The voluptuous and fecund Himalayan blackberry was introduced to America by the eccentric plant breeder Luther Burbank in 1885. Burbank had some good ideas — like elephant garlic and the freestone peach — and a few that may have seemed like good ideas at the time, but which turned out to be big mistakes, such as eugenics and the Himalayan blackberry.
Burbank originally received the seeds from a collector in India, hence the name. However, the Himalayan blackberry is native to Armenia, as is my grandmother who was also tough and prickly but incredibly sweet, if you could get past the thorns.
The Himalayan blackberry is the unsightly and ubiquitous default hedgerow on Vashon. It erodes soils, invades creeks and crowds out animal habitat. Invasive blackberry overwhelms native plants, including salmonberry, thimbleberry and trailing blackberry, which fruit earlier in the season and feed birds at a critical time.
These blackberries are invasive in part because they’re delicious. They’re also high in vitamin C, beta carotene, minerals and phytochemicals. Most plants that end up as invasive species were initially propagated by humans because they were valuable to us in some way. Writer Michael Pollan argues that plants evolved to gratify human desires so that we’d help them multiply. The blackberry offered us sweetness and sustenance, and we invited it into our gardens. It betrayed us and repays our cultivation with a blood-thirsty attack on our open spaces.
Himalayan blackberry is hard to kill, which has caused many individuals and communities to just give up trying to control it. Seattle plant expert Arthur Lee Jacobson urges perseverance and courage: “Pray for ruthless single-minded focus. Arm yourself with tough leather gloves and weapons of choice. Go to it, hacking and uprooting like a demon.” Hand-to-vine combat is important for eradicating blackberry vines, but maybe declaring war on them isn’t the only answer. In the Caribbean, locals are battling the invasive lion fish by eating as many as they can. They conduct lionfish derbies, publish cookbooks and share tips for handling its venomous spines.
Turns out lionfish are delicious — just like blackberry. In that spirit, why not have blackberry picking and eating contests, compile our pie and cobbler recipes and share tips for the best berry-picking combat gear? How about monetizing this monster vine by making blackberry brandy and wine? Vashon grows way more blackberries than strawberries these days, so perhaps we could change the Vashon Strawberry Festival to Himalayan Blackberry Days to reflect our current reality. Since goats love eating blackberry plants, we could host Goat Trials, like the Sheepdog Trials, where skilled goatherds guide their trained competitors through blackberry-ridden obstacle courses.
In 1729, Jonathan Swift anonymously published “A Modest Proposal,” a satirical essay suggesting starving Irish peasants could sell their children to the British upper classes for food.
Swift wrote, ”A young healthy child well nursed, is, at a year old, a most delicious nourishing and wholesome food, whether stewed, roasted, baked, or boiled; and I make no doubt that it will equally serve in a fricassee, or a ragout.” This outrageous essay shocked the public, but it brought attention to a problem no one wanted to deal with. Eliminating Himalayan blackberry may seem as unrealistic as eliminating poverty, but that doesn’t mean we shouldn’t keep looking for creative solutions.
