I love common house plants, like spider plants and peace lilies. Peace lilies are the best because they wilt if you don't water them for a week, which is a great reminder for me to water the rest of the house plants.
And they are great air cleaning plants according to nasa!
I got a beautiful strep at a seed swap a few years ago and promptly killed it.
And I love succulents that bloom in the winter. Beautiful rosettes that look pretty year round, and they bloom indoors in the winter when nothing else is blooming.
