D. intermedia.....

[Pananep]

Hello everyone.... A couple of months ago I purchased a package of mixed Drosera seeds. They were sowed and have now reached a size at which they can be identified. Apparently the package I received was not of mixed varieties but only contained what I believe to be D. intemedia. I will try to provide a picture later on today to confirm my ID on this plant with anyone here.
Anyways, I know that the North American and European varieties require a cold winter in which they form hybernacula while varieties from Cuba and South America do not. I really wanted to know if there was any way that I could tell or differentiate between these varieties. This information is a must have in order for me to know how to treat these plants and what to provide them with. If they are of the N. American or European varieties I am goign to have to firgure out a way to provide them with a dormancy. Would a fridge be suitable as it is for Sarracenia and VFT? I am hoping that they are either the Cuba of S. American varieties as these would be suitable to grow year round here in Panama.
Any information on this topic would be greatly appreciated. Once again, I will try and post the pic later today. Thanks! Later!
