🌿 Staurogyne sp. 'Porto Velho' – Rare Ground-Creeping Foreground Stem Plant

Staurogyne sp. 'Porto Velho', also known as Porto Velho Staurogyne, is a rare and captivating foreground plant with origins in the Brazilian states of Rondônia and Roraima. Introduced to the aquatic plant community only in recent years, this unique species has quickly become a favorite among aquascapers in the USA and Japan for its creeping growth habit, narrow lanceolate leaves, and striking grayish-green coloration with purplish undertones. Despite being relatively unknown in Europe, it's gaining traction as one of the most promising new foreground plants for nature-style and Dutch-style aquascapes.

Underwater, it displays long, pointed, narrow leaves and hirsute light brown stems—clearly distinguishing it from the more common Staurogyne repens. While somewhat slower-growing and more demanding than S. repens, S. 'Porto Velho' excels with proper CO₂ injection, stable nutrients, and moderate to high lighting, forming dense, ivy-like carpets over time.

🌟 Key Features:

🖼️ Aquascaping Benefits:

• Creates an elegant, creeping foreground or low midground carpet

• Offers a deep, earthy contrast with its dark, grayish-green leaves and purple hues

• Pairs beautifully with finer-leaved carpeting plants or light-green stems for visual balance

📦 What You’ll Receive:

Sold as loose fresh-cut plants, bunched plants, or potted plants:

• Fresh-Cut Plants: Approximately 3 individual, loose-cut stems without root

• Bunched Plants: Approximately 3 stems without root bundled with foam and a plant weight

• Potted Plants: Approximately 3 stems without root potted in rockwool and net pot

⚠️ Disclaimer:

Staurogyne sp. 'Porto Velho' is slower to establish than typical carpeting plants and may lose some leaves during initial transition. Consistent CO₂ injection and macro/micro dosing are highly recommended to promote healthy root anchoring and lateral spread. As with many stem plants, selective trimming encourages denser growth and faster propagation.
