Dwarf Baby Tears is one of the smallest aquatic plants available while also proving to be one of the most impressive for creating that lush foreground seen in many stunning aquascapes.

This plant can grow submerged or emersed in dry start aquariums, Wabi Kusa, and when grown in Iwagumi layouts, the vast fields of green creates a captivating effect on any audience.

Dwarf Sagittaria is a popular choice as a foreground plant that adds subtle depth to your aquascape.

Similar to wide blades of grass, it can grow submerged or emersed and can grow high enough to make an excellent mid- or background accent as well.

Easy care - Requires medium light, does not need additional Co2, but high lighting with added Co2 brings out more red tones in the plant.

Rotala H'ra is a new plant to the hobby that makes a delicate and dramatic back or mid-ground accent.

This stem plant has profuse thin, pointed red or orange leaves that typically grow from an ascending rather than upright stem and can grow both submerged and emersed.

Medium difficulty - Moderate to high lighting and additional Co2 will yield the most vivid coloration in these plants.

Staurogyne Repens grows compactly and if given sufficient lighting and nutrients can grow into a thick bush of green foliage.

Commonly used as a foreground or midground plant as each stem will only grow up a few inches in height due to its growth pattern.
