Pogostemon stellatus ‘Octopus’: leaves are very long, narrow, ribbon-like. This plant leaves emerge in whorls (several leaves from the same node), giving the characteristic “octopus tentacle” appearance. .Its stems and leaves are bright green.
When submerged, you’ll usually see much longer, more flowing leaves. Faster vertical growth which can grow to 30–60 cm or more. A bushier look after repeated trimming.
