They should be able to withstand a good amount of water in the summer outdoors but as oetzi13 said they are sensitive to too much sunlight  after a long winter indoors so best to adjust them slowly in the spring.  Where you're at I would say that planting outdoors is not an option at all...highly unlikely they can handle a central Canadian winter.  I'm jealous of those that are able to plant these beauties outdoors where they can thrive all year!
