When I first saw brussels sprouts at a farmer’s market I was flabbergasted. Who knew that these little cabbages grew along a large stick, looking for all the world like a medieval club?

What were these bizarre little veggies anyways? Why do I suddenly love them after hating them as a child? Okay, adding sautéed bacon and garlic may have something to do with it.

What’s in a name?

Why are they called brussels sprouts? Because it sounds better than Paris sprouts or Rome sprouts?

Brussels sprouts were first grown by the Romans. By 1586 the Belgians were growing them like crazy. They were sold in markets in Brussels, which gave them their name. Wouldn’t it be interesting if other vegetables were named like this?

How did they make it to Canada?

From Belgium the sprouts became popular in England and France. Apparently Thomas Jefferson was a fan, because he introduced them to the United States in 1812. I assume that from there they crept into Canada. They are also grown in Europe and Australia.

Today, most of the sprouts grown in Canada don’t come from Belgium, but are hybrids made in Japan or Holland. Sprouts need a cool climate and are allergic to heat, so Canada is a perfect place for them.

Which province in Canada produces the most Brussels sprouts? If you guessed BC, you’re right! Ontario and Quebec are close seconds. Every year, the sprouts harvest in Canada is worth over $7 million. Not bad for a bitter veggie people love to hate.

Apparently Canadians have a bigger taste for sprouts than Americans. When we don’t make enough locally we’ll import some from California. The advent of frozen food also increased demand for brussels sprouts. In Ontario the main variety grown is Jade E. Now doesn’t that sound exotic and exciting?


Speak softly and carry…brussels sprouts?

Instead of having one head like a lettuce, Brussels sprouts grow multiple heads along the stem. Just when you thought brussels sprouts couldn’t get less horrifying. The main stem is 2-3 feet long and the sprouts are leaf buds that develop along it. Brussels sprouts have mini stems inside, which you’ll see when you cut them in half. And, as I said, it looks like a knobby war club!

The sprouts grow from the bottom of the plant up. They are ready to pull off the stick in fall or early winter.

Full of goodies

What are these green balls good for? Well brussels sprouts have lots of fibre, vitamin A, C and K as well as manganese.

With sprouts, bigger is not better. Small is beautiful and tasty.

Apparently if you draw an X on them with a knife they will cook evenly. Hmm, I might have to try that.

Don’t cook them too long, or they’ll go grey and stinky. If you start smelling sulfur, stop cooking.

Cabbage Patch Kids

There’s a good reason that brussels sprouts look like little cabbages- they’re the same species! In fact, Cauliflower, broccoli, cabbage, kale, kohlrabi and brussels sprouts also belong to the species Brassica oleracea. Just like domestic dogs, these differently-shaped vegetables were created by humans through careful breeding of the wild cabbage.

Just like with dogs, different people bred the plant to do different things. Some wanted huge hunting dogs, others wanted tiny lap-dogs. brussels sprouts are the tiny lapdog.

The original wild cabbage was just a weedy little plant in the Mediterranean with nutritious leaves. Now it’s one of the world’s most important food crops. It looked and tasted a lot like kale and collard greens. Brussels sprouts were a late bloomer, and were the last kind of cabbage that ancient gardeners developed.

Brussels sprout sex

Believe it or not, brussels sprouts have flowers! We don’t think about them because we eat the leaves, but their flowers are yellow with four petals.

Just like different dog breeds, brussels sprouts and cabbage can mate with each other and have babies. I’m just not sure what those babies would look like.

Actually, we know what they’d look like. In 2010, the British company Tozer bred a hybrid of kale and Brussels sprouts. It looks like a stem of frilly spouts. They call it a flower sprout.

Cabbage may look like lettuce, but don’t be fooled! Lettuce is in the sunflower family, while cabbage is the mustard family.

What are you waiting for? Get out there and eat some brussels sprouts!

Maple Madness

By rights, Canada’s national symbol should be a pinecone.

Pines grow all across Canada. They resist cold, dry, wet and windy weather like true Canadians.

But we’re stuck with the maple leaf.

Here are some things you may not know about Canada’s national tree.

National Symbol?

