In this article I will present some data and statistics about indoor plants. First, I will present the results of some larger surveys that have surveyed millennials, independent garden centers, etc.

I also collected my own data and at the end of the article I will show you the results of a survey that I conducted myself on Instagram, which described in detail how many houseplants my followers have.

10. How many indoor plants do people grow?

I did a little of my own research and asked my own followers on Instagram.

In December 2021, I conducted a survey among my followers via Instagram stories, in which I asked how many houseplants my followers grow. A total of 1,581 people responded and here are the results.

To help you interpret the chart, select the largest slice of the pie chart, the orange. A total of 514 people claimed to own 11 to 20 houseplants, which are shown in orange in the graphic. This is 33% of the total responses.

The smallest piece of the cake, which is depicted in purple, indicates that 5% of the respondents (a total of 85 people) own more than 200 indoor plants.
