I started buying some of the more unusual seeds because I got interested in flowers, vegetables, etc. that are unusual for where I live.

For now I have following seeds:
Bolivian Rainbow Pepper*
Ornamental chili pepper*
Black cobra pepper
Chocolate habanero pepper
Trinidad Morgua Scorpio pepper

Light blue and purple maple-
Japanese white pine-
Coffee arabica-
Aloe vera-
Desert rose*
Sensitive fern (Mimosa pudica)*
Wood apple-
Red apple (inside too)-
Dragon blood tree-
Passion fruit-
White strawberry
Red Hot Poker Torch
Bergamot Yellow Gold Buddha Hand*
Panax Ginseng
Ginkgo Biloba
Jasmine Gardenia
Chocolate Cosmos
Mountain Rose Aeonium Greenovia-
Pachira Macrocarpa
Cereus peruvianus monstrosus
Kalanchoe Tubiflora
Bird Of Paradise-
Various Carnivorous flowers

The ones with * next to them are already growing without too much special treatment. The ones with - next to them I am still waiting to see if anything happens.

I'd welcome any and all advice. I just can't really mix anything with sand or anything similar, since I'm not sure if I can find it anywhere, so everything is pretty much in soil/humus that you can get from flower shops.

Most seeds should not be frozen. Those that need stratification should not normally go below 0C/32F degrees in a refrigerator. In general, plants that originate in warm winter areas do not need to be chilled (because they would not naturally be where they are native) and that looks like most on your list.

You should be able to find germination information for each of these individually on the internet. There are also books available on propagation that include listings of specific requirements by plant.

There is also a special Seeds Form here on this site:

Thank you.

Any idea if some of these won't grow in a European climate and I shouldn't bother hoping for them to grow?
