Alocasia Lauterbachia


Originating from the shaded, moisture-rich floor of tropical Asian rainforests, Alocasia lauterbachiana 'Purple Sword' stands out as a dramatic architectural showpiece. Named for its long, lance-shaped leaves that resemble serrated blades, this species features glossy, deep green upper surfaces offset by rich purple-maroon undersides and distinctively mottled, textured petioles. Evolutionarily adapted to high canopy humidity and filtered understory light, its narrow foliage points skyward in a tight, upright habit, making it an ideal choice for filling tall vertical spaces in modern interiors.

  • Toxic to pets and children
  • Repot once every 2 years
  • Fertilize once a month
  • Requires frequent watering
  • Bright, indirect light

About Alocasia Lauterbachia

Origin

Hails straight from the warm, tropical rainforests of Papua New Guinea, soaking up humid canopy vibes.

Air Purifying

Yes! This bold, architectural diva works quietly in the background filtering common household toxins and boosting indoor oxygen levels.

Toxicity

Keep curious paws away! Like all Alocasias, it contains insoluble calcium oxalates, making it toxic to cats, dogs, and humans if chewed or swallowed. 

Caring for Alocasia Lauterbachia

Watering

Water when the top 25–30% of the soil has dried out. This amigo loves consistent, wrung-out sponge moisture, but hates standing in soggy soil or drying out bone-dry. Serve filtered or rainwater to keep its leaf tips pristine!



Light and Placement

Thrives in bright, indirect light to fuel those tall, upright leaves and keep its purple undersides vibrant. Protect it from harsh direct afternoon sun, which can scorch those long sword-like edges.

Nutrition

Treat it to a snack every 3–4 weeks during spring and summer using a balanced liquid houseplant fertilizer diluted to half-strength. Skip the food during fall and winter when it takes a seasonal rest.


Repotting

Level up its home every 1–2 years in spring when roots start crowding the pot. Use a chunky, well-draining aroid mix with plenty of orchid bark and perlite, moving up just 1–2 inches in container size.

Pruning and Flowering

Trim off old, yellowing outer leaves right at the stem base using clean, sharp shears to direct energy into fresh upright spears. Indoor blooms are rare, but those long, wavy leaves are the real showstopper anyway!


Alocasia Lauterbachia SOS

Illness

Keep an eye out for spider mites, thrips, and root rot from overwatering. Low humidity will cause crispy brown edges, so keep the air extra moist and cozy!
