Botanical name: Cymbopogon citratus
Dimensions of the 3 L Air-Pot container are 195 mm diameter × 215 mm high.
The lemongrass pictured is a clump of three and with new growth already emerging.
In spring it will really respond to the increased aeration this container provides, and should grow out well once the weather warms. Please note though, that it may grow too well for this size and will probably require repotting come summer. The 9 L Air-Pot container is a great long-term size for this plant.
