morning glories - super easy, grow pretty much everywhere
hawiian baby woodrose - will only go to seed in a (semi)tropical climate probably not very useful for your purposes
phalaris grass - will also grow pretty much anywhere
wild dagga - I believe should grow well in a season
san pedro cactus - is always a good call
salvia divinorum - makes a wonderful houseplant
p. cubensis - also always a good call
fly agriaric mushrooms - are almost impossible to cultivate because they grow in
a symbiotic relationship with certain types of pine trees
damiana - I believe should be pretty easy to grow in a season
mullein - also should grow pretty easily in a season
blue lotus & white lotus - I believe need to grow in a pond of some sort
mimosa hostilis - can be grown in pots indoors but will take up quite a bit of space as it gets big, would really prefer to grow outdoors in a (semi)tropical climate
caapi or other MAOI containing plants - caapi is probably your best bet, makes a lovely houseplant
Hope that helps a bit
