Eleocharis species, question

If annual plants means they will die after flowering.
I bought mine (not sure if they're Japonica or Echinosperma)
while they were flowering. Still doing fine, 4-5 months now.

 

Hi,

Annual plant I think generally refers "seed to seed" usually a growing season.

I don't think Blyxa is an annual, since they can be propagated via cuttings.

Lilaeopsis brasiliensis would be half the height of Blyxa Echinosperma

Eleocharis acicularis is I think the choice you want; I don’t believe eleocharis parvula will get much taller than Lilaeopsis brasiliensis. The other Eleocharis', I am familiar with grow much taller.

Eleocharis will certainly be easier to grow than Blyxa Echinosperma. If you can get it and don’t mind a bit of a challenge, Blyxa japonica is an interesting plant (I have no direct experience with B japonica).

If you go with Blyxa, I would recommend dense planting.

Depending on the look you’re going for a little Monosolenium tenerum attached to rock interspersed with either eleocharis parvula or Eleocharis acicularis makes for a nice look.

When it comes to matters of artistic interpretations, I am likely the last entity you should trust.
