A diversity of rat’s tails

I remember years ago ordering seed of a special heirloom heritage radish “rat’s tail” (Raphanus sativus var caudatus) through the Heritage Seed Library in the UK. I remember that it was the gardener at naturalist Gilbert White’s House and Gardens at Selbourne in Hampshire that offered the seed and I remember that we ended up trading seed as they were looking for plants that Gilbert White mentioned; see  https://gilbertwhiteshouse.org.uk/gilberts-gardens 
The resultant plants had long green pods. However, I lost them eventually.  Subsequently I’ve tried seed of rat’s tails several times and the pods have never been as long as those original plants. 
Radishes are difficult to grow here in spring as our long days result in them quickly bolting (still looking for a good day neutral variety). I remember reading that when wild radish Raphanus sativus was originally domesticated in China that it was for the young seed pods rather than the swollen tap roots. 
I therefore decided this winter to source various rat’s tail radishes from commercial sources and also obtained seed of 4 (of 8 available) accessions from the German genebank IPK Gatersleben. There was no available descriptons, so this was a random selection. They were sown in May in the World Garden (Verdenshagen) at the Væres Venner Community Garden (NB! I do grow a few annuals on the world garden if they have an interesting geographical story associated).
Yesterday I harvested a few of each and was blown away by the diversity with long red, thin green and two more stumpy varieties like I had been getting in recent years when ordering rat’s tails. Below is what Cornucopia II says on this interesting vegetable. 
Assuming like me that you will want to grow your radishes to seed for the following year, the land is occupied all season in any case, so rat’s tails produce more than root radishes. The flowers are also also rather pretty bicoloured pink and white and area also attractive to pollinators! I think I will save seed and deveop a mixed grex of these and more varieties from the gene bank next year!
And this gave the opportunity for a unique rat’s tail salad for lunch with radish flowering tops too, also delicious (see the pictures at the bottom) :)

Local runner bean landrace

I’ve started work on a local landrace of runner beans / blomsterbønner (Phaseolus coccineus). I sowed yesterday 15 varieties that are the earliest varieties I could find from commercial suppliers and the German genebank IPK Gatersleben! Runner beans are marginal here, only ripening with warm frost-free autumn weather, preferably against a warm south facing wall!
Thanks to Raphael Maier who told me that the IPK Gatersleben have phenological data for part of their collection of over 400 runner beans. I therefore looked for early flowering and early ripening data when selecting varieties.
The assumption is that it will eventually get warm enough to plant them outside at the community garden Væres Venner where I will run the trial! Currently still only maximum 8C and the 10 day forecast shows much of the same with low pressure dominated weather and only a slight increase to 10C.

Selecting for a local early broad bean

I sowed broad (fava) bean / bondebønner (Vicia faba) seed indoors yesterday as there’s still snow where I’d planned to put them outside. In addition to my late broad bean grex with a mix of colours, I thought it would also be worthwhile to start developing a local early variety which could also potentially be useful in more marginal areas such as North Norway and mountain areas. I’m starting with 4 early varieties, two from IPK Gatersleben: 1) Expresse Zeer Vroege Witkiem (meaning “very early white germ (seed)” (FAB424), Express (FAB 7066), my own selection of the commercial variety Express which I’ve grown as my early sort for some years and another purportedly early variety De Monica from Chiltern Seeds. I’ll select mainly for earliness and seed size.




Moss-leaved dandelion = Taraxacum tortilobum

I’ve been trying to find out what species the legendary moss-leaved dandelion (as featured in my book) and some other cultivated varieties actually are. I took the series of detailed pictures below of this plant last spring and posted them on the Dandelions of Britain and Ireland group (there are several experts of Taraxacum there including author of the Field Handbook to British and Irish Dandelions, John Richards)
Dutch expert Karst Meijer has ID’d the plant as Taraxacum tortilobum. We cannot be 100% sure that this is the original plant depicted in the Vegetable Garden (1920), but it makes sense that it was a wild plant that was domesticated as dandelion breeding is difficult as they are largely apomictic. T. tortilobum is found in the wild in northern France, which strengthens the theory that this is the plant. See https://www.gbif.org/species/5394131 where it is known as the twisted-lobed Dandelion.
The plant I grow which is the only line claiming to be the moss-leaved dandelion originated from IPK Gatersleben (German genebank) as Taraxacum sublacionosum “Delikatess” which it isn’t!

Unusual October veg

A few unusual vegetables this October from the Edible Garden and House:
1. I’ve been trialling around 20 different chicories this year from seed from the German seed bank IPK Gatersleben. This is one of the best producers, Sugar Loaf (Accession CICH 350) which ended up in yesterday’s Basella and Chicory pizza! I remember years ago on a work meeting in Venice enjoying a chicory pizza.

