Oregano and Marjoram: What's the Difference? Plus Grow Leeks

 SPICE IT UP

Oregano vs Marjoram: What's the Difference?

How well do you know your herbs?
You may have a herb garden so are pretty much used to telling the difference between one herb and another, but there are some herbs that look really similar.
  • Have you ever asked one of your household to go and get something like say sage leaves from your garden, and they came back with some catmint or something else?
  • Or perhaps you’ve planted one of these similar looking herbs and have forgotten which is which?
Can you tell which of the herbs pictured below is oregano and which is marjoram?

It’s time to have a closer look and write up a label.
Marjoram and oregano are very close relatives.
Even more confusing because the latin name for marjoram genus is Origanum

Scientific name: Oregano majorana
Common name: marjoram
Family: Lamiaceae or mint family
Scientific name: Oreganum vulgare
Common name: oregano
Family: Lamiaceae or mint family

How to tell the difference at a glance

  • Marjoram leaf will generally be a little bit smaller and rounder whereas the oregano leaf tends to be elongated and slightly larger..
  • Oregano leaf will be slightly fuzzy looking in appearance.
  • Oregano grows vigorously throughout the year and is considered a tought herb.
  • Marjoram is likely to die off in colder weather.
  • Marjoram has a milder flavour than oregano.
  • Oregano has a slightly peppery note to it.
Varieties of marjoram
Pot marjoram: Origanum onites
Winter  or wild marjoram: Origanum heraclesticum

Varieties of oregano.
Greek oregano: Origanum vulgare hirtum
Mexican oregano: Poliomentha longiflora 
Poliomentha is not to be confused with  another herb also called Mexican oregano and a member of the verbena family, namely, Lippia graveolens.
  • As always, common names will trap the unwary.
Let’s find out a bit more about these herbs and how they can be used in cooking.

VEGETABLE HEROES

Leeks: Allium ampeloprasum var. Porrum
There’s nothing like a good long history that some vegetables seem to have and the Leek is no exception.
Leeks are supposed to be native to Central Asia, and have been cultivated there and in Europe for thousands of years.
  • Did you know that Leeks were prized by the ancient Greeks and Romans because of their supposed beneficial effect upon the throat.
  • The Greek philosopher Aristotle thought that the clear voice of the partridge was due to a diet of leeks, while the Roman emperor Nero supposedly ate leeks everyday to make his voice stronger.
  • Another interesting fact that you might not know is that the leek became a Welsh emblem in 1536, and is still the national emblem of Wales. Daffodil is the National flower.
  • Have you ever wondered why Welsh are such great singers?Perhaps because they eat a lot of leeks, think Tom Jones.
Leeks, known scientifically as Allium ampeloprasum var. Porrum, are related to garlic, onions, shallots, and scallions.
  • Onions, celery, and carrots are very good companion plants for the leek.
Leeks, are a cool season crop and best of all they’re easy to grow.
  • You can grow leeks in hot summers, but you won’t get the same quality result as you will in a cool summer environment.
I know I’ve tried and they were a thinner weaker version of the winter leek.
Leeks are usually grown from seed and are generally started off in punnets first then transplanted.
When to Sow
Sow the seeds of Leeks from Spring until the end of Autumn in cool temperate climates, and late summer and autumn in warm and tropical zones, and in arid districts, seeds must be sown in February/early March and then you can transplant them in April and May. 
I sowed some seed a several weeks ago and have already transplanted them into the veggie bed because they were a couple of inches-about 10cm high and were the thickness of a pencil.
TIP: By the way, the seeds germinated fine from an out of date packet.
Leeks will overwinter in cool temperate areas of Australia if properly mulched, but will generally not survive periods of extreme cold.
In case you don’t know what a leek is.
Leeks look like large fat spring onions, but have a very small bulb and a long white cylindrical stalk of layers of white then green, tightly wrapped, flat leaves.
  • It goes without saying that good soil is the key to growing leeks.
  • Leeks need nutrient rich, well-drained soil with a pH between 6.0 and 7.0.
  • They’ll do well in almost any garden soil as long as it is well aerated and deep, about a spade’s depth is good. Using some kind of dibble tool or stick to make a hole that's just deep enough to leave only the top inch of the seedling exposed.
  • Set the leek seedling into the hole and fill it loosely with soil.
  • Space the leeks 10cm or a large hand span" apart, in rows at least 25cm  or from your wrist to your elbow apart. Find something practical like that to do you estimates.
Some people think that when growing Leeks the aim is to blanch the stems while the plants are maturing.
To save your back if you want to blanch the stems, rather than digging a trench, just use mulch.
When they’re 4 weeks old in the veggie bed, use a thick mulch of sugar cane or something like that.
In another 4 weeks or when they reach about 24cm, do the same again, or you can use shredded newspaper.
The leeks will still grow as well if you don’t do any of this.
Some gardeners cut off the top portion of the leaves, about halfway up the plant, as the leeks are maturing.
This is supposed to bring on stalk growth, giving you a larger leek for the dinner table.
  • To be honest you can do all this, but if you don’t the leeks are just as tasty.
Make sure the plants get at least a couple of cm’s of water a week; otherwise the stems will be tough to eat.
Mulch to conserve moisture, and side-dress with manure tea once a month.
Begin harvesting leeks as soon as they're big enough to use.
Young, tender ones are good raw; once they reach the width of a paper roll, they're better cooked.
They usually take 16-18 weeks--4 ½ months.
Quite a long time so explains why they are so expensive at the greengrocer, market or wherever you buy them.
To prepare Leeks cut them very thinly and sautee’ just as you would other members of the onion family.
 Like their allium cousins, onions and garlic, let leeks sit for at least 5 minutes after cutting and before cooking to enhance their health-promoting qualities.
Why are they good for you?
Good source of dietary fibre also a top source of vitamin C
Leeks have a high concentration of the B vitamin folate
Leeks give you small amounts of other minerals and vitamins.
Like onions, they also have some sulphur compounds that scientists believe reduce your risk of some health problems.
Leeks are believed to be good for the throat.
Leeks are low in calories and fat-free. 100g of leek has just 125kJ.
AND THAT WAS YOUR VEGETABLE HERO FOR TODAY
