Anthurium jenmanii ‘Green Jade’

Cultivated origin of Anthurium jenmanii ‘Green Jade’

‘Green Jade’ is a cultivated selection of Anthurium jenmanii, distinguished in cultivation by its evenly deep-green foliage.

Across its wild range—from Trinidad and Tobago through Venezuela and the Guianas to northern Brazil—A. jenmanii occurs on trees, rocks and the forest floor in warm, moist conditions. Its short stem produces the self-supporting bird’s-nest form seen in this selection.

Growing Anthurium jenmanii ‘Green Jade’

• Light and shape: Give bright indirect light from above when possible. Rotate the pot in small stages if all new leaves are leaning strongly toward one side.
• Temperature and humidity: A stable 18–27 °C suits routine growth. Protect it when prolonged temperatures approach levels below 15 °C. Keep the surrounding air in the 50–60% range and allow mild circulation.
• Water and crown: Water after the upper mix begins to dry, then empty the saucer and remove any water held between the youngest leaf bases.
• Potting mix: Use a mix that holds some moisture while allowing excess water to drain freely.
• Feeding: A light feed is sufficient while the rosette is making fresh leaves and roots. Reduce feeding as growth slows.
• Pot choice: Use a stable pot only slightly wider than the root ball. A very large container can stay wet long after the broad leaves suggest a large plant.
• Repotting: Repot when roots fill the container, keeping the short crown at the same height and the leaf bases above the mix. Renew compacted mix during active growth.
• Leaf care: Clean hardened leaves with a soft damp cloth, supporting the leaf from below. Do not wipe or reposition a leaf that is still opening.
• Propagation: A rooted basal shoot or a healthy stem section carrying an active growing point can be used to make new plants.

Troubleshooting ‘Green Jade’

• The whole rosette leans: Improve the direction of the light and turn the pot gradually. If the container is unstable, place the undisturbed root ball in a heavier outer pot.
• Outer leaves yellow while the pot remains heavy: Stop watering until the root zone begins to aerate, then inspect for compacted mix or soft roots. Repot only when the root condition shows that the current substrate is failing; dry brown bands with a dry root zone need a full watering and, when salts have built up, a thorough flush.
• White cottony clusters hide between leaf bases: Separate the plant from the collection and expose the sheltered leaf bases so you can remove visible mealybugs. Apply a treatment labelled for mealybugs to the sheltered leaf bases and other protected areas, then repeat it at the intervals stated on the label for the full course; the mealybug treatment guide gives the full sequence.

Anthurium jenmanii ‘Green Jade’ is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

Anthurium jenmanii: name and meaning

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix. Jenmanii honours the British botanist George Samuel Jenman.

Heinrich Wilhelm Schott established the genus Anthurium in 1829 in Wiener Zeitschrift für Kunst, Literatur, Theater und Mode, volume 3, page 828.

Heinrich Gustav Adolf Engler first described Anthurium jenmanii in 1905 in Das Pflanzenreich, IV, 23B, page 72.