2. Gunnera tinctoria is the representative for South America in my book Around the World in 80 plants. Sadly, it is not very hardy and mine grows in a large pot half submerged in my small pond and is moved into the cellar for the winter where it goes to sleep for most of the winter. The edible leaf petioles don’t reach the size of plants grown outside and are therefore a bit more fibrous. Their crunchy texture and sweet-sour taste was nevertheless a good addition to a mixed salad earlier in the week.  
3. This summer was the first time I’d grown Okinawan spinach (Gynura bicolor). I cut it down earlier this week and used the leaves in the mixed salad together with the Gunnera. It’s the variety with red undersides to the leaves. Thanks to my friend Kim Jacobsen who leads KVANNs Stueplantelaug (Norwegian Seed Savers’ (Edible) House Plant guild) for sending me cuttings. It looks and tastes good!

4. I also grow Basella (Ceylon spinach) inside and it always produces berries and seeds for the following year and for sharing. This was used with the chicory (above) in the pizza.


5. Autumn is also the time that the perennial kales resprout and provide an abundance of greens. Here’s a video of the perennial kales in the Edible Garden this week. I have another similar sized plot at the community garden.

6. One of my favourite wild edibles is common sow thistle / haredylle (Sonchus oleraceus), although I deliberately cultivate it. However, apart from posts by myself, this is a plant that isn’t mentioned in Norwegian foraging groups in Norway. Is this because it needs some preparation in order that it’s merits can be properly understood, the bitterness maybe putting people off at first taste? This is a plant I devote several pages to in my book Around the World in 80 Plants and I document how this is an important wild edible worldwide. My introduction to its merits was in the book Native Edible Plants of New Zealand by Andrew Crowe and on a work trip to that country in the early 2000s I could see for myself how important this plant is for the Maori people with over 1/3 of all the vegetable stalls selling this plant. Known as puha to the Maori, it has become a so-called cryptocrop* of the Maori vegetable gardens, an annual “weed” introduced by the Europeans with a similar taste to the traditional perennial endemic sea-cliff inhabiting puha (Sonchus kirkii). Annual puha is encouraged in between the main crops as it has a cash value and increases the yield of the land. It has also been suggested that the large consumption of annual puha by the Maori (hardly used by people of European descent) protects them against some forms of cancer. I was so inspired by the story of how a plant much hated worldwide could at the same time be a superfood appreciated by the Maori and all the other peoples around the world who are in the know, that I introduced it to my garden and it is now become my most important vegetable from late July to the first frosts! From it becoming a burden to weed out this coloniser of open soil, I now weed this “weed” leaving only a few plants to grow strong on the edges of my vegetable beds….and hate is turned to love! Much more in my book!
*Crytocrops: a distinction has been made between cryptocrops
from weeds by Diego Rivera et al. in a 2006 paper: “This led us to distinguish cryptocrops from weeds. Both are not cultivated plants living in crop fields and competing with the main crop. The fundamental distinction is the intensity of gathering by man”.
7.  I have a special fascination for vegetables that are superstars in one part of the world but hardly known in their area of origin and one of those is garland chrysanthemum or crown daisy (Glebionis coronaria, early known as Chrysanthemum coronarium). This is a wild and extremely common flower of early spring in Mediterranean countries, often growing in large quantities, and commonly available in supermarkets in Japan where it’s known as shungiku. See more on this blog post Shungiku soba (a standard offering in soba restaurants in Japan): https://www.edimentals.com/blog/?p=22710
There is a legend that Marco Polo introduced pasta to Italy from China. In an article “Fra Malta til Japan og tilbake” (From Malta to Japan and back again) that I wrote 15 years ago for a Norwegian herbal magazine Grobladet in 2006, I suggested that Mr. Polo gave chopsuey greens in return (see and download the article here https://www.edimentals.com/blog/?page_id=3493).
When I first wrote about shungiku in 2006, I could only find one reference of its use in the Mediterranean for food. Since then, there have been carried out numerous ethnobotanical studies throughout the Mediterranean and a quick search carried out now revealed that this plant has been used traditionally throughout the area, although by no means a common wild edible:
In Turkey: numerous studies (leaves, young shoots and stems are used) have recorded this plant used as summarized in a paper from 2019 by İsmail Şenkardeş and others: “An Ethnobotanical Analysis on Wild Edible Plants of the Turkish Asteraceae Taxa”
In addition, it is recorded in two studies in Spain, in Morocco, Palestine and in Sicily it was both cooked and used in salads.
This plant fits nicely into my diversity cooking as it produces new shoots in smaller amounts throughout the summer from July to the first frosts and they are usable even after the plant has flowered and produced seed.
There are many cultivars with different flower colour, double and single and serrated and whole-leaved forms. I’ve grown some 10-15 different cultivars this summer, the seed from the collections at IPK Gatersleben in Germany.





Winter seed sowing and recording

Here’s how I sow and record perennials sowed mid-winter for stratifying. They will be left outside until they germinate in April-June, some not until 2020!
