10 Easiest Flowers to Grow Indoors

9. Crown of Thorns

This plant, the next on our list of easiest flowers to grow indoors can take a lot of neglect, so if you’re like me and forget about your plants, you should give this a look. It can basically live without being nurtured as long as it gets enough light. It blooms during the winter, so it’s great for holidays. It survives well in temperatures of about 50-70ºF. In fact, lower temperatures help it start to bloom bright red flowers. Occasional watering keeps the Crown of Thorns happy.
