Harvest Tips
Anthuriums are ornamental houseplants, not harvested in traditional sense. Cut flowers last 2-3 weeks in a vase when fully mature and colored. To encourage more blooms, deadhead spent spathes at the base of the stem. Allow plant to establish 4-5 mature leaves per stem before cutting flowers to ensure plant vigor.
Fun Facts
- 🌱 Anthurium flowers aren't actually flowers—the colorful 'petal' (spathe) is a modified leaf, and the true flowers are tiny and located on the finger-like spadix in the center.
- 🌱 The name 'Anthurium' comes from Greek words 'anthos' (flower) and 'oura' (tail), referring to the distinctive tail-like spadix.
- 🌱 Anthuriums can bloom nearly year-round indoors under stable conditions, with flowers lasting 2-3 months each—far longer than most cut flowers.
