Eriocaulon cinereum, Eriocaulon 'Polaris', and Eroiocaulon cinereum 'Polaris'

[BenB]

I've seen people offer Eriocaulon 'Polaris' for sale, I have purchased Eriocaulon cinereum from my LFS. You can see a pic of the cup below from Dec 2024. I just found someone offering a Tropica cup of Eriocaulon cinereum 'Polaris' Pic also below. However, the cup doesn't say Polaris. That's only in the vendor's text. The Tropica web page doesn't say anything about Polaris.

Are they all the same thing?
What do you think?

Ok, it looks like Tropica did sell 'Polaris' at one point, even having the same code on the cup (091TC).

What is notable about 'Polaris'? I wonder if it's a mutation that reverted in TC, which is totally a thing that can happen, and it was easier to just sell it as the straight species, or if the original plant was misidentified? None of this answers your question though.

Yeah, if you go to the page you linked to, it has a link on the right side that takes you back to the page I linked above.

Who knows. I definitely believe IMO that some many of these Buces are the same plant, and people just renamed them to have something special. They do it with coral in the reef hobby all the time. I feel like maybe some of the "unique" Rotala variations might be this as well. Is this the case here? No way to know. It might have just been a case where someone bought E cinereum 'Polaris' and just called it E Polaris for short. I can see me doing that myself. Unintentionally it introduced some ambiguity later down the line.

Ya its possible polaris is a subspecies of cinerium. Cinerium has many different subspecies. I know and had 2 types of what was named polaris. One that I dont have anymore seeded daily for me. The other one which I have right now hasn't seeded at all for the time I've had/have it. The regular cinerium (original) is totally different and seems pretty rare these days along with both polaris'. The regular cinerium spikes out and leaves dont curve downward going outward from what I remember. Its been a long time. The polaris I have right now is so beautiful to me and being it doesn't seed is a great bonus. I hope to mass propagate it.
Here's pics

Mine puts out inflorescences a lot. I wish I had the kind that didn't, but I like these anyway.

I just split mine recently. Its one of my favorite erios. Without the flower stalks they are gorgeous. When they grow out into a full grown erio I can send you one for shipping. Thats if you being in the states? Here are mine now. The old one I had was pretty too but the flowering everyday made it uglier
