1 month update: Whatever it is, it looks like hydrocotyle verticillata but the stems are about 1/8 inch thick and it grows 1-2inch big leaves that reach the top of my 22 inch deep aquarium. Definitely not the 1-3 inch tall plant I expected. It looks alright though, i guess. Like big dr seus umbrellas. lol
"one portion" wound up being like 10 individual rhizome sections with a big old emergent leaf on each.
The rhizomes were easy to plant, and the emergent leaves are not melting---they're pearling! All of the rhizomes have already grown new submerged leaves.
It looks super cool. One of my favorites and growing like a weed within 1 week.
Waited a week to see progress. Placed semi-emerged in my overflow, they are really taking off with new leaves from several different nodes
Added three of these to my Walstead style tank and they have completely taken off. They arrived in healthy condition with good looking roots and no browning. A couple of smaller stalks melted when first added but it is a new tank so that was to be expected. Literally just after a couple of days several new stalks had grown and so far three leaves have actually grown out of the water which adds a nice aesthetic. Would highly recommend.
