Philippa is right - you are starting at the wrong end. You need to do some research about local conditions and the plants that grow well where you are. These will be easy to buy and maintain. They may well be seasonal because most places have seasons.
If you want to grow plants that require different conditions then you should work out how to provide these BEFORE buying the plants. They will not survive inside your house for long unless you can give them the correct amount of light, warmth and humidity. A greenhouse can be heated with electric heaters but you can buy oil or paraffin heaters if there is no power.
Growing plants is a great hobby but you will waste an awful lot of money if you don't understand the plants' needs. They won't thrive just because you want them to and you have paid for them! Learn, plan and work out the basics, start small and develop as you learn.
