Sea kale Crambe maritima is sometimes referred to as the King of the Vegetables (Queen is perhaps more fitting!) . This is partly due to the fact that it was in the past cultivated in heated greenhouses for nobility in the UK for Christmas! Maybe not the King, it is certainly an aristocrat and the easiest perennial brassica in cold climates (along wtih even hardier Crambe cordifolia) as it is hardier than perennial kales as it resprouts from the roots every spring and can easily be covered by a mulch of leaves or suchlike in colder climates. I do this every autumn just in case we have a very cold winter (I have experienced plants to resprout from deep roots when the surface roots have been killed in winter). I would normally take off the leaf mulch early April, but this winter it’s been so mild I removed it a few days ago and the plant had already put out delicious sprouts…I’ve been snacking on them! My oldest sea kale is approaching 40 years old, but hasn’t appeared yet (oldies sleep longer I guess!). Much more about Sea Kale in my book Around the World in 80 plants or by searching here: https://www.edimentals.com/blog/?s=sea+kale
They are also beautiful. The pictures show the cultivar Lily White which is only about 8 years old.
My youngest seakale Crambe maritima “Lily White” which isn’t that young longer (17 years old), is in full flower a couple of weeks earlier than my other plants and its looking better than ever this year! In the winter, I dug a trench along the “ex-driveway”, now path to the house, to stop tree roots invading and drying up the shallow soiled beds in this part of the garden.
Since I first blogged about an invasion of diamondback moths (kålmøll) two days ago, reports have been coming in across Scandinavia of the enormity of this invasion, even reaching the farthest north parts of the Norwegian mainland in Finnmark, the arctic city of Tromsø and Northern Sweden. In some places, it’s been too cold to start planting out vegetables!
There were more than a thousand moths in my garden yesterday and they were observed swarming over my perennial kales (Brassica oleracea), sea kale (Crambe maritima) and common wintercress (Barbarea vulgaris), none of which are likely to be severely affected.
There’s been a major arrival of diamondback moths (kålmøll) here since yesterday and there are hundreds of this major Brassica pest in the garden today! I am thankfully only growing perennial kales (Brassica oleracea) and resistent sea kale (Crambe maritima) this year, both of which are already close to maximum yield and unlikely to be severely affected by the moth. This also means I don’t need to use any form of protection (horticultural fleece / fiberduk) which is probably a major source of agricultural microplastics. Problem solved!
I was blown away by the edible and medicinal gardens at the Janas Ecovillage (Ecoaldeia de Janas) during my stay there. Part of my course there was a tour of the gardens and when I enthused about the Portuguese perennial kale growing well in the gardens somebody quipped “Must be the holy grail of veggies!”. Well, not far from it, I’d tried to find it on previous work trip to Portugal having read João Silva Dias’ paper about it (see the last slide for the reference). I had contacted Dias (at the Technical University of Lisbon) to ask if he would share cuttings, but sadly he wasn’t willing. Imagine my surprise then seeing a woody plant that resembled the pictures in his paper. It was confirmed to be called Couve de Estaca (which I think means cabbage propagated by cuttings) in the ecovillage garden. The oldest plant was about 4 years and there was a newer two year old bed planted closely from cuttings! It didn’t flower!
So, here are a few pictures of the holy grail kale :)
A flock of 10 bramblings (bjørkefink) and 3 chaffinches in the garden this morning. They were also taking kale (Brassica oleracea) seed (second film). I hadn’t noticed this before! A plan then to grow kale seed for the finches in future..
After my visit to Tim Phillips’ walled garden vineyard (see http://www.edimentals.com/blog/?p=10678), I was very happy that Susan Campbell found time in a busy schedule to meet and she drove me to her and husband Mike Kleyn’s home and garden on the Solent… sadly, Mike was travelling on the other side of the world visiting family… :(
Susan is the co-founder, in 2001, of the Walled Kitchen Garden Network and began researching the history of walled kitchen gardens in 1981 (the same year that I moved to Norway, so I know it’s an awful long time!). She has personally visited and photographed over 600 walled kitchen gardens in the UK and abroad, making her a foremost authority on the subject. I met her as she had come across my book and on the strength of it invited me over from Norway to give a couple of talks at the Walled Kitchen Garden Network Forum at Croome (see http://www.edimentals.com/blog/?page_id=2554). You can read more about this network here: http://www.walledgardens.net
However, the main reason for my visit was to see first hand Susan’s sea kale yard, the only operation I’m aware of that delivers seakale commercially in the UK, despite sea kale being for me the most English of all vegetables and for some the King of vegetables! See also my blog post about visiting the Curtis Museum in Alton, coming soon!
I found this beauty in my cellar at the weekend…it wasn’t variegated during the summer, but in the cool low light conditions of my cellar this is the result (from seed of a perennial kale grex that I received from Chris Homanics).
The best living displays of the diversity of Brassicas I’ve seen was in the Munich Botanical Garden in Germany in November 2015, including an apparently perennial kale I hadn’t seen before… Braunkohl “Rote Palme”. Please let me know if you know more about this kale, also if you know of a source of seed /cuttings.
