I don't know about you, but when it's this hot, I'm much less likely to spend a lot of time outside. Perfect time to focus on the plants growing indoors.
Indoor plants have requirements that must be met, and the most important one here is light. If you can't grow a plant where there isn't enough light, just don't grow it there.
Make sure you know what kind of light your house plant needs. Observe the light conditions in the location where you'd like to place your plant and then find a plant that has light needs that can be met by the light conditions there.
If you have a spot where you'd like a plant but you've found it's too dark for living plants, consider a silk plant. Some may find it comical, but if you keep killing plants, then this might be the best answer.
