Awesome question, we're glad you asked. Given the nature of our plant shop, we're constantly moving plants in and out of the shop, making it difficult and borderline impossible to keep an exact picture of each plant. In addition to the constantly rotating crop, we often grow in batches of 6, 12, or sometimes more! With this quantity we are unable to take a photo of each and every plant. The photos that we attach to each product listing is going to be of a plant that represents the average size and fullness of that set of plants. Some may be slightly larger or smaller, but in general, similar.

We are not responsible for orders that are placed and damage is incurred to the plant if a heat pack is not purchased.
