Reflecting on last week’s post, it seems that weeds get a bad reputation. These native plants that grow liberally in our gardens are quite often deemed useless and a pain. However, small, non-threatening amounts of weeds can offer good services to … Continue reading
Recently I had the pleasure to listen to Katie Porter talk about her adventures in wild harvesting. Being self-sufficient and living off the land is a pipe dream of my own, and after the talk I feel a bit more comfortable trekking and munching in the wilds of Nova Scotia. Just make sure you’re well equipped with a good field guide before you go out, take my words with a grain of salt, and you’ll be good on your own in no time.
So lets start with a few safety tips: safety first after-all. As a rule, avoid mushrooms, yes some are edible and delicious, but some are dangerous and deadly. There is no way as a lay person that you can guarantee a certain fruiting fungoid is delicious over disastrous, so stay clear, and admire their beauty from the other side of a camera. Assume they’re all poisonous until proven otherwise, ok?
Forage from a safe area, make sure you’re away from the road and stay clear of areas that could be contaminated. That could be a field that was once a gas station, dry cleaners or roadsides. Stay clear of former mine sites, and mine slag fields. Some heavy metals can be left behind at these sites and taken up by plant’s root system into the leaves and stems.
Heavy metals are not good, except bismuth the active ingredient in Pepto Bismol. So, you’re safe now. Are you thinking of that perfect place to go pick wild blueberries, harvest your spring time fiddle heads, or munch on naturalized Japanese knot-weed? Good, now tell me where that is, or keep it a secret to enjoy on your own! Are you as shocked as I was that Japanese knot-weed is edible?
This bane of a killer weed was brought to Canada as a honey crop for bees. Their large white inflorescence provide delicious light coloured honey, and their unstoppable growing habits make them impossible to remove without small nuclear arms. But you can get your revenge on the hollow bamboo like plant. Young shoots under 12” are edible, and can have a sour lemony-rhubarb like flavour. They can be used in lieu of rhubarb or can be cooked like asparagus. Recipes from Katie Porter
Nippon Knotweed Salad
*Japanese Knotweed (Fallopia japonica, syn. Polygonum cuspidatum)
Serves 4. *google “itadori recipe” for more ideas
3 young shoots of Japanese knotweed, steamed for 3-5 minutes, chopped
1 teaspoon salt
1 Roma tomato, chopped finely
1 small red onion chopped finely
1/4 cup finely chopped parsley
3 tablespoons toasted sesame seed oil (sesame flavor compliments Japanese knotweed well)
2 teaspoons Japanese soy sauce, such as Kikkoman
juice of one-half lemon
pinch of freshly ground black pepper
1/8 teaspoon dried dill
Another invasive beast of an edible plant is garlic mustard.A relative of mustard, cabbage, and rapeseed, this mustard plant tastes of garlic. It apparently makes a good pesto.Those seed pods are the best way to tell if it’s in the mustard family, I think, but I’m just an armchair botanist, look it up to be sure. Make sure if you find this plant that you do not move it, uproot it, or replant it. It is an invasive species that violently colonizes Nova Scotia. It’s a pest in the Valley, and it may soon be a pest across the province. So eat it, or kill it, don’t move it.

Garlic Mustard (Alliaria petiolata) Pesto from http://www.maipc.org/morerecipes.html,
Submitted by Jennifer Chesworth, Centre Hall, Pennsylvania 16828
1/2 Cup Olive Oil 1 Cup Pine Nuts or Walnuts
1/2 Cup finely grated Parmesan Cheese Enough Garlic Mustard leaves to choke a horse (or to clear a forest floor) Finely mince the walnuts and garlic mustard. An electric coffee grinder works like a charm. Add Oil and Cheese, serve with pasta or rice or other whole grain. For vegan pesto use Nutritional Yeast instead of Cheese. Harvesting Garlic Mustard: take out the entire plant including the roots early in the season before it has a chance to flower. Young first leaves are best for pesto (and for salads or as a steamed green).
Use only the leaves for this recipe. Remove the roots from the area you are clearing as they will re-establish themselves if left in a pile on the ground. If you pull up garlic mustard after it has flowered beware as it will develop the seedhead even after it is pulled from the ground Ghetto Broccoli, very delicious.
