Purple ambulia
Measured underwater with an Apogee MQ-510at this plant’s position. Working ranges are practical reference figures, not biological thresholds. The full survey sets out how the number was taken and what it does not establish.
Whorled stem; fast, upright, large by aquarium standards.
Rear-right, where its size gives the back of the scape height.
Purple to violet underside with green above; a strong color contrast.
General to the species. What this plant has actually done in this aquarium is recorded under observations.
Fast enough to need regular topping or it reaches the surface.
Nothing recorded specific to this plant in this aquarium yet. The scape is still growing in; observations are added when there is something specific to report rather than to fill the section.
Photograph pending. Planned: a current photograph at matched camera settings, repeated at intervals so color can be compared across time rather than described.
