Here is the 4th edition of our Seed Ambassadors Project Seed Saving Guide.

Please download our seed saving guide and share it widely! “A Guide to Seed Saving, Seed Stewardship & Seed Sovereignty”

Seed Saving Zine 4 hand out (3.8 MB PDF) This handout formatted version is your best choice for printing and reading if you do not have one of those fancy zine staplers.

Seed Saving Zine 4 duplex (3.5 MB PDF) This zine formatted version is for printing in a duplex printer and folding into a Zine. That is why the pages seem to be in a weird order. If your printer does not have duplex ability you can print it one page at a time, flipping each page over to print the back side.

All about Russian & Siberian Kale

Originally arranged 8/06 by Andrew Still and updated 7/07 with small update 8/14.

Introduction

Brassica napus

It is hard to convince everybody of this fact, but kale is the swellest of vegetables and Brassica napus is the best of the best. The Russo-Siberian Kales mostly have come out of Northern Europe and Northern Asia, though in the past century they have been shuffled back and forth across the globe like many of our cultivated plant species. Red Russian and Siberian are the two most well known varieties in the United States, however many others have been developed from these lines.

These kales are typically more tender and have a milder flavor than the European “oleracea” kales and are therefore the young leaves are better for salad use. They are always superb as a cooked vegetable when the leaves have grown to full size. Most Varieties are great for used for their springtime sprouts (similar to broccoli raab), although some varieties are specially bred for that use.

Napus kales are super hardy winter survivalists. They are hardy to at least 10°F once established and some sources claim them to be hardy to -10°F and maybe -20°F. Survival at these extra low temperatures may require a good mulch and/or snow cover. There are many factors known and unknown that can effect winter hardiness and there can be no real guarantee for how cold a crop can go. Wind can be an important factor in killing plants and a pattern of freeze thaw freeze thaw can also be detrimental. They Perform best in cool weather but many varieties of napus kales tolerate hot weather. It is widely known that the flavor of Russo-Siberian kale sweetens dramatically after first frost. It can be grown anywhere in the US and even in Alaska.

Being variable in its forms, Brassica napus is divided into three groups or subspecies. The Rutabaga (Swedes in England) is ssp. napobrassica or rapifera and are grown for grown for their swollen stems/roots that resemble turnips (B. rapa). Russo-Siberian Kales and Hanover Salad are ssp. pabularis or pabularia and are grown for their leaves that may resemble those of the European kales (B. oleracea). Winter rape and canola, colza in India, are grown for their edible leaves, livestock forage, or for the oil rich seed. All have large, flat leaves 12-20 in (30.5-50.8 cm) long and 8-15 in (20.3-38.1 cm) wide, stand 2-4 ft (0.6-1.2 m) when mature, have yellow, cross-shaped flowers with four petals and the small seed develops in sickle shaped pods.

Presently, the species Brassica napus is thought to have originated from a chance hybridization between Brassica rapa and Brassica oleracea. This cross probably happened in European gardens during the Middle Ages. The rutabaga, kale and rape may have all originated from separate chance hybridization between the diverse forms of B. napa and B. oleracea. For example, napus kale could have been derived from B. oleracea ssp. acephala (kale/collard) crossing with the B. napa ssp. chinensis (Asian mustard). The rutabaga could have been derived from B. oleracea ssp. acephala (kale/collard) crossing with the B. napa ssp. rapifera (turnip).

The red Russian type of kales may have a different story. Tim Peters of Peters Seed and Research did an experiment to retrace the evolution of B. napus. He first crossed a Chinese cabbage (B. rapa) with a European kale (B. oleracea). He did these crosses with a bud pollination technique, which he says “lets the two species have more time to get to know each other”. After the first cross the result was a beautiful Siberian kale  (B. napus). then he crossed in black mustard (B. nigra). This resulted in the red Russian type (B. napus?) with its distinct color and leaf shapes. So some of the B. napus species are two way mix-ups and some are three way mix-ups. How wonderful! This throws a wrench of doubt into the machine of the probable genealogy of plants, such are the ways of science.

Plan B… More Hamburg, then Grain

Our plans for Poland on the 9th of December fell through, and so we found ourselves in Hamburg with lots of options but no plans. We did what we could to pursue new seed-related contacts, even recruiting the help of Christina and Juan, but we found last-minute arrangements around the holidays to be somewhat difficult in Germany.

We wound up staying in Hamburg until our December 17th flight to Lithuania, mostly exploring various parts of the city and lying low.

One of the contacts Christina pursued for us worked out, and so we spent a delightful afternoon with Karl-Josef Muller, the head of the Association for Biodynamic Plant Breeders, and his fellow cereal breeder Martin Timmermann. Karl Joseph has been breeding for high quality grains in low fertility, low-input organic systems since 1986, and has developed and registered a variety of “naked” barley, Lawina, on the EU’s common catalogue. Take a Look at their website “Cereal Breeding Research Darzau” it contains a lot of great information.

We first checked out of some of their “nursery” plots and grow-out fields of fall-planted rye, spelt, einkorn, and barley on neighboring organic and biodynamic farms. Then we returned to the research center to see some of the specialized equipment (including custom tractor and special de-hulling machine), and then retired to their offices for coffee and a long discussion of the methods and whys and wherefores of organic grain breeding.

Karl-Josef told us, “Our aim is to develop new varieties, but it does not end there. It is also to develop new ideas for new varieties and to research and tell others (even the conventional breeders) what we have learned. Because if the idea is developed, sometimes that is enough for now. The market/interest (in organically developed seeds) is very small, but it is not our job to improve this. What is important is to develop new criteria for farming, organic farming, human being, these ideas.”

It was a wonderful visit, and we left with a few new varieties of grains (Lawina naked barley and a light grain rye), and shared with Martin some of the perennial wheat that we had brought. We also left with our heads full of new ideas and information.
