The swords in the scape picture look immature, like they will eventually get much larger and need replaced in order to keep the nice scale.
I am also wondering about large rosette plants in aquascaping because every aquascape picture I look at has small plants or large plants with small leaves. I guess that makes the scape look larger.
I am a fan of aponogeton ulvaceus and the amazon sword and have a 120g. But will I have an effective scape? Or will the large plants move the eye away from my driftwood that is off center and large?
