I have an ability to kill most house plants.
Thankfully over the past year I have managed to keep alive six obviously very hardy plants. These plants make the air in the house better, of that I am convinced, and are quite beautiful to look at. And thankfully they seem able to survive at least seven to ten days between waterings.
Now that I think of it, it has been at least a week since I last watered them. Off to water the plants...
