I bought a small number of stems of Eriocaulaceae sp. ‘Type 2’ at a GWAPA auction a few months ago. This Eriocaulaceae doesn’t look much like many of the other Eriocaulon (pipewort) species that are tearing through the hobby. While the plant looks like a regular stem plant, it really does seem to populate by a form of horizontal runner, where vertical stems grow from the base runner. That said, the plant does bush up quite nicely, and give a very similar effect to that of Stargrass (Hetheranthea zosterifolia), except that it doesn’t seem to grow as prolifically.

Because of its growth by runners, the plant doesn’t shoot to the water’s surface like most other stem plants, which is great for someone like me, who often tires of trimming. I do want to note that while I say that Eriocaulaceae sp. ‘Type 2’ extends by runners, it has most definitely not been as pervasive (invasive really) as something like Sagittaria or Vallisenaria that are known to start popping up all throughout your tank. The Eriocaulaceae runners all stay above the substrate.

If you can get your hands on this plant, I definitely would recommend experimenting with it, as it has lots of aquascaping potential.

I recently planted some Pogostemon yatabeanus outside in my raised brick pond, and just as it often is in my 75G aquarium, it’s the fastest growing plant in my pond. So much so, that it’s grown right up out of the water. Of course, I did cheat a little bit by transplanting some stems that were already starting to grow emersed from my 75G, hence the deformed leaves, burnt by my light strip, but plenty of others have since grown up out of the water.

It’s interesting to see how, when emersed, the stem is a nice red color, where submersed it’s much more subdued. The leaves are much waxier above water, while below water, the stems tend to lie horizontal to the water’s surface, sending vertical side-shoots out of the water.

I have no doubt that before long, I’ll be posting about Pogostemon yatabeanus flowers!

Previously, I’ve posted pictures of my Blyxa aubertii flower. Now, I’ve noticed that some of the Blyxa Japonica, that has been floating toward the top of the surface for some time, has also flowered! From my untrained eye, it’s quite difficult to tell any difference from the two flowers, but I suppose that why the two plants are so closely related.

In any case, it’s always nice to open up your aquarium hood, and see a pretty little flower waiting there for you.

What may be even more incredible is that this is flowering under 1.5 year old normal output flourescents that are being overdriven. I have a mix of 6500k and 10000k temperature bulbs. I’ve noticed in other tanks that 10000k bulbs have caused flowering, so I’m guessing that these bulbs are holding up okay, even though they’re being overpowered.

At the December GWAPA meeting, I was fortunate enough to obtain Pogostemon yatabeanus in the mini-auction that we have at every club meeting. P. yatabeanus is an Austrailian plant, from the same reknowned genus as Pogostemon stellatus, formerly Eusteralis stellatus. This particular species reminds me more of the broadleaf variety of P. stellatus, in that it’s a little bit larger of a plant, except that it stays a beautiful bright green instead of bronzing under bright light. It doesn’t seem to be particularly demanding if kept in your typical high-tech setup.

I currently have the plant in my 75G, planted in Soilmaster Select ‘Red’, with pressurized CO2, high-light, and regular dosing. In this environment, P. yatabeanus might be the fastest growing plant in the tank. Young stems stay rather slender with narrower leaves. Older stems can grow quite thick, with leaves that become longer and fatter, similar to how P. stellatus ‘broadleaf’ grows. When you trim P. yatabeanus and leave the lower portion in the substrate, 2-3 new stems start to grow out of the incision.

Due to this plant’s size, I don’t know if I’d recommend it for a smaller tank, but in a larger tank I think it’s the perfect ‘green’ companion to plants such as limnophilia aromatica, pogostemon stellatus ‘broadleaf’, etc… If you can get your hands on this plant, please give it a try.

I few months ago, I bought a plant from SCALES that was labeled “Rotala indica ‘Red’.” I believe this plant is probably the same thing as Rotala sp. ‘Colorata,’ but at least one GWAPA member believes this is the “real” rotala indica. Either way, this is a gorgeous stem plant that doesn’t need a ton of light to get some very vibrant red tones.

I’ve also noticed that this rotala will start to grow horizontally much more readily than many other rotala’s I’ve tried. As it does this, it sends up multiple vertical stems which can eventually be trimmed and replanted as their on stalk. The plant definitely takes off when CO2 is added, but it seems to grow, albeit much slower, without the added carbon injection. Right now I’m growing this using all SeaChem products in my 20L.
