This year’s udo (Aralia cordata) selfie pictures, probably the highest ever with a flowering spike way above my head. I harvested about 1/3 of the shoots in the spring. This is my largest herbaceous perennial vegetable that was planted here 20 years old ago! It has never had any fertiliser and is growing on the steepest slope in my garden. Ostrich fern (strutseving) and giant bellflower (storklokke) can be seen in the foreground.
This is the title of an 11 page article on my garden in a new Austrian book on edible forest gardens and agroforestry systems by permaculturist Bernhard Gruber. I wish I could read German! I briefly met Bernhard who attended my talk in Graz, Austria in January 2020.
A year ago, on 22nd September 2019, Joe Hollis had invited me to do a walk and talk with him at his Mountain Gardens in North Carolina! Before the event he took me around the woodlands to show me the woodland flora. I made a short video at most of the plants to help me remember what they were. I’ve now put them together into one video (see below). Joe talks briefly about the following plants: Disporum spp. (trachycarpum?) (medicinal) Medeola virginiana; Indian cucumberroot Hosta sieboldiana (self-seeding) (food) Panax quinquefolius; American ginseng Prenanthes trifolioliata; Gall of the earth (Food and medicine) Smilax rotundifolia; common greenbrier (Food and medicine) Acer spp.; maple Castanea spp.; chestnut Sassafras albidum; sassafras (Medicine and beverage/spice) Cacalia delphinifolia? (Far Eastern edible and medicinal) After the video is a gallery of photos taken on the same tour. Will post more from the walk and talk later. This is one of several blog posts about my visit to Joe.

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.
It’s always a nice surprise to discover a plant in flower in the garden that I thought long dead! Yesterday I discovered a plant that I’m pretty sure is Ornithogalum pyramidale (Pyramidal star-of-Bethlehem). I planted 8 two year old plants in this location in 2016. This species is used in a similar way to Bath asparagus (Ornithogalum pyrenaicum) as I wrote in my book: “There are at least three other similar species used in a similar way in the Mediterranean, Ornithogalum narbonense (mainly in eastern parts) and O. pyramidale and O. creticum (Dogan et al., 2004; Rivera et al., 2006).” I’ll have to rediscover it a bit earlier next year!
A new species in the garden this year is the Pacific waterleaf or slender-stem waterleaf ( Hydrophyllum tenuipes) from California, Oregon, Washington and British Columbia. It was a food plant of First Peoples on the West Coast. Mine came courtesy of the Gothenburg Botanical Garden.
Indian salad or Virginia waterleaf (Hydrophyllum virginianum) is also currently in flower and features elsewhere on this blog, being one of my favourite spring salad plants and one of the 80 in my book Around the World in 80 plants.
I’ve failed several times to establish Hydrophyllum canadense, the species I’d expected to be easier. The other I grow is Hydrophyllum appendiculatum which is biennial and not yet in flower.
English: This is the course for you who want to learn more about perennial vegetables and forest gardening in a course held in and around Norway’s world-renowned Edible Garden, now one (of 4) Permaculture Land Centres in Norway, led by author and head of KVANN / Norwegian Seed Savers, Stephen Barstow. There will be lectures on Allium, an extended garden walk, making lunch and dinner with spring harvested produce, foraging on the shoreline and the ostrich fern tour along the Homla river canyon. Full program, pictures and link to pictures in the pdf at the bottom

Course fee and registration: You must either be a member of KVANN or the Norwegian Permaculture Association. NOK 1600 (for the whole weekend) for KVANN members (membership costs NOK 250), NOK 1800 for members of the Norwegian Permaculture Association. Kr. 900 for students and unemployed. There is a binding registration when paying the course fee. VIPPS to 91529516 (private). Bank account: 82306086762.

I’ve harvested seed of a distinctive tall oriental woodlander this week, Parasenecio hastatus. It’s taller than I am and reminds me of some of the tall Lactuca species I saw in North America recently, perhaps growing in similar habitats in the Far East.
It’s a wild species in China, Japan, Korea and the Russian Far East. My most comprehensive Japanese foraging book says something like this (thanks to Chris Sonnenschein for the translation): “shoots are harvested when 20-30 cm long. Then when ready to cook, like asparagus, break/snap the shoots with your hand and discard the more woody end. Dice up the remainder into chunks. Boil in salted water. Rinse. Parboil in normal water just briefly. Eaten with Bonito flakes (fish), Soy Sauce & Mayonnaise. Also the leaves from the new shoots (this year’s growth) can be eaten, especially as tempura, through summer”.
It always amazes me how edible plants in my garden find their own best companions andystem create together really productive microsystems, often on really marginal parts of the garden that I never imagined could be so productive, such is the magic of perennials!
Here are a couple of videos showing two of these areas:
The edge of what was a shady bed previously used to grow annuals. I planted Hosta sieboldiana and Rumex scutatus on the edge of this bed with an Onoclea sensibilis (sensitive fern / perlebregne), one of the species sometimes eaten as fiddleheads. The shade encouraged first a Hablitzia to self-seed and next to it a large stinging nettle. A siberian hogweed (Heracleum sibiridum) also found a place in the mix! Perennial kales are growing on the rest of this bed this year! The video starts with the flower umbel of a pink flowered Heracleum sphondylium (common hogweed):
The second area is at the end of one of my originally annual beds where I struggled to grow vegetables as it was very dry and under the shade of a large birch tree. Here I planted a number of Hablitzia plants 12 years ago and they love this spot producing good yields and climbing up into the birch tree in summer with the help of stakes I provided for them. Now, hogweeds have moved in (self-seeded), both Heracleum sibiricum and H. sphondylium and the Hablitzia is now using the 2.5m high hogweeds as climbing support!