Katie Porter is very excited and knowledgeable about fiddle heads. If you’re a good Maritimer you have your patch you visit as a family to gather these delicious spring vegetables. Sadly this is a tradition unknown to me until recently, even though I had a large stuffed version of this vegetable: It was the mascot of 1985 Canada Summer Games in Saint John, NB. The fiddle head is the baby ostrich fern, and have been vilified on-and-off as a possible carcinogen. To cut down on any risk, fiddle heads must be cleaned of their papery membrane, and must be cooked well before being eaten. Since I missed picking them this year, I got mine from the Halifax Seaport Farmers market, and cooked them up with some garlic and almond milk, over shrimp and pasta. I suppose you could also use some of that garlic mustard from before too!From vegetables to fruits. Did you know that rose hips are edible? They’re packed with the scurvy fighting power of vitamin C. So take those if you cannot get limes next time you’re sailing the seas. You can also find delicious wild strawberries, blackberries, cranberries, tea berries, raspberries, and huckleberries, among many more local fruit.
I recommend http://northernbushcraft.com/ as a good resource with great pictures. There are also apples across the province, abandoned orchards. In short, everywhere you look there are wild edibles, if you know how to look that is. Well that’s all for me.
I’m sorry for the two week delay from talk to blog, but I hope you enjoy. Written by Schuyler H Smith ( @skyhsmith )

Walking into the North branch library on a damp rainy day, the last thing I expected was to be staring at a bouquet of local flowers. Something about the haphazard bundle of twigs and flowers set the tone for David Patriquin’s talk on Native Plant Identification.
The topic could very well have been a very dry dissertation on Linnaean nomenclature and dichotomous differentiation to arrive at a Latin name. Dr. Patriquin made the speech lively with his animated voice, prizes of local plants and books, and constant participation with the audience.
Dr. David Patriquin introduces himself, not as an expert on native plants, but as an Oceanography student gone awry.
@skyhsmith: In 2004 dr. Patriquin decided to learn about his “biosphere” or 50km from his house to get to lawrence town and Polly’s Cove #nativeplant
He became interested in organic farming and gardening, and developed a love for what we call weeds. In fact, most of our food crops came from weeds that grew well in disturbed soils.
@skyhsmith: Most weeds are “friendly exotics” which are important for wildlife, pollinators, and organic management for farming #nativeplant
We started talking about introduced ‘exotics’ vs. native plant species. Most exotic plants are not much of a threat to our biodiversity. Plants like your garden impatients cannot survive without you, and cannot naturalize. Naturalized plants include clover and dandelion, which thrive in freshly disturbed soil. We freshly disturb soil, a lot, everywhere we go.
@skyhsmith : Nova Scotia has aprox. 2k wild plant species. 62% are native, pre European settlement. The rest are naturalized. #nativeplant
Dr. Patriquin shared some of his favourite resources for determining a plants identity, including the website for the Atlantic Canada Conservation Data Centre the best online source for identification. Since it is quite difficult to lug large books, this link may be the best way to have a way to identify plants on the go. Some books he suggests are Newcome’s Wildflower guide, and Carl London’s Native Orchids of NS.
Since Nova Scotia is an Isthmus, and it is relatively separated from the rest of the North American mainland there is very little biodiversity, though we have several biomes. These including Salt marshes, dunes, bogs, Acadian forest, boreal forest, and even some arctic areas in the Cape Breton highlands left over from the last glaciation.
Dr. Patriquin brings our attention to the flowers he brought. They are all from Point Pleasant Park, including, verbena, red maple, pin cherry, and honeysuckle, all gathered that morning.
@skyhsmith: There are about 300 types of plants at Point Pleasant Park. #nativeplant
He recommends that you do not take samples of plants from the wild. While there are few endangered species in HRM (such as ladyslipper) it is best to keep a digital herbarium: if you don’t need vegetation samples: take pictures.
@Skyhsmith: Hurricane Juan gave Point Pleasant Park a chance to biodiversify. Lots of goldenrods and asteracea in the first years #nativeplant
The deforestation from hurricane Juan allowed the park staff to bring it closer to the Acadian forest biome it would have been without our interference. For example, exotic linden trees are being replaced with local basswood trees. Most surprisingly, berries took off like weeds. How did they get there though? Dr. Patriquin suggests that some existed but were hidden by other plants, and that birds brought others.
We are becoming more aware of planting local, and it shows. With professionals like David Patriquin, we are moving forward. We cannot forget that naturalized exotics are now part of the equation, and are in some cases very necessary for the local fauna; including the red clover seeds the Ecology Action Centre gave us at the end of the evening.
Follow this link to an incredible resource that Dr. Patriquin put together.
