“Little Pickles” is the common name for Othonna capensis. It is a succulent in the Asteraceae family (genus Othonna).
The leaves (which are fleshy) look like tiny pickles and it ranges in color (green to pink to purple) based on the environment. I grow this outside in a pot right against my house so the eaves protect it from rain and snow. It is hardy—it can handle 30 degrees to 105 degrees Fahrenheit in my experience (Northern California).
I have noticed that the plant is purple when in harsher conditions (such as cold or hot or too wet/dry), and green when the weather is nice (60-80 degrees, not too wet or dry). This is because the plant changes color based on its stress level.
To demonstrate this change in color, browse the photos in this post, which I took of my plant through time. I’ve provided information in the caption of each image.
