Turnip Brassica rapa ssp. rapa f. majalis


This photo is called "turnips"

Turnip seems to be a dream crop for the indoor gardener, it's fast growing and both root and leaves can be eaten. It prefers light soils, but I suspect it can grow almost everywhere. It's a coldclimate crop, which makes it most popular on the nortern parts of the globe.

Since I've found cooking tips both for root bulbs and leaves I conclude that they both are tasty. The plant contains a lot of vitamin C, as well as B2, B1, B6, folat and niacine. The leaves are the most concentrated and contains a comparable large amount of protein (to be a plant of that kind, that is).

The downside is that turnip contains oxalat, which - if you eat a lot of it - crystallize in the body and causes different kinds of health problems. What concerns me more is that turnip contains goitrogens that surpress the thyroid function. Any person with diagnosed but untreated thyroid problems should avoid turnip. Since many of our old cultivated crops do contain oxalats (spinach and rubarb) or goitrogens (most cabbages) I suspect that these 'back sides' can be balanced by a varied diet and by drinking an healthy amount of water (1-2 litres or 1/3 - 2/3 gallon).

A side note on thyroid problems; If you are suspecting that your thyroid are causing you problems you MUST go to a doctor and get a proper diagnose and treatment. Do never ever EVER think that changing the diet will be enough. Thyroid problems are deadly, and the treatments are often cheap and comfortable. Still, since I have an underfunctioning thyroid myself, I can't help but smile when I read that chocolate and saturated fat stimulates the thyroid. Turnip fried in real butter, mmmmmmm...

The turnip bulb is useful raw, in stews and casseroles and fried as an dish of its own. It gets wooden if it gets to big, so make sure to harvest before it's bigger than 10cm / 4" across. This should not be a big problem for an indoor gardener - I plan to harvest my first roots when they are as big as radishes. The leaves could be eaten fresh as salad, they are said to resemble ruccola in taste. In cooking they are used as - you guessed it - spinach.

Back to the roots

This image is called "just off the turnip truck"

Since my added light projects proceeds in a very slow pace I spend the 'lost' time researching the crops I've bought. You've already seen the result twice, since I've published small articles on common purlsane and ice plant on this blog. Now it's time for the different roots. I like roots. They're nutricious, can be harvested early and stays fresh for a long time. On the other hand I wasn't so sure that I could learn something more about them. The tiger nut are indeed exotic to a swede, but the turnip seems common enough. And the carrot! Is there anything worth to add about the carrot?


I always do my research on the net, using Goooogle and the common swedish name of the plant. As soon as I find a reliable latin name I do a new search on that. This is the best way to find reliable sources. Because the net is littered by plant heads, romantics and wannabe herb gurus, and you need to distinguish between them and the reliables. Read the reliable ones first to have a solid base of knowledge when you go on to read the articles written by plant heads, romantics and wannabe herb gurus. These are often more fun, and may contain some grains of truth.


Indeed, there were quite a lot to say about both turnip and carrot. There's even a museum dedicated solely to this orange root - I'm not at all surprised that there are englishmen and women involved. I'll publish my collected efforts on this blog during the week.


Happy gardening!

Common purlsane Portulaca oleracea ssp.sativus

Well, I bought seeds from common Purslane, but what kind of plant is it?


Apparently it is an old cultivated plant in Sweden and Europe, and it is common to grow it in containers (although the most common way is to plant it in the garden). It looks much like Jade plant (crassula ovata) which is to be found in pots in every place where people show a certain neglect in watering. It's perhaps a good idea not to grow the two plants in the same space. Purlsane is nice enough to grow new branches once you\ve cut it down, as long as you leave stubbs of two inches length. It tastes sour, and contains oxalic acids (like rubarb and spinach), flavonoids and Omega-3 fatty acids.


Before you jump for joy because of the \newfound\ source of Omega-3 I\ll remind you that we are talking plants here. The fat level of plants are in general very low, unless you look at nuts and ceratain fruits. However, I have a feeling that purslane is kind of the plant world shmoo.


You can use it as spinach, but that doesn't say much since spinach is the leaf vegetable world's answer to chicken, ie. if anything isn't possible to use in a very special way it's to be used as spinach. I guess I have to grow it to taste it myself.

Ice plant

Heh. Ice plant proved to be a cool vegetable, although a bit slow to grow. It stays in its juvenile growth for six weeks before turning adult, a stage that can be prolonged for months in a lab (hopefully this is valid for a windowsill too). Then it blooms and start the seed production, and once the seeds are mature the plant dies, roots first. Since the plant collects salt in its leaves the withering plant will contaminate the underlying soil. The seeds can grow in this saltyness, but other herbs and vegetables will not survive, hence competitors for the earth are taken care of. The plant can grow in almost any soil, from well-drained sandy soils (including sand dunes), to loams and clays. Since it absorbs salt and other minerals from the soils it's a candidate for using as 'clean up plant' on polluted grounds.

Ice plant have thick leaves covered with big bladders, it do look frosted. It's hardly a surprise that it taste salt, and sour. You can eat it raw, in woks or treat as spinach (gee, have we heard that one before?), and you can crush the leaves to use them as a soap substitute. Seeds and fruits are edible too. If you collect ice plant leaves, fruits and seeds in the wild, DO CHECK THAT THE GROUND IS CLEAN, since every poison in a poluted ground will be amassed in the plant. Having done that, try this recipe I manage to find.

GREEN ICE BLT SANDWICH
(serves 4)

In origin, this recipe is from the book ”Het Trädgård — odling & recept” (translates as ”Hot garden – cultivation and recipes”)

8-12 slices of bacon
2-3 tomatos, sliced
A giant handfull och ice plant (it says so!)
8 slices of whole grain bread
Gourmet quarg
salt and black pepper
Barbecue blues sauce

Fry the bacon in the oven (200¤C or approx 400¤F) for 7-8 min. Take it out and drain it from fat on domestic paper. Roast the bread in the meantime. Spread the quarg over four of the bread slices, cover with iceplant and add the tomato slices. Spice up the tomatos with salt and pepper, cover them with bacon and pour over the barbecue blue sauce. Add the last bread slices and cut the sandwiches into triangles.

(This is a recipe translatedfrom swedish, you can find the original here.)

Hm, ice plant needs added light, but appart from that it seems to be so hardy you'd have to jump on it several times before it dies. This is a candidate for sowing in that cheap seedling soil I've complained about so much.
