Flowering
Ongoing blooms every 4-6 weeks once maturePlant produces characteristic dark burgundy spathes (bracts) with yellow spadices (flower spike); spathes emerge from leaf axils and gradually open over 1-2 weeks
Maintain consistent conditions; do not move plant frequently as it may drop buds; provide stakes or moss pole for aerial roots; continue regular watering and humidity
Mature Plant
Indefinite with proper careWell-established plant producing regular flower spathes and healthy foliage; may develop aerial roots extending from stem
Support with moss pole or stake; rotate plant monthly for even growth; repot every 1-2 years in spring; prune dead leaves and spent flower spathes at base; maintain fertilizing schedule

Harvest Tips
Anthuriums are ornamental plants; cut spathes (flowers) for indoor arrangements when fully colored and firm, typically lasting 4-8 weeks in a vase with fresh water. Leave at least 3-4 nodes on the stem when harvesting. Spathes can also be left on the plant to develop berries if cross-pollinated, though this is rare indoors. For maximum plant vigor, remove spent spathes at the base of the stem.
Fun Facts
- 🌱 The 'Tera' cultivar is a relatively recent hybrid bred for its exceptionally dark, almost black spathes that shimmer with an iridescent metallic quality—far darker than traditional red or pink Anthurium varieties.
- 🌱 Anthurium spathes are not true flowers; they are modified leaves (bracts) that surround the true flower spike (spadix). The tiny yellow structures on the spadix are the actual flowers, which produce the berries.
- 🌱 Anthuriums can live for decades as houseplants with proper care, and mature plants develop impressive aerial roots that can be trained along moss poles or allowed to develop naturally for a jungle-like aesthetic.
