Now this is a HOT Plant... I was fortunate enough to get my hands on this plant at the Aquatic Experience.... I have had it for the past three months. I have never had a plant with SPIKES before. Yes- when this plant is at "full grow mode" that is- Full bright light and CO2 - It's leaves look like small green spikes! Pogostemon Erectus is growing in my 20 long in full sun with occasional CO2. Here is what the German Supplier has to say about it.... "Pogostemon erectus is another new arrival from India. This stem plant produces very elegant needles in beautiful light green. It is not difficult to cultivate if you provide enough light and CO2. (the needles love the CO@ :) For aquascaping purposes, this Indian beauty mixes very will with red and brown-hued plants. It grows at moderate speed. Feel free to radically prune a group of plants- the stems will soon produce new side shoots, and your plant will be thicker and more compact." Again- This is a CO2 loving plant, but is by far one of the coolest plants I have seen in awhile. Unlike other CO2 needing plants, when you give this plant CO2- It THRIVES- not just maintains. Get some!
