-area crows go at night?
If you’ve had fries at McDonald’s, you’ve likely eaten a relative of a Burbank creation. A potato Burbank invented in the 1870s, called the Burbank, later mutated into a potato called the Russet Burbank. It's the most widely-grown potato in America today.
Thurtle said that Burbank was also working on another large-scale project – the thornless blackberry.
“Kind of the parallel to his spineless cactus or his stoneless plum,” he said. “He wanted to take the rough spots out of nature. To domesticate it for middle-class lives.”
Burbank traded seeds with fellow collectors all around the world. In a package from India, he found seeds for a huge blackberry with an even bigger flavor.
Burbank named it the Himalaya Giant (even though it’s actually believed to be from Armenia).
Burbank found that the Himalaya Giant grew like nobody’s business – but only in temperate areas, like the Pacific Coast.
In 1894, he offered the berry in a special circular he sent buyers in mild climates. It was popular.
By the early 1900s, the Himalaya Giant – which would eventually be known as the Himalayan blackberry – was especially thriving in the Puget Sound region.
Thurtle said Burbank’s business was thriving, too. Everyone wanted to see his plant laboratory. He was hanging out with Thomas Edison (light bulb) and Henry Ford (Model T).
Burbank had become an international celebrity. He was so successful at breeding plants that he became interested in applying the same principles – to people.
He started selling a new book that he’d written in his catalogs, “The Training of the Human Plant.”
Local Wonder: What’s the right way to go around Green Lake?
Burbank wrote that the crossing, elimination and refining of human strains would result in “an ultimate product that should be the finest race ever known.”
He considered the U.S. the perfect place to practice eugenics, because, at the turn of the century, there were immigrants coming from all over the world.
“Look at the material on which to draw,” Burbank wrote. “Here is the North, powerful, virile, aggressive, blended with the luxurious, ease-loving, more impetuous South.
“The union of great native mental strength, developed or undeveloped, with bodily vigor, but with inferior mind.”
Burbank’s theory of genetics was that an organism’s surroundings left an imprint that was passed on to future generations.
For that reason, he wrote that children should spend most of their time outdoors, communing with nature. Perhaps that’s why a Mercer Island boarding school for troubled boys was named after him in 1931.
Seattle boys running amok were sent to The Luther Burbank School on the shores of Lake Washington, where they learned to farm.
Today, only the dormitory remains in what is now Luther Burbank Park. And the only thing running amok are the Himalayan blackberries that escaped those turn-of-the-century berry farms and gardens.
Sasha Shaw, noxious weed expert with King County: “I mean, there is not a part of western Washington that is not touched by this plant.”
Shaw said the Himalayan blackberry erodes soil and crowds out native plants and animals.
“It can grow in dry soils, wet soils," Shaw said. "It grows into the forest, it grows in full sun. There’s really not a place it can’t succeed.”
Birds and other animals spread the seeds far and wide. Those seeds can live in the ground for years waiting to germinate. And once the plant is growing, when the tip of a vine touches the ground – it can create a new plant.
“People keep trying to kill it, and it keeps coming back,” Shaw said. “It really has everything going for it in terms of an invasive plant.”
Luther Burbank never got around to breeding humans. But it appears that he may have introduced a master race … of blackberries.
Correction 12:56 p.m., 8/25/2016: An earlier version of this story said that Luther Burbank created the Russet Burbank potato. He created the Burbank potato, from which developed the Russet Burbank.
