Typical annual vegetable garden plants:

Bean: Like it hot. Can only do well in the cold climate on warm sunny summers. Only Broad Beans seems to do well even in the cold and wet summers. All beans are really good nitrogen fixers.
Beet: A good vegetable in the cold climate, as it is easy to store for a long period of time.
Borage: Provides organic potassium and calcium to the compost. The flowers are edible.
Broccoli: Grow well. Prefer loose, soft soil deep down.
Broccoli
Cabbage: Do well in the cold. Some type of cabbage can even survive the winter, and you can actually harvest fresh green food from a snow covered garden.
Cabbage
Camomile:
Carrot: Are cold hardy, and is fairly good for winterstorage.
Cauliflower: Grow well in cold climate.
Cauliflower
Celery: Good cold climate vegetable, as it can be stored for a long period of time. It is said that it have a hormone simular to insulin, so it is very good for diabetics.
Dill: Very easy and nice herb to grow. Will often sow it self for next years harvest.
Garlic Very healthy and rich in vitamin C.
Leek: An extremly cold hardy plant. Survives well in frost, but donīt like when the temperature goes up again.
Lettuce: Seeds germinate at very low temperatures (about 2°C 35°F). They like alot of nitrogen, which make them taste less bitter.
Onion: Onions are said to be the only vegetable you can live of without eating anything else, because they contain all the basic nutrients the body needs to stay healthy. They are unfortunatly quite sensitive to mildew, which explodes in wet (moist) weather at about 18°C (65°F).
Oxheart Cabbage: Fastgrowing and early cabbage.
Oxheart Cabbage
Parsley: Contains a lot of iron, and is therefore very good for especially women.
Pea: Prefer the chill summers of the temperate climate. Excellent nitrogen fixer.
Potato: One of the best and most popular vegetables in the cold. Mainly because you can store them basicly through the whole winter.
Pumpkin: Grows well in even very weed infested areas. It likes a lot of manure to feed it.
Radish: Fast growing, and fairly cold hardy
Rhubarb:
Scarlet Runner Bean: This very beautiful bean do quite well even in the chill summers.

Snow Peas
Spinach: Healthy and rich in iron.
Sunflower:
Sweet corn: Doesnīt like cold summers, and even in the hot summers they grow slow in the cold climate.
Zucchini: Heavy producer under good (warm and lots of nutrients) conditoins.

Typical greenhouse vegetable plants:

Basil:
Capsicum: Do fine in a greenhouse
Chili: Like capsicums.
Cucumber They like it warm, and when they first start producing, they are really heavy producers. They are very sensitive to mildew, so NEVER water them on their leaves or stems.
Eggplant:
Melon: Melons (and watermelons) are quite hard to grow in a cold climate greenhouse. Their demands for heat is so high, that you need a really good greenhouse, that dont get to cold during the night. They need a long (warm) season to produce a fruit.
Tomato: A very common and delicious plant in the greenhouse. Homegrown tomatoes is just so much better than the ones you buy in the supermarket, mainly because the supermarket ones are picked before they where ripe. They need a stable temperature night and day. If your greenhouse doesnt have a heatstorage or is bad insulated, the leaves on your tomatoes will curl. That is caused by a high temperature during the day, and a low temperature during night. The leaves of the tomate plant grow on the upper side during daytime (by photosynthesis), and on the backside during night (by repiration). If it is to cold during night the bottom side will not grow, and the leave curls. It has no or only little effect to the plant though.

Perrennial garden plants:

Anise:
Asparagus:
Comfrey: The most importent plant for making a fertile tea for your garden. With it's long tap roots, comfrey will collect lost nutrients from deep down in the soil. Leaves can be harvested about 6 times pr year, and added to the compost pile or to a drum filled with water for tea. When making the tea, it is importent to stir in the drum every day, to get oxygene into the mixture. Without oxygen anaerobic processes will take over, and it will start to rot and smell bad. After a week or two, when all the leaves are dissolved, the tea can be watered out in the garden. Add more water to make the tea less strong.
The advantage in using comfrey as fertilizer is, that it contains all the basic nutrients - N, P & K - in a well adjusted relationship.
Since old times comfrey has been used as a medical plant, but it should not be taken internally, because of its content of ... under construction ...
Coriander:
Fennel:
Lavender:
Lemon Balm:
Mint: Nice herb for fx. tea-making. Will spread over a large area, and will then become a weed. Therefore it must be controlled. The roots don't grow deeper than about 30cm, so a border of fx. wood or an old bottomless bucket can be digged into the ground, to prevent the roots from spreading.
Oregano:
Pennyroyal:
Sage:
Strawberry: Propably the best perennial groundcover in the cold temperate climate.
Tarragon:
