Hablitzia under Norway Spruce

1 Comment

Hablitzia tamnoides (Caucasian spinach / stjernemelde) has self-sowed numerous times in my garden but only up to now on cultivated beds with naked soil.  Now for the first time I noticed one had popped up in dry soil under my two oldest Norway spruce trees (Picea abies; gran) which are probably in their 80s. There are a number of Hablitzia plants in a bed about 8m above this site  (I believe that  the shiny seeds of Hablitzia can disperse by falling on icy snow and are blown by the wind). This is an area which had been invaded by hedge mustard / løkurt (Alliaria petiolata). I’ve been systematically removing this plant from this area and other parts of the garden where it was rapidly taking over. Incidentally, another climber, Bryonia alba, appeared in the same location in 2010, but died after a few years (last picture). It wil be interesting to see if this plant manages to establish here. 
No, I don’t think Hablitzia has the potential to be invasive!

Walking’s not healthy for Habbies

Leave a comment

I’ve been growing Hablitzia tamnoides, affectionately known as Habbies, for over 20 years and this is the first registered mortality. On a shallow bed under a birch tree, plants lift during winter as if to walk off to take over the world (OK, probably just frost heave as also happens with parsnip roots), and one of them is now no more, a dead Norwegian habby :( 

Here’s a few more that are going the same way of I don’t rescue them:

…and below is a nice little edible community where both self-sowed Siberian hogweed (Heracleum sibiricum) and stinging nettle (Urtica dioica) are growing happily in company with Hablitzia tamnoides!

Garden visits with Fosen students

1 Comment

It’s always a pleasure to spend time with students from the Fosen Folk High School from the other side of the fjord. Despite the dreadful weather, we visited all 3 of my sites – the onion garden Chicago at the Ringve Botanical Gardens followed by the Væres Venners Community Garden and, finally, my own garden The Edible Garden (this is the first time I’ve taken a group to all 3 sites!).
Those that took part were two of the “lines”: The Self-sufficiency line and the  The Organic Farming line (small scale).
The Organic Farming line were only on the first two visits, so the picture only shows the Self-sufficiency folk!

Edimentals, Perennial vegetables

Megacarpaea delavayi

2 Comments
This is one of the most exclusive vegetables and finest edimentals out there, Megacarpaea delavayi (Brassicaceae), a plant found in the high mountains of southwest China at high altitudes (3000–4800 m), and one of the most beautiful! Flora of China says it grows in swampy meadows, grassy slopes and open thickets. It also states that it is used for medicine and as a vegetable. Consulting Google Scholar I found a paper “Eating from the wild: diversity of wild edible plants used by Tibetans in Shangri-la region, Yunnan, China” by Yan Ju et al. (2013) which states that the young stems and leaves are used.
I purchased two young plants I found for sale in a small selection of plants for sale at the Gothenburg Botanical Gardens shop in Sweden in 2011. They took two years to flower and set seed in a shady, dry spot in my garden. It is thought that Megacarpaea can be monocarpic (dying after flowering) but it did come back three more years but grew weakly and did not flower again. I therefore moved the plant to a new location in 2016 which was a bad move as it died…
Sadly, I never did get to eat some….
I put the seed I harvested on my seed list two years in a row and sent to a few people, so if you are one of them and have seed, I am very interested! I germinated some of those seed myself (picture), but I don’t recall what happened to them…

Fairchild’s Experiments with Udo from 1914!

3 Comments

Yesterday, I introduced Agricultural Explorer David Fairchild who, inspired from visiting Japan, was determined to try to introduce udo (Aralia cordata) and wrote an interesting paper 120 years ago giving more details about this novel perennial vegetable: 
Udo introduction to the US with cultivation instructions (1903)
11 years later in 1914, he wrote a really interesting report summing up his experiences with udo.  It blows my mind to read how much work was done on this plant over 100 years ago, but sad to see that it was never adopted in a big way! You can read the whole report and I recommend you do, but I’ve picked out some titbits from the report that I found particularly interesting followed by a few other interesting excerpts from various inventories of introduced plants to the US!

Udo introduction to the US with cultivation instructions (1903)

Leave a comment

I stumbled upon this interesting US Department of Agriculture Bulletin from 1903 by David Fairchild, who calls himself Agricultural Explorer, entitled “Three New Plant Introductions from Japan”. There are 4 pages and some photos concerning udo (Aralia cordata)  in the article “Udo : A new winter salad” (see pages 17-20 and the plates in the pdf below). This gives detailed growing instructions for “Kan udo” and “Moyashi udo” for harvesting during winter (October to May); these are cultivation techniques rather than udo varieties. Winter cultivation is more relevant to areas with relatively warm winters.
The other two plant introductions are Edgeworthia chrysantha as a fibre plant (for producing paper) and wasabi (Wasabia japonica).
Kyle Dougherty posted on my Edimentals Facebook group in 2021 about the same program with a great picture of udo cultivation and wrote  “Here’s an interesting story for the udo (Aralia cordata) fans out there. In 1902 the USDA imported some 25,000 improved udo plants into the United States from Japan for trialing as a new vegetable crop. Plants were grown at the experiment station in Rockville, MD until at least 1917, and were also distributed to private gardens around the country and the Chico field station in CA. The Rockville experiment station is long gone, and is now the site of Montgomery College, but I can’t help but wonder if any of these plants are still out there somewhere. It’s also kind of a bummer that it never really caught on despite the effort the USDA put into it.”

