These days everyone takes potatoes for granted. In many parts of the world, especially Europe, potatoes are very popular and regularly feature prominently in meals. The potato is the forth most cultivated crop after rice, wheat and corn. The potato was introduced to Europe, from it’s native Peru in the Andes mountains of South America around 1700, and quickly became one of the most important crops in the world.

Just like the potato, there is suddenly a realization that many plants commonly grown in this region have the potential for cultivation as commercial crops elsewhere in the world. Listed below are several I plan to grow in my garden this year.

I’d like to thank Frank van Keirsbilck, a Belgian member of the Seed Savers Exchange, who not only gave me some yacón tubers for my garden this year but also agreed to let me use his pictures for this post. All the pictures you see below are his and of plants he is growing. He said he may put together his own blog, so hopefully we will see more from his garden.

Mashua (also called Añu)

Mashua

This plant is a member of the nasturtium, and has very peppery tasting roots. It is commonly cooked into stews, where it loses it’s harsh flavor and becomes sweet. I grew this last year in a container, but got a poor crop. I will try it again this year in the garden. Lieven, who gave me this tuber, reported a very substantial crop last year.

Ulluco

Ulluco

Ulluco

This plant is considered to be one of the most promising for commercial production. In many parts of South American these colorful tubers are sold in markets and stores. The pictures above are of solid colored tubers, but some varieties have stripes or splotches of different colors. Most of the tubers I’ve seen have been very brightly colored.

These are supposed to taste very good just eaten raw as a snack or part of a meal. They can also be cooked and eaten similar to a potato. The leaves can be eaten like spinach.

Viruses are apparently a major issue for commercial cultivation of this crop. Efforts are under way to try to produce some virus free planting stock which is expected to be significantly more productive than what is now available.

One of the major issues concerning growing attempts in northern Europe now is no one really knows the best way to cultivate this plant in the local climate. Except for being very vulnerable to frost, they are apparently grown similar to a potato. They are day length sensitive, and produce most of their tubers in October or November when there is often frost in our area.

Growing this plant promises to be a challenge.

At the time of this post, Real Seeds in the UK were offering ulluco tubers as an experimental plant for people wishing to give it a try. Apparently Frank, the person who let me use these pictures was one of the sources where Real Seeds got their tubers from.

I have found some references on the Internet suggesting planting time is important for this crop. A study in New Zealand suggested planting closer to the summer solstice was preferred to an early planting. I also came across a UK grower who suggested starting it indoors under lights, then planting it out later.

I will divide my tubers in three groups. The first has already been planted out. The second is potted and growing indoors under a light. The third is still in storage. I will plant out these latter groups in several weeks.

Oca

Oca

Oca

Oca can be boiled, baked, fried, mixed fresh with salads, or pickled in vinegar. Cultivation is reported to be very easy, but viruses are also an issue in this crop which could impact commercial yields. According to the book mentioned above, the commercial importance of this crop is second only to the potato in it’s native Andes.

I have some Oca tubers both from my friend Lieven as well as from Real Seeds in the UK.

Yacón

You can see some pictures of this plant on Søren’s blog.

This plant is related to the dahlia, and produces large tubers which store well. These tubers can be cooked, but most people say they are best eaten raw. They are very sweet, and are very high in inulin similar to Jerusalem Artichokes. This gives them a nice sweet flavor, but can also cause flatulence in some people.

Inulin can also be converted easily to ethanol, making this plant a possibly interesting source for biofuel for use in cars.

Plants normally produce heavy yields, often 10-20 Kg per plant. Many people who grow lost Incan crops report this to be one of the most rewarding for the home garden.

Tarwi

This plant is a variety of Lupin, and is supposed to be one of the most attractive lost Incan crops.

Similar in nutritional composition as soy beans, this plant provides a good source of protein. It can be prepared in many of the same ways as soy beans and also just eaten by itself as a snack, especially when the seeds are in their fresh mature state. The seeds contain bitter alkaloids making them initially inedible, but these alkaloids are water soluble and can be removed with several days of soaking and rinsing with water.

