Onions, Perennial vegetables

Meanwhile in the Onion Garden Chicago

Leave a comment

I don’t often post here about my other two gardens, the community garden at Væres Venner and the Onion Garden Chicago at the Ringve Botanical Garden in Trondheim. 
The onion garden is nicely maturing and will be officially opened this summer on 26th August, 6 years since I started work creating a garden to house a national collection of old Norwegian perennial vegetable onions collected throughout the country, some 100 botanical species from around the world and many cultivars too!
Here’s a couple of videos showing the garden on 25th June 2023 close to peak flowering, although there will be flowering Alliums all the way from May to the first heavy frosts in October / November!
Tasty, beautiful and a great place to study pollinators! Can you smell it?
There are now over 500 pictures from the garden in this large Facebook album

Hablitzia, Laportea and Nettle Gnocchi

Leave a comment

What to do with the very last Sarpo Mira potatoes from the cellar? Last night’s dinner was Gnocchi made with Hablitzia leaf, Laportea canadensis (Canadian wood nettle tops) and stinging nettle tops. I must admit that our first attempt turned into a gnocchi soup, so we had a starter with exactly the same ingredients as the main course :) The second attempt was excellent though!

Edientomental, Perennial vegetables, Root crops

Rampions for the hungry gap

2 Comments

The rampions (vadderot in Norwegian, Phyteuma in Latin) has been naturalizing in my garden but so far keeping to the cultivated beds. I needed to dig up a few this week as it was outcompeting some other plants I wanted to keep. I cooked the roots and they were delicious and almost fibre-free and used in a salad. Along with other plants in the Campanulaceae this is a very useful root crop for the root hungry gap! And just look at the bumble bees swarming over the flower tops, always the most popular plant for the white-tailed bumblebees (jordhumler), one of the most useful plants to grow, both tasty (I use also spring leaves and flower buds), nice to look at and a pollinator friendly, ticking all 3 boxes required to categorise it as an edi-ento-mental!

Art, Perennial vegetables

Artist in Residence Elin Eriksen

Leave a comment
We’ve had a lovely 3 day visit this last weekend from artist Elin Eriksen from Nesodden starting a project based on my perennial vegetables. She sketched and photographed candidate plants in all 3 of my gardens, The Edible Garden, Ringve Botanical Gardens Onion Garden and the World Garden at Væres Venner! We look forward to seeing the results!
Elin has earlier created a poster of birds for Birdlife Norway (also for kids) and recently lead a course in botanical drawing for Sopp og Nyttevekstforbund at Valdres.

Turkish brockets

Leave a comment

This week, the tastiest part of turkish rocket / russekål (Bunias orientalis), the broccolis (affectionately known as brockets here!), were ready to harvest! Although considered an unwanted invasive nowadays in Norway, my 30 year old plant has never produced a seed. However, the plant died (I thought) a couple of years ago only for a number of new plants to appear from the roots some distance away. I hadn’t realised it did this. I was also puzzled to read on the Norwegian invasive species database that it is biennial and spreads aggressively by seed (see https://artsdatabanken.no/Fab2018/N/602).
Anyway, it made a delicious lunch stir-fried with St. George’s mushroom (vårfagerhatt), some leftover cooked potatoes and mixed into scrambled egg with chili and garlic. Read more in my book Around the World in 80 plants.

Mountain cultivation of Udo in Nagano

Leave a comment

On 9th April 2016 I was staying with my new friend Tei Kobayashi in the mountains in a lovely village, Nogura, above Ueda in Nagano Prefecture. I was put in touch with Tei through a mutual friend in Norwegian Seed Savers (KVANN), Caroline Ho-Bich-Tuyen Dang, when I put out a call for an interpreter when visiting the farm with the underground udo forcing caverns in Tokyo: https://www.edimentals.com/blog/?p=8284 and https://www.edimentals.com/blog/?p=7499
Tei had kindly agreed to travel down to help out!
She took me to see udo (Aralia cordata) being grown on a small farm in her village with a villager who had knowledge of sansai. The new shoots were just appearing through a thick layer of rice husks. Here’s a video and some pictures of this beautiful place! Thanks again to you Tei for your hospitality without which this would never have been possible!
There will hopefully be more posts from the visit with Tei as soon as time allows!
Tei starts talking about another use of rice husks, in nukazuke, fermented vegetables in rice bran (nuka), see https://en.wikipedia.org/wiki/Nukazuke
(Thanks to Tei for the following clarification: I just wanted to comment on the Udo cultivation process. I just learned that it is not “nuka “ but “momigara” that the plants are grown in to keep them white. “Momigara is the outermost husk of the rice kernel. “Nuka” is the inner rice hull it is very finely ground into an almost powdery substance. Nuka is the outer covering of the rice that is removed to make it white…it is often polished after the hull is removed”.)

Fact-finding mission: promoting perennial vegetables

Leave a comment
 

On Tuesday 23rd May I spent a great few hours together with Eva Johansson and Annevi Sjöberg from Sweden in my 3 gardens. They were on a fact-finding mission in connection with the project  ”Främja fleråriga grönsaker i svensk matförsörjning” (Promoting perennial vegetables in the Swedish food supply).
The project Främja fleråriga grönsaker i svensk matförsörjning is financed  with funds from the Swedish Agency for Agriculture (Jordbruksverket) within the framework of the Swedish food strategy (den svenska livsmedelsstrategin). The project runs until Dec 2023. The Skillebyholm Foundation manages the project.
Jen from Nottingham in the UK was visiting this week to help and learn, thanks to an RHS bursary! She joined us on the trip and can also be seen in the pictures below!

Jen, Eva and Annevi were on an Allium-high after spending time in the Onion Garden Chicago at the Ringve Botanical Garden in Trondheim :)

God Save the King’s Hostas!

Leave a comment
My only post on last weekend’s big news item. This memory came up on my feed this morning. In October 2015 I talked about my book Around the World in 80 plants at the Walled Kitchen Garden Network Forum weekend at the National Trust Property Croome Court in Worcestershire, England. As usual I joked about Prince Charles having the most productive Forest Garden in the UK as he had a national collection of large-leaved Hostas in woodland at Highgrove. Little did I know that the Prince’s head gardener was sat near the front. After the talk, he introduced himself, astonished that Hosta were edible. I thought quickly and presented him with a copy of the book and signed it “To HRH Prince Charles, Good luck with your Hosta eating!”. I had known of the Prince’s good works within the organic gardening movement since the 70s and indeed Highgrove is managed as an organic farm.
I was surprised to receive this letter later that winter and it resulted in a correspondence about Hosta cuisine which lead to me being invited to Highgrove to talk more and see the Hosta collection (sadly, there are no pictures of that day as cameras are strictly forbidden nor was I allowed to see the pictures the staff took). I had a hope that the Prince might turn up, but he had a lame excuse that it was his Mum’s birthday…..and now I’ve had to modify the slide about Hostas and Highgrove (see the comments).
God Save the King’s Hostas!
