PEAK PERENNIAL VEG TIME AT RHS WISLEY

A series of pictures taken of edible plants that I spotted in the “ornamental collections” at RHS Wisley Gardens on 11th April 2024.  Admittedly, some will be obscure or “emergency food” edibles, but all have been used somewhere for food and have an ethnobotanical story to tell!

I was also shown around all the great work being done by the Wisley Edibles Team later the same day; see

Dandelions in pink, white and yellow

16th May 2024: Dandelions in white, pink and (self-sowed) yellow in the Asian part of the World Garden at the Væres Venner Community Garden in Trondheim. I planted both Taraxacum albidum, Taraxacum leucanthum and Taraxacum pseudoroseum in this part of the garden and suspect these are albidum and pseudoroseum but am not sure. Will post separate albums below showing detailed studies of the pink and white one in case anyone has a key to these (there are several white flowered dandelion species in Asia).

Botanical details of what I’m growing as Taraxacum pseudoroseum in the World Garden at the Væres Venner community garden in Trondheim:

EDIMENTALS REACH MAINSTREAM HORTICULTURE

My attention was drawn today to two articles in which my word Edimentals featured (made up in the late 2000s):
EDIMENTALS AT CHELSEA FLOWER SHOW
“Edimental plants that are both edible and ornamental have emerged as a star of the Chelsea Flower Show.”
The article from the Daily Telegraph about this year’s Chelsea Flower Show can be read in the 3 pictures! 
The second article had actially been published last year on the BBC Food site. Here’s the link to “The low-maintenance edible garden for lazy gardeners” which both mentions Edimentals and credits me with the word!

Megacarpaea delavayi

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…

First 2023 Edimental Flowers

Despite the fact that the soil is frozen solid apart from the top couple of cms, I was surprised to discover the year’s first flowers in the garden: 
1. I received this as Primula veris subsp. macrocalyx but is always a couple of months earlier than Primula veris, so I wonder if it’s a hybrid?

2. Primula elatior (oxlip / hagenøkleblom) – this could also be a hybrid

“Over the top” Flowery Whopper Carrot Salad

I was going to post an album of pictures showing off all the late flowers in the garden this record-breaking mild autumn still without any frost, but as they’re all edible I made a salad instead!
There were 33 different edible flowers (see the list below the pictures) plus 30-40 greens and a whopper carrot which I decided to keep whole as a feature! It was cut up when the salad was tossed afterwards. It has a story too as it is one of the Danish accessions rematriated from Seed Savers Exchange (SSE) in the US last winter. I took a few seed before sending the rest on to Danish Seed Savers (Dansk Frøsamlerne). It’s called Kämpe which means Giant in Swedish/Danish (I call it Whopper as it’s probably the biggest/thickest carrot I¨’ve grown here). It’s not a very old variety and SSE informed that it was a cultivated variety originally from the Swedish seed company Weibulls. Anyone know more about it?

Flowering Aster scaber

September is the month when several Asteraceae are in flower including one of my favourite perennial vegetables and edimentals Aster scaber (yes, I know it’s officially Doellingeria scabra) or chamchwi in Korea where it’s cultivated commercially for Korean markets around the world (often sold dried). It’s also popular with pollinating insects as can be seen in the gallery taken this week here.

….and a parasitic wasp on the flowers:

 

See this page for more links to articles about this plant on this blog: https://www.edimentals.com/blog/?p=6080
It’s also one of the 80 in my book Around the World in 80 plants.

Sweet Gigas stalks

Somebody asked me a few days ago if one could eat Angelica gigas (Korean Angelica) as you can Angelica archangelica (see my book Around the World in 80 plants for more about that). In my book, I do mention gigas as one of several other Angelica species used in other parts of the world, but until yesterday I hadn’t eaten it myself, partly as I¨’ve never had many plants and the flowering is wonderful!!


On the Korean wiki page, it simply states that “dangwi / dangquai’s petioles and tender stems are eaten raw or seasoned with herbs”. The root is also used medicinally along with Angelica acutiloba and Angelica sinensis.
You can find various instructional videos and recipes on Korean pages by searching
For example, the spring leaves and petioles are boiled and served with onions, garlic, sesame oil and sesame seeds.
As my plants were close to flowering (they darken quickly to deep red at this stage), I decided to go for using the flower stems in salad:I first took one of the thicker flower stems…
….and sliced off a bit at the base for a taste! I was taken aback by how sweet it was (flower stems of Angelica archangelica were in the past considered to be candy by Norwegians). This reminded me of other plants that have surprisingly sweet flower stems: Scorzonera hispanica (scorzonera / scorsonnerot) and Arctium (burdock / borre). I assume that as plants like these approach flowering they produce less insect repellent chemicals and transfer their energy to producing flowers and seeds. For the salad, I peeled off the outer layer as it is fibrous and sliced it into the salad.  Young seed pods of sea kale / strandkål were also available as were Scorzonera flower stems and buds.



As with most Apiaceae, Angelica gigas is very popular with the pollinators, so this one definitely fits into the Edi-ento-mental category (delicious, ornamental and popular with the pollinators – what more could you wish of a plant!).
Unfortunately, like Angelica archangelica this species dies after flowering.

Chiugok, Small Bird’s Garlic, a hardy Himalayan edimental

Like Sherpa onion or Nepalese onion Allium wallichii, which features in my book Around the World in 80 plants, chiugok (small bird’s garlic) as Allium macrantum is known in Lithang, Tibet is the latest emerging Alliums in my garden. I often wonder if they are still alive when, in a cold spring they haven’t emerged by the end of May, but both species have overwintered now for almost 20 years.

A nice large group of Allium macranthum in the Gothenburg Botanical Gardens in Sweden on 26th May 2008
Spring shoots in the Tromsø Botanical Gardens on 4th June 2009

I’m not sure where my oldest plants came from but my second accession came from Vojtec Holubec’s seedlist, collected in Szechuan in China.  It’s native to Bhutan, Sikkim, Gansu, Shaanxi, as well as Szechuan and Tibet and grows in wet places at elevations of 2700–4200 metres (Flora of China).

The roots are fleshy and could no doubt be eaten like the fleshy roots / rhizomes of Allium wallichii and Allium hookeri are.
The roots of Allium macranthum (on the left) are similar looking to larger Allium wallichii (right)

By early July the old roots are withering away and new roots are growing as the flower scape appears:


The flowers are gorgeous hanging on long pedicels. Note that the flower colour varies and the Szechuan accession is pink with green pedicels and has relatively many flowers.

Ethnobotanical records
I searched Google Scholar for evidence of Allium macrantum being used traditionally for food and there were indeed a few ethnobotanical studies recording its use as a food plant. Although not the most popular food Allium in the Himalayas, it is reported to have been one of several species eaten both in Arunachal Pradesh in North East India, the Eastern Hills of India (along with more commonly used Allium wallichii, Allium hookeri and Allium fasciculatum) and used as a spice with meat in South Central Tibet. In Lithang, chiugok “is cleaned and cut into small pieces. It is mixed with butter, tea, roasted barley flour (tsampa), salt, and chilly. Tsampa may not be added. The sauce so obtained is eaten with Tibetan dumplings (mokmok) and fried meat-filled pancakes (shapakle)” (in Traditional knowledge of wild food plants in a few Tibetan communities). 
The taste is in my experience relatively strong and therefore best in mixed salads and cooked dishes.
Allium macranthum has also been moved into gardens as an ornamental and has also been used medicinally, including,  along with other Allium species, as a cure for altitude sickness!
