In order to maintain our established quality, we have opted to discontinue the sale of this plant in potted rockwool, as the rooted options are of superior quality.


I found this EXTREMELY good article on for you. If you have the time - READ IT ;)


This the RED form that have exceptional red colouration.


"Common name: Pink Baby Tears, Roundleaf Toothcup, Pink Rotala, Dwarf Rotala


Distribution and habitat:

It originate in southeast Asia. In the wild, this species is often found in a semi-emersed state at the edges of rice paddies and in moist locations.

Its Latin species name rotundifolia means “round-leaved”, however, the round leaves that gave the plant its name are only found in its creeping swamp form. Their leaves have an elongated oval or even linear shape.



This species has both submersed (underwater) and emergent (out-of-water) forms, which differ in a number of characteristics. The small leaves – less than 2.5cm (1 inch) long – are arranged in groups of two or three around plants’ pink stems. However, emergent plants has fleshy, bright-green and rounded leaves; submersed plants has darker green or reddish leaves that are thin and lanceolate – sword-shaped. Growth habit differs between the forms as well. Low-growing populations of emergent plants creep along shorelines and banks, with plant height rarely exceeding 15cm (six inch). Submersed plants form tight, mounded colonies in water as deep as 1.8m (6 feet), but they eventually grow to reach the surface of the water, where they form dense mats that block light penetration and impede water flow.

This is a favorite of the aquarium and water garden industries, being appreciated for both its leaves and flowers.


Aquarium care:

An ideal aquarium plants for beginners. The species is a typical example of a rapidly growing stem plant and responds favorably to frequent and even heavy pruning. This plant can be used as regulator in a newly cycled tank. Pruning must be done on a frequent basis as the side shots will grow considerably under good condition, keeping the leaves at the base of the plant away from the light. Without pruning, the plant will take a bushy appearance which could be suitable for fry or breeding tanks. Although they are difficult to grow beyond the water surface; established plants will flower small, purple flowers above the water line.

This plant looks best when planted in large groups. Once it is flourishing, it propagates easily through new shoots or cuttings. They are are best placed in the background of a tank.

It is considered to be a fragile plant that should be excluded from environments with very active or large fish that may damage their fragile stems.



They will tolerate large fluctuations of both pH and General Hardness (GH). Ideally, the pH should be between 5.5 and 7.5, with dH below 15.



Rotala rotundifolia can be plated directly on the bottom substrate of the aquarium. The substrate could be plain sand or small granulated gravel. Soil fertiliser is not required to grow this plant successfully.

Rotala rotundifolia is beautiful in clumps, though have to have enough space between stems when planting. Cut plant stem above lead strip with sharp scissors and strip the bottom 4-5cm of leaves from the stem. Individually insert plant into substrate. Care should be taken not to damage the stem. It is recommended to use tweezers to plant them.



Low or medium light will produce a somewhat lanky, yellow-green specimen. This species requires a moderate to high level of light at 3.5 to 5 watts per gallon provided by full spectrum (5000-7000K) bulbs.



Water temperature should be below 30°C (86°F), but not lower than 21°C (70°F).



Rotala rotundifolia plant displays the most beautiful colours at a low nitrate level (5 mg/l) and high phosphate and iron/micronutrient levels. Varying fertiliser doses bring colour hues from pink to yellow. Maintaining nitrates below 5 ppm and phosphates above 1 ppm will further enhance this appearance.


Pond care:

Rotala rotundifolia is a tropical species and is not considered cold-tolerant. However, emergent populations cultivated outdoors die back after multiple hard freezes during winter and then quickly regrow when spring arrives. In temperate zones it may even survive mild winters in a pond.

It can be grown emerse in shallow water where it will flower. Masses of dainty pink flower spikes are produced Spring through Autumn. It is also capable of producing a heterophyllous growth form – different in form and coulour for aerial leaves compared with the submersed ones.

This plant grows to 15cm (6 inch) in height and usually is placed in water to 20-30cm (8-12 inch) deep.



The propagation of Rotala rotundifolia is easy: simply cut the top half of a strong stem and gently replant it in the substrate after removing any leaves from the last node of the stem. The parent stem will quickly develop new shoots and the newly planted cutting will quickly develop a root system. Over time, this topping process will develop lush, bushy plants.
