Common Name

Orchid Lily

Origin

Southeast Asia – particularly in Burma (Myanmar), Thailand, Malaysia, and Vietnam. It typically grows in slow-moving streams and forest pools.

Lighting Requirements

Medium to bright lighting is recommended. Under brighter light, the plant may develop striking reddish hues. In lower light conditions, leaves tend to be greener.

Propagation

This plant reproduces primarily via its rhizome, which is bulb-like in structure. Propagation is achieved by carefully dividing a mature rhizome and replanting each section. It is crucial to avoid burying the entire rhizome—only the roots should be in the substrate—otherwise the rhizome may rot. Flowering can occur above water, and although it produces seeds, propagation from seeds is rarely successful in aquariums.

Difficulty

Easy to medium – while generally hardy, it requires proper care during dormancy and rhizome handling.

Short Description

Barclaya longifolia is a graceful and ornamental plant known for its broad, lanceolate leaves that can range from deep red to olive green, depending on lighting and variety. It makes a spectacular midground or background feature in larger tanks. This species may enter a dormancy phase, during which it loses leaves and pauses growth. This is natural and temporary – relocating the plant or slightly adjusting water parameters often stimulates new growth. CO₂ is not essential, but supplemental fertilization and a nutrient-rich substrate will enhance its appearance.

FAQs

• Why is my Barclaya longifolia losing its leaves?

  This species can enter a natural dormancy period during which it sheds leaves and pauses growth. Don’t panic—this phase usually lasts a few weeks. Try slightly relocating the plant or refreshing the substrate to encourage regrowth.

• Can Barclaya longifolia be propagated from seeds?

  Yes, but it’s rarely successful in home aquariums. Flowering occurs above the waterline, and seed germination is inconsistent. Division of the rhizome is a far more reliable method for propagation.

• Is Barclaya longifolia suitable for community tanks?

  Yes, it’s peaceful and non-invasive. However, due to its size, it’s best suited for medium to large aquariums. Avoid placing it with herbivorous fish that may nibble on soft new leaves.

• How do I prevent rhizome rot when planting?

  Ensure the rhizome remains partially above the substrate. Only the roots should be buried. Planting the entire rhizome can trap moisture and lead to decay.

• Does Barclaya longifolia require CO₂ injection?

  Not strictly, but it benefits greatly from it. With CO₂ supplementation and regular fertilization, the plant will produce lusher and more colorful foliage.
