My Drosera weren't happy, ive lost 2 this year my other one i kept inside cause its still young, definitely won't be putting any of my Drosera outside next year was a hard lesson =P

It`s mean that is wrong information that Droseras not go dormancy in United Kingdom :-) .

Drosera capensis and Drosera aliciae are from South Africa, not from the UK. Drosera spatulata has many forms, but most of them are from tropical Asia to my knowledge. All of them grow all year-around in their natural habitats, so they don't have a cold dormancy.

What happened to your plants, is that they died back because of the cold weather. If you had kept them for example in a terrarium (inside), they would not have died back like that. They would've kept growing.

But instead of totally dying, the D. capensis in the photo returned from it's roots, because it didn't freeze completely. So I can assume the weather didn't go under 0 celsius degrees. You can now only hope that the other plants have also survived the weather, and will return from roots. You should bring them inside or put them in a warm greenhouse to ensure that.

Hello, i know from with places are that plants, i just say that they go to dormancy in UK :) . You see, my plants are inside on windows sil, and room temperature always between 18-20 C . It`s cannot be for cold weather, i think is because winter time day light / day time shorter thats way plants go to dormancy . Are i`am right?

Did you forget to water them? Those plants don't have dormancy, they won't do something like that unless something has gone wrong.

Sebulon is right a D.Capensis shouldn't go in dormancy. I grow mine also in the window sill, it growed slower because there are less light hours, but it didn't go in dormancy at all.

Very strange    , i always put watter . I don`t know what happened, but all my droseras are in sleep now event pygmy Lake Badgerup. Strange very strange.

Some drosera go into dormancy, some don't.  It depends.  Temperate sundews like rotundifolia go into dormancy in the winter.  Capensis and capillaris are tropicals and don't have a dormancy period.

But my Drosera Capensis plants died in winter...go to dormancy, but now grow back :)

While the term "tropical" is used to describe sundews like capensis, I think this tends to be a bit misleading. It actually gets pretty chilly at the Cape in South Africa in the winter - close to, if not under, freezing point - and as far as I know the plants do go through a die-back in the wild during the coldest period. A lot of so-called tropicals grow in areas that have more temperate climates, or at the very least have cooler nights.

Having said that, if your capensis died back in the winter months and you were keeping it indoors at 18 - 20 C and well-watered, then as you say day-length must have been the deciding factor. I don't know if that's terribly common though ...

Here in Taipei the winters rarely get down below 10 C and daylight hours aren't quite as markedly reduced as in the UK, and this is quite a happy time for my D. capensis. The time they really hate is the summer, when high temperatures - day and night - result in extreme die-back, and sometimes outright death.
