Batman, biodiversity and food

I love when my gardening activities attract wildlife and contributes to the biodiversity of this wonderful place!
I’m once again growing wapato (Sagittaria latifolia) in addition to Chinese arrowhead (probably Sagittaria trifolia) in large containers (sorry for the plastic!). I can see these containers from my sitting place in the garden behind the Amelanchier hedge and in the heat wave and drought we’ve been experiencing with record high May temperatures (over 30C not far from here), I’ve seen several bird species drinking. Today, I found a batman hoverfly (dødningehodeblomsterflue; M⁠yathropa florea) in one of the buckets:

Daniil and the duck potatoes

We like to give our helpers /wwoofers an experience to remember.
Daniil Titov is with us for two weeks and in between the sleet showers we harvested the wapato/duck potato (Sagittaria latifolia), originally from the Mississippi River :)

Rhizo-bacalhau

We occasionally eat wild fish and bacalhau is a favourite made from Norwegian dried cod that can be found in supermarkets here. More or less anything goes in bacalhau (bacalao) and although most people make it in the same way – layers of potato, fish, tomato and onions, often with chili – the Portuguese have hundreds of ways of preparing baccalao (dried cod). Being self-sufficient, detailed recipes aren¨’t useful and we use whatever is available at the moment. Winter is the time for stored bulbs, corms, tubers, rhizomes, and taproots. See below the picture for yesterday’s baccalao ingredients with 14 home grown below surface storage organs plus some greens (I’m pretty sure nobody else had this version of the dish…ever!):

Oca (Oxalis tuberosa): yellow and red varieties
Garlic / hvitløk (Allium sativum)
Wapato (Sagittaria latifolia)
Potato / potet (Solanum tuberosum) – 2 varieties
Jerusalem artichokes / jordskokk (Helianthus tuberosus)
Parsnip / pastinakk (Pastinaca sativa)
Scorzonera / scorsonerrot (Scorzonera hispanica)
Common onion / kepaløk (Allium cepa)
Cacomitl (Tigridia pavonia)
Yacon (Polymnia sonchifolia)
Burdock / storborre (Arctium lappa)
Madeira vine (Anredera cordifolia)
Parsnip / pastinakk (Pastinaca sativa) shoots – had started shooting in the cellar
Leaf beets / bladbete (Beta vulgaris var. flavescens)  – 3 varieties
Allium nutans (forced in the living room)
plus (not home grown) organic tomatoes, olive oil and olives
(I forgot the dandelion…will add tonight: we make enough that it lasts for several days….and the taste improves!)




Sam Thayer and Mississippi wapato

As I mentioned in my post about harvesting wapato in my garden a couple of days ago, I attended the Midwest Wild Harvest Festival in Wisconsin in September 2019 to do the keynote and a couple of talks and was lucky enough to be able to attend Sam Thayer’s Wetland Plant Hike along the Mississippi during which the highlight was the demonstration of wapato harvest. There had been record flooding that spring on the Mississipi and water levels were still high which meant that the places where Sam normally harvested were too deep. However, he did find a small patch to demonstrate harvesting techniques. As Sam mentions, this is how Canada geese do it! Did I mention that I rate Sam’s 3 books above all other books on wild edibles! His book The Forager’s Harvest has 16 pages on wapato! See the videos and pictures below:

Freezing Wapato and Chinese Arrowhead harvest

When I attended the Midwest Wild Harvest Festival in Wisconsin in September 2019, I was lucky to be able to attend Sam Thayer’s Wetland Plant Hike along the Mississippi during which the highlight was the demonstration of wapato harvest. Look out for the video I took that day in a post in the next few days. Earlier this week found me harvesting my own wapato, grown in large tubs in the garden….an altogether more invigorating experience, the gardener’s equivalent to winter fjord bathing, as the water temperature was only about 1C (and the following day the water was frozen); I had planned to try locating the tubers by feet the next day, but (fortunately) the thick ice made that difficult (OK, I’m a wimp as I could have broken through the ice with a pick axe ;))
I’m growing both North American wapato (Sagittaria latifolia; picture) and Chinese arrowhead tubers (Sagittaria trifolia) which were originally shop bought.
