Pogostemon erectus

  Pogostemon erectus forms compact groups of bright green, conifer-like stems. Pogostemon erectus is suitable as a background plant and creates a wonderful focal point in both smaller and larger groups. 

You are buying  1  pot full of Erectus.

Potted plants are much better to start with as they have a full root system already established which will help them acclimate to your tank much better and less likely to go into shock.