This plant is nitrogen fixing, and so is useful as a green manure crop.

I have ordered some Tarwi from a Seed Savers Exchange member living in Peru, which I expect to arrive in time for planting this year.

Quinoa

I have been eating and enjoying quinoa for years now. Also called Incan rice, it is cooked exactly the same as normal rice and is an excellent substitute in many dishes.

When you purchase commercial quinoa, it is usually treated in order to remove it’s bitter alkaloids. When you grow it your own garden, you need to do this yourself by soaking it in water overnight and thoroughly rinsing before using.

I have purchased some Rainbow quinoa from Real Seeds for planting this year.

Dwindling Resources

Mike on Planb just made a really thought provoking and well written post on the problems South Africa is having with their power grid, and as a result everything that depends on electricity. This has certainly been in the news here, but the magnitude of the problem is much more clear in Mike’s post.

It’s worth mentioning Mike has been anticipating this for years, and has designed his house and farm so that as much as possible will keep functioning the event of a power outage.

The Internet connection is another story…

In many ways we should be looking at South Africa as an indication of the future we will all likely see. Shortages of food, water and energy are all looming on the horizon. It’s what’s being called the end of ‘The Goldilocks Era’. It can only help to be prepared the best we can, and of course growing a portion of our own food or supporting local agriculture is an important part of that.

Geert Wilders New Dutch Film

Just a brief off-topic post to allow me to express how thoroughly disgusted I am at the release of such a racist film in this country.

I think I am joined by the vast majority of Dutch people in my feelings, and probably most people elsewhere in the world too.  I would like to offer my personal apology to any Muslim or other person offended by this film.  A film like this doesn’t have any place in a civilized society.

A country that directly elects it’s members of parliament with a popular vote can inevitably see someone get elected from the political fringes with only a small number of votes, and that’s what’s happened here.  The only way a person like this has a chance of advancing themselves politically is by drawing attention to themselves in this kind of way.

The best way to deal with a person like this is publicly state your polite and firm disagreement, but otherwise ignore him.  I would urge everyone not to give this person any unnecessary attention.

Illegal Seeds

Association Kokopelli, probably the largest seed saving organization in Europe has been fined €35,000 for selling illegal seeds.

In this case illegal means traditional and rare seed varieties, which were not on the official EU-approved list.  These are deemed illegal to sell on the grounds that it gives the seller an “unfair trading advantage”.

The size of this fine has the potential to put Kokopelli out of business.

Hardening Off — Don’t Forget!

This is a reminder I’ve made over the last couple of years around this time.

If you are new to gardening, and have started plants indoors under lights, don’t forget to harden them off before moving them outside or they will probably die!

Hardening off simply means to introduce them slowly to the outdoor weather, usually over the course of about a week. Otherwise the shock of moving from a sheltered room and grow lights to outdoors will just be too much for the plants.

I harden off my plants according to the following schedule of outdoor time:

Day 1: 15 minutes

Day 2: 30 minutes

Day 3: 1 hour

Day 4: 2 hours

Day 5: 4 hours

Day 6: 8 hours

Day 7: Plants are ready to be left outdoors

These times are approximate! Don’t drive yourself crazy over them.

While hardening the plants, you should also introduce them slowly to full sun.

Many people have other ways or systems of hardening plants. For example some people make use of a coldframe or greenhouse and slowly let in more outside air. Other people have different times for different days. Some people make use of plastic milk jugs. As long as it takes at least a week, and you are introducing your plants gradually to the outdoors, it should work fine.

A lot of people ask me questions like what about moving plants from a polytunnel or some other in between situation? I don’t really know. I suggest, if you have a plant you can afford to lose if necessay, set it out for an hour while carefully watching it for signs of stress. Look at the plant again the following day. If there are no signs of stress, than it is probably okay to just set the plants outdoors. To be certain, it’s still better to harden them first.

Hardening off plants is a risky time! Many gardeners lose plants while trying to harden them. Watch your plants closely, and if any start showing signs of stress, move them back inside for a few days and try hardening them again from the beginning.

If you move your plants back indoors after hardening, you will need to reharden them!
