That plant with the ancharis at the very left? It's not wisteria.
wisteria looks like this:
It looks kind of like a dandelion's leaves underwater. Or a fern.
The plant you have, it's leaves are round and a little spiky at the edges... it reminds me of the leaves on a rose. I'm not sure what it is. It might not be aquatic.
The best way to be sure you're getting 100% legit aquatic plants is to buy directly from a grower. =]
A great place to buy high quality plants from a reputable dealer (that sometimes throws in extras) is Planted Aquariums Central.
The woman that grows the plants is really dedicated and her customer service is top notch! =] I just bought from her and my plants are coming in on tuesday! =] You can get 6 whole stalks of Ancharis for only $2.89!
I see you already have some and it's a great plant! Really cleanses the water and in low light conditions too! =]
The best part about the site is that the owner is giving everyone who's on www.bettafish.com
a 10% off dicount if you use the code BETTAFISH
at checkout! :D (yes you need to type it in all-caps. =])
Shipping was only $8.00 for me! =] I'm not sure if it's a flat rate though. I know that she expidites all of her packages so it's always 2-3 days for shipping. =]
My entire order was about $25.00 but I bought Water Sprite, Ancharis, Java Fern, and Anubia Coffeefolia(that was the expensive plant! >n< But it's SOOOO gonna be worth it! <3 So pretty! <3). And when I ordered I don't think I got the discount. =]
If you ordered just a few fast growing plants like Didiplis diandra(another great value plant! You get 10 stems for only $2.89 :D),
Water Sprite, Ancharis (again this is a great value plant! :D), and actual Wisteria then your bill would be lower and you'd be good to go. =] Also YOU can get the discount so you can take 10% off of your purchase. =]
Also if you have the cash I recommend Creeping Jenny. =] It looks so pretty! <3
But yeah. I suspect the plant is not actually aquatic. I could be wrong though. But I know FOR SURE that it's not Wisteria. =]
