question about sundew dormancy

by Earthy » Sat Sep 19, 2015 11:13 pm

so, I was wondering if any of my sundews will need a dormancy? I have D. Binata and a D. Alicea for sure. not sure what the other 2 are lol...I posted pics of them in the Sundew part of the forum...any advice?

My binatas will typically go dormant during winter, they are tuberous (i think thats the right word), well either way, they will go dormant, and when they do, you can dig the roots up, and split them into new cuttings, not sure about alicea though.

edit: some (or most?) drosera don't go dormant at all.. i think it's the tropical ones that stay active year round.

D. binata depends on the form. Some go dormant, some don't, and some only if conditions are bad. D. alicae does not require dormancy.

Drosera binata aren't tuberous, though they have thick, fleshy roots. Most types of D. binata respond to changing day lengths and will go dormant over winter. No need to chill it.

D. aliciae does not grow dormant and will grow year round.

So, I should just put them in the south window and let them go dormant if they want to?

Sounds good. Give them as much sunlight as possible and let it do what comes naturally.

The drosera binata is temperate, so it requires dormancy, the aliciae is tropical, no dormancy required, and if you live in an area with cold winters, then you can just put the binata outside during the winter and let the plant get the natural dormancy.

If they freeze, that's ok, last year, where I live (in Charlotte, North Carolina) it was snowing on my bog container full of vfts and sundews and sarrs, it was extreme weather and the plants were frozen, and when I touched the soil, it was frozen solid, but surprisingly, in spring, it came back :D

Not sure if all D. binata varieties could survive being frozen. Some come from the mountains or south, so it does snow every year but a lot of the 'larger' populations are from coastal subtropical australia. It never snows at these regions.

Yeah, in my bog, I don't have binatas in it, only have intermedias and some sarrs and vfts, I don't know about binata. I also have a Drosera X Martson's Dragon, which is a cross between 2 binata varieties, I think it was d. Dichotoma and d. Binata multifida extrema, and I heard people say that it doesn't need dormancy, last year, I didn't give it dormancy and it's looking fine, I guess that hybrid just doesn't need dormancy.

Does drosera spatulata (I think it's spelled like that, I'm sorry lol) go into dormancy? I think I read somewhere that they don't, but I'm not sure..

Spatulatas are tropical, meaning they don't need dormancy. Most rosetted sundews are tropical, examples are d. burmanii, d. spatulata, d. slackii. Pretty much, sundews that have spoon-shaped leaves are rosetted and tropical. But some exclusions are d. intermedia and d. capillaris
