It’s the versus episode they said couldn’t be done.
Well, okay, not sure who “they” are, but something has certainly been conspiring against it. We first attempted an episode on sunchokes, also known as Jerusalem artichokes, in the fall of 2024, before Plants Always Win was launched. It got left on the cutting room floor. Then in September of this year we recorded a proper Sunchokes vs. Sunflowers face-off, spending two hours in the recording studio.
We later found out that Sean’s audio had quit after six minutes.
But if you’re reading these words, we have finally succeeded! With the last of the warm autumn sunshine, we are bringing you sunflowers vs. sunchokes. Or, to put it another way, annual sunflowers vs. one of their many perennial sunflower cousins. Both are native to North America, and both are prolific food crops. The first, though, has been bred for its seed while the second is used for its tubers. And only one of them was at the centre of a $25 million scam that threw parts of the United States and Canada into an uproar in the 1980s.
Find out which one that is one by listening…and then reach out by email or social media to tell us which sunflower YOU feel won this week’s plant face-off.