Here’s the document I discovered (pages and plates are repeated below)

Wild Enoki, Oca and Hablitzia scrambled eggs

Leave a comment

Wild Enoki, Oca, Hablitzia, wild buckwheat sprouts, Allium nutans  with dandelion, garlic chilis mixed with scrambled eggs for a delicious home grown and foraged lunch!
Enoki is one of the hardiest fungi appearing often midwinter in mild winters. Also known as velvet shank (vintersopp in Norwegian, meaning winter fungus; Flammulina velutipes). Many had been reporting finding this species recently, and I too found some when I visited the botanical garden the other day! It’s difficult to believe that this is the same fungi as Enokitake or Enoki, sometimes offered in supermarkets and one of the most popular cultivated fungi in the Far East. The cultivated fungi are long and white as they are grown in the dark in an enriched CO2 environment which gives longer stalks.

Seven Vegetable Dishes

Leave a comment

In Denmark’s major ethnobotanical work, Brøndegaard’s Folk og Flora (1978-80), ground elder (skvalderkål; Aegopodium podograria) is one of seven different greens used in a once common health-bringing springtime dish, skærtorsdagssuppen (skærtorsdag=Maundy Thursday) and I included this in my book as a number of perennials were among the ingredients as they are at their best around Easter when this dish was served:
The number 7 is considered lucky in different cultures around the world and is often seen as highly symbolic. This Danish dish is related to the northern England dish Dock Pudding, which has very similar ingredients (see Easter Ledge Pudding in my book Around the World in 80 plants).

After my book was published I came across another seven vegetable dish from Japan, nanakusa, which contains an unusual mix of edible plants (see the first slide below – from my talks over recent years) including perennial Oenanthe javanica (seri) and as fate would have it, on my study tour to Japan, organised by my friend Aiah Noack, I was taken to a farm where they were actually producing several of these herbs (pictures below). Greenhouses full of common chickweed (Stellaria media; vassarve) was a sight I won’t forget easily! Today, 7th January, is the Festival of Seven Herbs or Nanakusa no sekku (Japanese: 七草の節句) and is the old Japanese custom of eating seven-herb rice porridge on this day.

As I was writing this I wondered if there were other seven herb traditions  out there and, right enough, a quick google search revealed two others (please let me know if you know of others):
Seven vegetables on the seventh day of the Chinese New Year is eaten for luck and health, a tradition perserved by the Teochew or Chaoshan people in Southern China. The following five vegetables must be included, the other two are flexible: celery, garlic, green onions, coriander and leeks.
Seven vegetable couscous: Seven is a lucky number in Jewish tradition and a dish featuring seven vegetables is a New Year favourite among Sephardic Jews (early autumn). A recipe can be seen here: https://theveganatlas.com/seven-vegetable-couscous

 

Dandelions, Perennial vegetables

Geeking out with Dandelions

Leave a comment

Earlier this year I bought the Field Handbook to British and Irish Dandelions by A.J. Richard which contains descriptions, photos and keys for all 239 known UK and Irish species, a book written during Covid lockdown! I was curious to go deeper into the world of dandelions and to hopefully identify the various species I have in my garden and area around apart from the obvious moss-leaved dandelion (is this really Taraxacum sublaciniosum?), the pink flowered dandelion (Taraxacum pseudoroseum) and white-flowered species like Taraxacum albidum. And what about some of the historical cultivars such as the French cultivar “Pissenlit Coeur Plein Ameliore”. What species is this?
Inspired by the book, I set about taking detailed photographs of about 40 different dandelions at home and at the Væres Venner community garden with the thought to have a proper look and try to key them out during the winter months. I did try one species but it was daunting and they may not be species found in the UK. I have introduced quite a few cultivated and wild Taraxacum species in the garden over the years. I also joined a couple of specialist Taraxacum groups on FB. There I met Alex Prendergast in Norwich who kindly sent me seed of 25 mostly identified species! Having the answer for species that I could grow and have before me should hopefully help me keying out some of my species! I finally got round to sowing these dandelions today; see the album below. At the very bottom are detailed pictures for one species, the moss-leaved dandelion, which I’ve learned are necessary for dandelion identification.

Grape leaves

Leave a comment

I love it when edible plants find their own place in my garden! I planted a hardy grape species Vitis coignetiae from the Far East including Japan, Korea and the Sakhalin. At least, I think this is what it is as I don’t have any records of planting it. I think it originated in a plant sale or cutting from the Ringve Botanical Garden in Trondheim who have a large plant covering the whole wall of a garage. This also produces small fruits which are being increasingly used for wines in Japan (and some breeding is also being done); see the Japanese wiki page: https://ja.wikipedia.org/wiki/%E3%83%A4%E3%83%9E%E3%83%96%E3%83%89%E3%82%A6. This species is dioecious (male and female flowers on different plants), so I guess there is more than one plant at Ringve and there’s little chance of mine producing fruit. 
I planted it originally in a shady spot at the corner of the extension (low roof in the picture) some 20 years or more ago. Today there are no leaves or vine above the original planting spot and a vine creeps about 5m from the root horizontally on the ground along the house wall, rooting, along the way, and climbs up into the yew tree I planted next to the house for the birds in winter. The grape has finally reached the top of the yew this summer and is the leaves are almost smothering the yew!

The vine running along the house wall!

I’m inspired by Eric Toensmeier’s work on the nutrition of perennial vegetables and specifically his article “The most nutritious perennial vegetables for cold climates” (see https://www.permaculturenews.org/2021/06/21/the-most-nutritious-perennial-vegetables-for-cold-climates) to use the leaves of my grape for more than the occasional wrapped dish. The taste of the leaf is good raw!
Eric wrote about cultivated grape leaves: “Grape leaf (Vitis vinifera). Worth eating for nutrition and not just because stuffed grape leaves are delicious. Extremely high in fiber, very high in calcium, magnesium, and Vitamin A, and high in Vitamin E.”
I did find a comment that the shoots of this species are eaten in Japan.
