Nettle-leaved bellflower

Nettle-leaved bellflower (Campanula trachelium) has a more southwesterly distribution in Europe than my favourite giant bellflower C. latifolia and replaces the latter species in the south of England, France, Italy, Spain and North Africa and eastwards into West Asia. It has also widely naturalised in northeast North America. Like C. latifolia, it has edible sweetish tasting roots that contain the carbohydrate inulin like Jerusalem artichoke, good for diabetics, but can give flatulence. I suspect, however, that it takes several years to get to a usable size. I’ve been digging over an area of the garden into which Polygonum alpinum (Alpine knotweed) had invaded this week and there were also many self-seeded bellflowers with good sized roots, so I put them to one side to use in a delicious zucchini-bellflower curry which we ate last night!

Nettle-leaved bellflower has similar habitat requirements to the giant bellflower, inhabiting open woodlands and hedgerows and grows well in complete shade on the north side of my house amongst the Hostas. It has a preference for alkaline soils and grows well on clay. It is therefore an excellent plant for the forest garden, although given the choice I would prefer the giant bellflower as the spring leaves of trachelium are coarser and hairier and therefore less good in salads, but nevertheless fine finely chopped in mixed salads.  It has been used traditionally in Italy in mixed species spring soups such as minestrella (see page 59) and is one of the ingredients in pistic (boiled and fried, see page 59 of my book Around the World in 80 plants).

There are a number of ornamental forms available in the trade which you might like to try, including a single-flowered white form (var. alba), which has naturalized in my garden. The double white (‘Alba Flore Pleno’) form and “Snowball” (https://dorsetperennials.co.uk/product/campanula-trachelium-snowball) haven’t come true from seed for me. ‘Bernice’  is another deep purple-blue flowered cultivar.

Garden wild green soup

Last night we made a green pea soup and apart from the Hablitzia (Caucasian spinach / stjernemelde), I used perennial vegetables growing in a wild part of the garden. With little or no help from me there’s a bounty of wild edibles in this area under wild hazels (Corylus avellana) and this made for a delicious pea soup with masses of greens. 
Campanula latifolia is documented as used in spring soups in the 16th century in my area in Norway and Heracleum shoots are also a tradional soup ingredient, in particular Russian borsch now thought of as a beetroot soup was originally made with hogweed shoots.

Naturalised Giant Bellflower

No doubt introduced by the previous owners here as an ornamental and despite the fact I spent a lot of time trying to eradicate it from parts of the garden, Campanula latifolia (giant bellflower / storklokke) is nowadays one of my most important springtime vegetables used both cooked and raw. It has naturalised under Hazel in part of the garden! Always nice to see how plants find their own way to the best spots it grows happily alongside Aegopodium podograria (ground elder / skvallerkål). See the excerpt from my book Around the World in 80 plants below. Here is the excerpt from Around the World in 80 plants (I’m happy to send signed copies within Norway). “When I first moved to my present garden, there was one weed that I struggled to eradicate from my cultivated beds, Campanula latifolia or giant bellflower. The roots in particular were almost impossible to dig out, having a knack of germinating in the most difficult places. Then, one day I was reading the Norwegian book “Gratis Mat av Ville Planter (Free Food from Wild Plants; Holmboe, 1941). I learnt that my worst weed had been wild gathered for food by farmers in my area in the 17th century, a tradition which probably died out soon afterwards. The leaves and stems were collected in springtime and made into a soup. Similar stories have also survived from other parts of Norway and Sweden. Storklokke (literally large bell) is considered to be one of the most commonly used wild food plants in the past in Norway. Both the leaves and roots were used, the latter also ground and added to bread.”
It was the nephew of Bishop Gunnerus (after whom the genus Gunnera was named) who published this in Norway’s first flora published 3 years after the Bishop’s death! It was stated that “storklokke” deserves to be considered as one of the best springtime greens! I totally agree! Thanks to the previous owners (Johansen) for planting it for me!




 

Bellflower-chokes / Storklokkeskokker

I’ve previously introduced the gourmet part of the dandelion, the dandichoke! I write in my book:
My favourite foraging author “(Samuel Thayer’s) favourite dandelion vegetable is what he calls dandelion crowns, as named originally by Euell Gibbons (1961). I prefer to call them dandichokes, as both these and artichoke hearts are located below the flowers. In the early spring, the very young flowers appear at the surface. The dandichoke is just the self-blanched crown between the top of the root, which is a bit below the surface, and the developing flowers. Although small and difficult to clean, they are very tasty”. See the picture below!

The same applies to another of the 80 in my book, Giant Bellflower (storklokke) which also has a delicious (sweet tasting) self-blanched stem between the root and the surface….bellfower-chokes or, even better in Norwegian, storklokkeskokker! I discovered this accidentally last year! I had earlier noted in my book the sweeter tasting spring shoots after blanching (covering to excude light).
