Staurogyne Porto Velho care guide
Staurogyne Porto Velho (Staurogyne sp. 'Porto Velho') — medium light, 22-28 °C, pH 5.5-7, no CO2.
Compiled by Aquairi from published sources · Published · Updated
Overview
Staurogyne Porto Velho (Staurogyne sp. 'Porto Velho') is an aquatic plant of the family Acanthaceae, listed in the Aquairi knowledge base as an intermediate-level species. It is typically grown under medium light and without obligatory CO2 injection on any substrate. Compact bushy plant from the Rio Madeira basin that stays under 10 cm tall. Forms tight clumps in the foreground/midground; slow grower preferring rich substrate and gentle flow.
Taxonomy
- Family: Acanthaceae
- Genus: Staurogyne
- Scientific name: Staurogyne sp. 'Porto Velho'
Habitat
Staurogyne is a pantropical genus of Acanthaceae growing on stream banks and seasonally flooded plains. Aquarium species form low compact bushes when grown submersed. In the Aquairi knowledge base, populations associated with this form are recorded from South America.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 22-28 °C (72-82 °F)
- pH: 5.5-7
- GH: 2-10 °dGH
- Substrate: aquasoil
- Maximum height: 10 cm
- Growth rate: slow
- Recommended placement: foreground
Placement
Foreground or low-midground stem; closely planted portions develop into a dense low cushion under bright light and CO2. In the Aquairi knowledge base this form is recommended for the foreground under medium light and without obligatory CO2 injection, using undefined.
Propagation
Cuttings root rapidly; trimming the tops and replanting them increases density and accelerates a foreground bush. Documented propagation techniques for this entry include: stem cuttings.
Common issues
Pale or yellowing new leaves usually indicate iron deficiency; a balanced macro/micro routine and stable CO2 restore the dark-green submersed form.
Propagating Staurogyne sp. 'Porto Velho' by Cuttings
Overview
Staurogyne sp. 'Porto Velho' is a marked compact, low and bushy plant with small green leaves, kept under 10 cm for the foreground and midground. It produces both upright stems and several horizontal stems at the base of the plant, gradually forming a carpet-like patch. It grows somewhat slower than the known Hygrophila species, so propagation rewards patience.
Propagation Method (Cuttings)
Spread this plant by topping: remove the longest upright shoots and replant them, which both keeps the clump low and gives you new starts. Removing tall shoots also pushes the plant to send out the horizontal creeping stems from its base that knit the foreground together.
Step-by-Step
- Identify the tallest upright shoots rising above the carpet.
- Cut them at 5–10 cm with clean scissors.
- Strip the lower leaves from the bottom of each cutting.
- Replant the cuttings into gaps to thicken coverage.
- Leave the base to develop horizontal creeping shoots.
Conditions for Healthy Growth
Staurogyne prefers medium to high light with supplemental CO2 and needs fertilisation to keep its colour and steady growth. A nutrient-rich substrate plus micronutrient dosing supports both the rooted clump and the new cuttings. Gentle flow suits this compact grower.
- Light: medium to high.
- CO2: supplementation recommended for compact, healthy growth.
- Substrate: nutrient-rich, with micronutrient fertilisation.
- Temperature: roughly 22–28 °C, soft to moderately hard water.
Trimming & Maintenance
After the initial trim at planting, the plant may go weeks before needing attention; thereafter new vertical shoots can be removed on a weekly basis. Because growth is slow, expect a slower trim cadence than fast stem plants, and use every topping as a chance to replant and densify.
Common Challenges
- Patience needed — it grows slower than Hygrophila, so coverage builds gradually.
- Loss of compactness if tall shoots are not removed regularly.
- Pale colour and stalled growth when fertilisation is insufficient.
- Sparse base if light or CO2 is too low for horizontal shoots.
