Are germination requirements different for main groups of Droseras (other than temperate with cold stratification and tuberous with smoking)? The growing requirements that really matter? What kinds of droseras can be grouped and grown together? Thanks ;D

Most drosera follow the same germination rules as others in their category (temperate, tropical, tuberous, pygmy). Usually if you plant from the same group you can grow them together. THere are some exceptions so be sure to check first. The main growing requirements are (in what I think is order of importance): Light/Humidity, medium, water, stratification, age of seed
Hope this helps, Zac

There are differences for sure in light, humidity, watering and temperature requirements. Some seem quite picky, some don't. Some have winter dormancies, some summer dormancies, some go dormant whenever it gets dry. Drosera are a wide ranging group of plants (genus? not up on my taxonomy) and that wide range yields differing requirements.
I don't use artificial lights at all.
I find native (rotundifolia, intermedia) ones grow best outside. There with enough sunlight they turn red while inside they grown green. They like lots of water, standing in it, with a fair amount of humidity but don't need a huge amount.
Adelae seems fairly easy to grow, and doesn't mind cold or warm temperatures. It likes a lot of water but doesn't shrivel up if it gets a little dry. It seems to flower all year round. Likes lots of moisture and lots of light.
Multifada extreme needs lots of water and moisture to grow well. Without that, it goes dormant but bounces right back if you water it again.
Slackii has fairly strict temperature and humidity requirements or else it won't grow well. It needs lots of light or it will grow scraggely but if you make it too hot it doesn't do well. It needs moderate temperatures, high light and humidity to grow properly.
Prolifera needs lots of humidity, not so much light and definitely not high temperatures.
I can grow Slackii and Prolifera together, Adelae and Multifada together and native ones together so that's three groups at least and there are still many different species to consider.

I find trying to group plants together based on others experiences to be of little use. personnally I grow everything together and get good results, that's my experience, but others differ. I may keep some plants in deeper saucers while others are free to stay in big square margarine tubs. for example, I have (all in 2" pots) in one square tub, p. sethos, varrious sarracenia seedlings, various pygmies, and d. filiformis ssp. filiformis. All around that are my flytraps. On the other side are neps, these are all on an open growstand. Works for me, and that's all I can offer. Sib

Thank you, very informative! Just curious: what zone is Guelph to winterize some droseras outdoors (and which droseras else particularly)? I'm in 6a USDA.

Pay attention to location when recieving stock, but for drosera, rotundifolia, linearis, angelica, and various hybrids of these can all be left out. with some protection and some experimentation, you may find others like binata and filiforms that can make it. Sib

filiformis ssp filiformis can definitely make it through the winter under mulch, if you like I'll send some of those to try for you too, they just need fridge strat- trying VFTs this year, and S.flava did pretty darn good over last winter....

Guelph is 5A but rotundifolia and intermedia both live here and even in 4B.

D. intermedia species is very widespread in America, it lives in a variety of climates. They are present up in northern Canada, and also in tropical Cuba. I would not say that the cuban form would live in our cold winters. The case is also similar for D. rotundifolia.

I tend to group plants according to whether they are tropical, warm temperate or temperate. For instance, my pigmy sundews are in the attic, where they see coldish temps in winter and very hot temps in the summer. I keep binata, intermedia, rotundifolia, and filiformis in minbogs and they are outside for 3/4 of the year and the attic in the winter. I have D. paradoxa, adelae, spatulata, dielsiana, aliciae, and capensis in the bathroom window all year round.
