Centro d’Ompio and Pettenasco

On 2nd April 2018, Matthias Brück who had invited me to Switzerland to take part in the Perennials for Resilience seminar in Stans asked me along on a trip through the Alps to the Piedmont area of NW Italy! This is the first of three blog posts about this trip to an area that I think one day Matthias and his good lady Katharina will have a big impact in this area! This is also written as a thank you to Centro d’Ompio’s founder Pius Leutenegger who invited us to stay at the centre, wined, cheesed and dined us and took us on a wonderful tour of gardens and nature in the Lago d’Orta / Lago Maggiore area! I hope to come back one day and repay your kindness in helping developing the Centre’s gardens and maybe holding a course to start the process!

Beacon (Camas) Hill, Victoria BC

After the Indigenous Plant Walk the day before, my Airbnb hostess Kelly Kerr invited to show me around the Beacon Hill Park, a 200 acre mix of both natural areas, formal flower beds, but above all else the site is of great cultural significance to the Lekwungen People (now known as Esquimalt Nation and Songhees Nation). In fact, the City of Victoria has adopted 2017 as a Year of Reconciliation, and a traditional longhouse will be built on a hilltop site! When the British arrived they wrongly assumed that the open meadow landscape was “natural” and unused. In fact, the Lekwungen had cultivated and maintained these shrub-free grasslands for centuries. The meadows were worked to grow camas which was their most important root crop, as well as other edible wild plants. Both common and great camas (Camassia quamash and Camassia leichtlinii) were used. This habitat was reminiscent to the English of the ideal 19th century parkland landscape that they recognised from home and was instrumental in Victoria being founded at this site!
The Beacon Hill area was apparently “one of the most productive camas territories on Vancouver Island,” The Lekwungen people both harvested bulbs for their own use and also traded with other west coast peoples. Thankfully, it is now likely that these productive and butterfly rich grasslands will be gradually restored. The album of pictures were taken in the park and along the adjacent shoreline where native families would arrive in the past for the harvest. They would harvest the bulbs in summer when the seed heads were ripe. Only the largest bulbs were harvested and the others replanted. Invasion by shrubs was minimised by regular burning. Each family had its own designated area. The practice of farming natural areas in this way was commonly practiced around the world by native peoples.

Around the world with Erythroniums

Erythronium japonicum, katakuri in my garden

As an introduction to two soon to be published blog posts concerning visits to two nature reserves in Japan during the mass flowering of katakuri (Erythronium japonicum) in early spring 2016, here is a short around the world with edible Erythroniums review, with an album of pictures of various species and varieties that I’ve grown here in Malvik together with pictures taken in various botanical gardens!

Known in English variously as trout or fawn lilies (on account of the spotted leaves) and dog’s tooth violets (not related to violets, the bulbs resembling dog’s teeth), there are some 25 species found in North America and Eurasia…

There are a number of species in North America, several, if not all of which were used by Native American tribes. In Daniel Moerman’s Native American Ethnobotany (http://naeb.brit.org), 5 species are documented as used for food, with yellow flowered E. grandiflorum (Glacier or Avalanche lily) with most records, including: “Bulbs eaten raw and cooked, dried for winter use; small root ends of corms eaten as candy by children; made into a pudding by boiling black tree lichen, dried saskatoons (Amelanchier), salmon eggs, lily bulbs, or bitter root (Lewisia) and deer fat”. Other species for which the bulbs were either eaten raw, baked, steamed, cooked and (sun)dried for later use are E. mesochoreum, oregonum and revolutum. An interesting technique was to chew the root and spit it into a river to make fish bite (trout, I presume ;) ). One informant says, however, that the raw corms were poisonous (but there are many records of them being eaten raw). Erythronium oregonum bulbs were, according to ethnobotanist Nancy Turner, an important food for the Kwakiutl people on Vancouver Island in Canada. They were eaten raw, baked, boiled, or dried.

The best North American modern firsthand account is as usual that by Samuel Thayer in his wonderful book Nature’s Garden. He notes that the species he uses most is woodlander Erythronium americanum, not documented as edible (only medicinal) by Moerman. He rates the early spring bulbs highly, tasting “ like sweet corn or snow peas..crunchy, sweet and tender raw”…but he notes that they are small and it takes a lot of effort to pick a decent amount (he also notes that E. grandiflorum bulbs, a species that grows in alpine meadows, are bigger). Various early foraging authors in the 50s and 60s, including Euell Gibbons, note that the leaves, flower stalks, buds and flowers of americanum are eaten raw and cooked. Thayer is not fond of the leaves or flowers, however, saying that they are “best before unfurled…bitter aftertaste…worse after cooking”, but he comments that others enjoy the taste.  I haven’t noticed any bitterness the times I’ve tried different species. Gibbons also mentions that white trout lily (E. albidum) has similar uses to americanum.

The species that grows best for me is dog’s tooth violet Erythronium dens-canis. This species was once considered to range from Southern Europe to Japan, but the Eastern forms are now considered to be separate species, E. sibiricum and katakuri (E. japonicum), both of which I grow, but clumps grow very slowly, if at all! In Sturtevant’s Edible Plants of the World (1919), it’s stated that the Tartars collect and dry the bulbs of dens-canis and boil them with milk or broth. Cornucopia II informs us that “Roots eaten with reindeer’s or cow’s milk in Mongolia and Siberia. Leaves boiled, starch from roots..” (presumably this is what we now know as sibiricum).

Ken Fern in Plants for a Future recommends E. “Pagoda” and “White Beauty” as they “grow freely when well-sited” in the UK.  Alan Carter in Aberdeen has firsthand experience and on a good blog about Erythroniums for the forest garden (see https://scottishforestgarden.wordpress.com/2013/07/06/eating-dogs-tooth-violet) rates “Pagoda” as the best one to grow for eating, due to its larger bulbs and states that “My favourite way of cooking them is to slice them thinly across and fry the discs”.  Pagoda is a hybrid between Erythronium tuolumnense and Erythronium californicum ‘White Beauty’ and is readily available.

All the North American species I’ve tried including Pagoda have sadly not survived more than a few years at best in my garden.

As mentioned, Erythronium japonicum will be the feature of two follow-up blogs and I will discuss this one more later, but the bulb starch, known as katakuri-ko, was important and harvested from the wild in the past in Japan,  but nowadays potato starch is used in its place as the wild stands are considered by some to be under threat, not only dug up for food but also removed from the wild for the ornamental plant trade… We will also see that both the leaves and flowers are used in Japan. If using leaves, it’s best to only one of the two leaves produced each year so as not to weaken the stands too much.
