Anthurium carlablackiae Wu1 S1
Anthurium carlablackiae ‘Wu1’ S1
Anthurium carlablackiae ‘Wu1’ S1 is a seed grown offspring of the Wu1 carlablackiae clone, combining the elegant elongated foliage, velvet texture, and refined venation associated with Anthurium carlablackiae.
This plant is already showing beautiful characteristics at a young stage, including an elongated heart shaped leaf, olive bronze emergent coloration, and sharply contrasting pale pink to silver venation. As the foliage hardens, leaves deepen toward richer green tones while maintaining their velvety appearance and defined vein structure.
Because this is an S1 plant, it was produced by self pollinating the Wu1 parent. Each seedling can express the genetics slightly differently, so mature leaf shape, darkness, venation, sinus, and emergent coloration can vary from plant to plant.
What You’ll Receive
One live Anthurium carlablackiae ‘Wu1’ S1 plant.
Your plant will be carefully packed to help protect the foliage, root system, and active growing point during transit.
Plant Highlights
Elongated velvety foliage
Strong Anthurium carlablackiae characteristics
Bronze to olive emergent leaves
Bright contrasting venation
Potential for increasingly long and narrow mature foliage
Elegant heart shaped leaf form
Seed grown S1 offspring of the Wu1 parent
Each plant develops its own individual expression of the genetics
Light
Provide medium to bright indirect light.
Bright filtered light encourages healthy growth, strong coloration, and progressively larger foliage. Avoid prolonged harsh direct sunlight, particularly during the hottest part of the day, as velvet leaves can scorch.
Water
Water thoroughly once the upper portion of the growing media begins to dry.
Keep the root zone consistently lightly moist without allowing it to remain constantly saturated. Allow excess water to drain freely after each watering.
Avoid repeated periods of complete dryness, particularly while the plant is actively producing new foliage.
Humidity
Moderate to high humidity is preferred.
Humidity around 60 percent or higher helps support smooth leaf emergence and healthy foliage development.
Higher humidity can be especially beneficial while new leaves are expanding, but good airflow should always accompany elevated humidity.
Growing Media
Use a chunky, airy, well draining Anthurium mix that holds some moisture while maintaining plenty of oxygen around the roots.
A combination of tree fern fiber, orchid bark, coco chips, pumice, perlite, and coco coir works well.
Avoid dense growing media that remains saturated for extended periods.
Temperature
Warm temperatures are ideal, generally around 65 to 85°F.
Protect from frost, cold drafts, and prolonged exposure to temperatures below approximately 55°F.
Consistent warmth encourages stronger root development and more regular leaf production.
Airflow
Provide gentle airflow, particularly when growing in higher humidity.
Good circulation helps prevent stagnant moisture around the foliage and growing media while allowing the plant to benefit from humid conditions.
Fertilizer
Feed lightly and consistently during active growth using a diluted balanced fertilizer.
Regular light feeding can support healthy root growth and progressively larger foliage.
Periodically flushing the growing media can help prevent fertilizer salts from accumulating around the roots.
Growth Habit
Anthurium carlablackiae is known for developing elongated foliage that becomes increasingly elegant with maturity.
Young plants can begin with shorter, broader leaves, while successive growth may become longer, narrower, and more defined as the plant establishes.
The mature appearance of an S1 seedling cannot be predicted exactly, which makes watching each plant develop part of the appeal.
Emergent Color
Fresh foliage can be one of the standout features of this plant.
New leaves may emerge in shades of bronze, olive, copper, reddish brown, or muted burgundy, often with pale pink to silver veins that appear especially pronounced before the leaf fully hardens.
The leaf gradually transitions toward its mature green coloration as it finishes developing.
What S1 Means
S1 means this plant is a first generation selfed offspring of Anthurium carlablackiae ‘Wu1’.
It is not a clone of Wu1. Instead, the Wu1 plant served as both the pollen and seed parent.
This allows desirable Wu1 characteristics to appear in the offspring while still creating natural genetic variation between seedlings. Individual S1 plants may differ in mature leaf length, width, darkness, sinus shape, venation, and emergent coloration.
Anthurium carlablackiae ‘Wu1’ S1 offers the elegant form and velvet characteristics associated with carlablackiae while giving each seedling the opportunity to develop into something uniquely its own.