The maple leaf wasn’t always on Canada’s flag. In fact, Canada didn’t have its own flag until 1965, 96 years after it became a country. Before that Canada used the British Union Jack or the Red Ensign.

As the centennial approached, there was more pressure for Canada to have its own flag. “The Flag Debate” was a heated time in Canadian history. The Liberals and New Democrats wanted maple leaves. The Conservative party liked the British history of the Red Ensign, but French Canadians understandably did not want a British flag.

A call for flag ideas went out, and 5,900 designs poured into Ottawa. It took parliament 37 days to agree on the one we know today.

As a Canadian symbol, the maple leaf dates back to 1700. It popped up in crests, badges, songs, and on the Canadian soldiers’ uniforms during the World Wars. From 1876 and 1901 it was on the back of every coin, not just the penny.

Not a Canadian Exclusive

Of the 150 maple tree species, China has 100 and Canada only has 10. We make up for it in syrup and maple leaf merchandise.

Most of Canada’s maples grow east of Manitoba. They say one species grows in every province, but that means the arctic territories are maple-less. Like I said, pine trees would be a better national symbol because they grow everywhere.

The maple tree wasn’t actually Canada’s official tree until 1996. Oops. There’s a “make like a tree and leaf” joke here somewhere.

What makes a maple a maple?

I’m glad you asked! All maples have winged fruit called keys or samaras. Samara is botany-speak for helicopter seeds. If you see double-bladed helicopter seeds, it’s probably a maple.

I see your true colours

The leaf on Canada’s flag is red, which means all maples turn red in the fall, right? Wrong! It depends on the species. Autumn colours can range from yellow, pink, and orange to deep red and purple. This makes fall in Southern Ontario a veritable rainbow.

You can’t even count on Red Maples to have red leaves-some varieties go yellow or orange. Leaf colour also depends on how hot the summer was, and how cold the fall is.

Killer leaves!

The leaves of the Red Maple can kill horses. Yes, that’s right, these pretty red leaves are toxic when they’re dry. If a horse eats too many their red blood cells start exploding. Not good. They die of lack of oxygen, which red blood cells carry. However, fresh leaves are completely safe for horses. Nature is weird.

How sweet it is

The Sugar Maple leaf is the one on the Canadian flag. As you may have guessed, this is the tree maple syrup comes from. Canada produces 85% of the world’s maple syrup, and most of it is exported.

Humans aren’t the only ones that steal this tree’s sap. Squirrels will eat off the spring buds to get a taste of sweet nectar. Birds and squirrels will also eat the seeds out of the samara. Luckily for them, Sugar Maples have a bumper-crop every 2-5 years.

Ideally, these seeds will turn into baby trees. Unfortunately, deer love to munch on the seedlings. Gulp, no more tree. Seedlings can survive this abuse, but grow into deformed trees. If they survive this long, they can live from 200-400 years.

Sugar Maples have flowers! They’re tiny little green things pollinated by bees. Most trees have both hermaphroditic and single sex flowers. Bizarre.

Prairie Perfect

Not all maple leaves look like the Canadian flag. The Manitoba Maple’s look really different. These trees are super successful because they grow in a lot of different soils. They like to hang out with their friends in forests, as well as in disturbed areas and along rivers. They are found in most Prairie Provinces. Their seeds are important winter food for birds and squirrels, and moose snack on the twigs.

Invasive maples

Norway Maples were imported to Canada in 1778 from Eurasia. They were a popular city tree because they resist pollution. After Dutch Elm flattened many urban elms, Norway maples became the favorite tree of urban developers. Now they’re everywhere. If you see a maple with large yellow or purple leaves, that’s a Norway Maple.

Unfortunately, this invasive tree jumped out of cities and started crowding-out and out-competing native maples. It’s very successful because it has a long growing season and makes 2000 seeds a year.

Also, we learned pretty quickly that they are awful city trees. Unlike Sugar Maples, Norway Maples only live around 60 years. At 35 the wood starts to weaken, and you end up with branches on your car after a snowstorm. Needless to say, it isn’t planted any more.

There you go, more than you wanted to know about Maple trees! Now get out there and try to find one.
