Rotala rotundifolia 'H'ra'

Rotala rotundifolia 'H'ra' key facts

Growing Difficulty

Intermediate

Lifespan

Perennial; maintained by replanting cuttings

Size

About 3–20 cm tall (often creeping)

Watering

Moderate CO2 and good fertilisation bring out the orange colour

Lighting

Grows in medium light; strong light makes it creep and deepens the orange.

CO2 & Fertilizer

Moderate CO2 helps, and good fertilisation improves colour.

Water Temperature & Quality

Manage temperature and water as for other Rotala.

Substrate & Attachment

Plant in the substrate; its creeping habit suits midground cushions or the foreground.

Trimming & Propagation

Propagate by replanting cut stems.

Cautions

It resembles the standard species and 'Green', so check the name. Never release plants into the wild.

About Rotala rotundifolia 'H'ra'

Rotala rotundifolia 'H'ra' is a narrow-leaved Rotala variant that turns warm orange and creeps along the substrate under strong light, CO2, and fertilization. An intermediate-level aquatic plant maintained long-term by trimming and replanting.

7 things to know before growing Rotala rotundifolia 'H'ra'

1. 1Give It Strong Light

   The stronger the light, the more vividly this plant colors up, while low light tends to keep it greener and more upright. Placing it where light reaches well in the foreground to midground brings out both its orange hue and its creeping growth habit.

2. 2CO2 Boosts Coloring

   Adding CO2 promotes photosynthesis and encourages the warm orange coloring along with the low, creeping growth form. It can still be grown without CO2, but the color and carpet-like spread will typically be more muted.

3. 3Fertilize Regularly

   Root and liquid fertilizers both influence coloring and growth. When strong light, CO2, and fertilization all come together, the plant is more likely to form its characteristic orange carpet.

4. 4Use Nutrient-Rich Substrate

   Since it roots along the stem as it spreads, a nutrient-rich substrate helps it establish and grow steadily. A reasonably deep substrate layer also makes planting and replanting cuttings easier.

5. 5Trim and Replant

   Trimming overgrown stems and replanting the cut tips — a technique often called replanting — lets you maintain its shape and enjoy it over the long term. As a perennial, it responds well to a regular trimming routine.

6. 6Planting Tips

   Because the stems are thin and somewhat delicate, insert them carefully into the substrate when planting to avoid damage. Planting several stems together helps them root more reliably and gives a fuller look early on.

7. 7Keep Temperatures Stable

   As with most aquatic plants, sudden swings in water temperature can disrupt growth. Keeping the temperature stable while balancing light, CO2, and fertilization is key to bringing out both the orange coloring and the creeping growth habit.

Frequently asked questions about Rotala rotundifolia 'H'ra'

Q.Is this a good plant for beginners?

A.This variety is generally considered suited to intermediate keepers rather than complete beginners. It needs conditions like strong light and CO2 injection dialed in, so some prior experience with aquatic plants is helpful.

Q.How big does it get?

A.It typically reaches about 3 to 20 cm in height, and tends to trail or creep along the substrate rather than growing straight up. Regular trimming lets you control its height and spread.

Q.Why isn't it turning orange?

A.The orange coloring depends on having strong light, CO2 injection, and fertilization all present together. If any of these is lacking, the plant tends to stay more green, so it's worth reviewing your setup.

Q.What does replanting cuttings mean?

A.It refers to cutting overgrown stems and replanting the tips into the substrate to propagate the plant and keep its shape tidy. Since it's a perennial, repeating this process lets you enjoy it for a long time.

Q.How is it different from other Rotala varieties?

A.It's a variant of Rotala rotundifolia with somewhat narrower leaves and a trailing, creeping growth habit rather than growing upright. Under the right conditions it can also form a distinctive orange, carpet-like mat.
