Not sure whether other jurisdictions are affected, but here in the UK, there has been a shortage of myriophyllum guyana for some time. I initially thought that this was merely a localised issue - import costs due to Brexit, etc., but a recent post on the UKAPS forum indicated that Tropica no longer sells this plant.
At this point, I am wondering whether there are some inherent issues with the tissue cultures of this plant, or is it simply due to a lack of demand. I had this plant in the past, and had no problems growing it even without CO2. However, my most recent purchase (a year ago), the tissue culture had trouble adapting to an immersed conditions, even though there was strong lighting and CO2.
I haven't seen any sellers having this in stock for a long while so would be interesting to see if others have the same experience.
