Plants You Haven't Had Luck With - Share!

[Gar]

I'll start.

Lobelia "Cardinal" - Melted after the first day.
Hygrophilia Difformis - Even under high light & co2, it just didn't like me. =[
Jungle Vals - They live, but they don't thrive. I honestly don't know why.
Cabomba - They grow nicely, but then they like, somehow become un-bunched and I can't get it back together for the life of me.

Maybe I just suck, but I don't know. I've never had crypt rot or problems with any other plants - even the Erio type II mpodolon sent me. These plants just don't like me. ;_;

So - what plants don't like you?

[@marko@]

didiplis diandra- grew well but barely, it was trimmed too low, and died.
HC- im on my third batch, the other 2 died (wish me luck)
red cabomba- did good, but then got overgrown by asian ambulia while i was on vacation and never recovered
any ludwiga i tried- they just die
dwarf lotus- did good in low tech, but died when i put it into a bigger high-tech tank. now i tried again, but this time it worked
glosso- died from shading while i was on vacation (i still have 1 stem that is growing, so maybe itll send runners soon)

Hygrophilia Difformis
Cabomba red and green
Ludwiga Repens and just about every variety of Ludwiga
bacopa(cannot remember the species)
java moss(likely due to too high tank temperature)
christmas moss(likely due to too high tank temperature)
dwarf sag(likely because of excel dosing)

Rotala Walichii
Tonnia spieces

[BiscuitSlayer]

Rotala - Red kind. Rotted away mid stem while the top half of the plant was in good shape. Replanted it and the same thing happened again.

Ambulia - It got leggy and sparse. Generally looked like crap after a couple of weeks.

Glosso - Mixed results. It did well at first, but it spread very very slowly. It can't be shaded or it gets very leggy. It also doesn't appear to like excess phosphate.

HC - For me it appears to be a clado magnet. I am going to rip it all up, clean it and replant.

[blazeyreef]

several but...

java moss-always got infested with algae and never seemed to grow, only wither away...also never got it to attach to anything
java fern-I had good luck with it for a few months, but could never get it to attach to anything and it eventualy, as well, withered away
cabomba-grew strait to the top and starting turning pink, then kind of just, started to melt... weird
im sure their are others, im just to tired to think at the momment LOL

I've always had a time keeping dwarf hairgrass clean from cladophora. Can't seem to get enough Co2 pumping through it's density. The grass still grows, just with a little friend alongside

EDIT: Forgot that I had some hitchhiker duckweed with some plants one time. I guess it died, it all just disappeared in a couple weeks

Got mist?

[eyebeatbadgers]

Yes! And I love it, but I'm still having small problems with clado, just in the hairgrass. HC is growing great however, no algae present, in the same tank.

I suspect part of the problem may be the inert substrate could be slowing the growth of the hairgrass, making it more susceptible to algae fixation. In my natural planted tank, with a good nutritive riverbed silt substrate, the hairgrass grows much more quickly, and is algae free. I also use Co2 mist in that tank.

EDIT: for anyone not using mist, I recommend the Gen-X Needle Wheel pump. It pumps 1000lph I believe ( I bought the smallest model), and cost 30 bucks shipped to my door. A deal that can't be beaten!

[Green Leaf Aquariums]

Rotala Vietnam, I acquired some plants from a local and they were infected by a horrible algae I have never seen before. They started growing nice and pink. Then the algae moved in and formed a nice green slime hair.. Man!

[NstyN8]

Hottonia palustris- I received one sample stem during a trade. Never gained any height and remained bushy.
Rotala Macranda- Received as a sample during a trade. The top looked alright; however, the rest of the plant looked decrepit. Grew very slowly. Maybe the plant is suppose to have that sickly look.
Glosso- The plant did well. Unfortunately a pair of newly acquired flag fish consumed most of the bed in 1 day.
Bolbitus- Never took root to the driftwood. Too bright...?

I am experiencing the same.
The soft plants like parrot feather seem tough for me.
Glosso & 4 leaf clover was also a no go.
Pelia..tough to get it in good shape.
Tiger lotus, leaves melted away, it grew new smaller ones and they melted too.

Forgot about that one too. It grows, but not well until it gets to the surface. Very leggy in the bottom half of the tank.

[cah925]

I can't grow anubias (so far) without algae. I currently have some growing in a low light short photo period tank. Still too early to tell if I will have any luck.

Parrot feather is one that I cannot grow at all. It always falls apart and then turns to mush.

[pweifan]

Parrot's feather - (I feel better about not being able to keep it...) Mine wouldn't turn to mush, but the bottom would always drop leaves. If I'd grow 3" of new leaves in a week, the bottom 3 inches would drop its leaves.
