Lazarum russell-smithii (A.Hay) M.D.Barrett, A.Hay & Hett.

• Genus: Lazarum russell-smithii
• Botanical Background: Originally described by A.Hay and later revised by M.D.Barrett, A.Hay & Hett, this species is named in honor of botanist Russell-Smith, reflecting its importance in studies of Australian wetland flora.

• Geographical Range: Indigenous to tropical wetlands in Australia
• Environment: Thrives in warm, humid climates with moist, well-draining soils. It favors partially shaded habitats that receive consistent moisture and mimic its native wetland conditions.

Leaves

• Medium-sized and range from lanceolate to elliptical
• Smooth texture with distinctive variegated patterns in shades of green that enhance their ornamental appeal

Inflorescence (Spadix & Spathe)

• Produces a typical aroid inflorescence featuring a slender spadix encased by a protective spathe
• Modest flowers primarily serve to attract insect pollinators

Growth Habit

• Terrestrial plant that grows from a rhizome, forming dense clumps over time. Its compact habit makes it suitable for container cultivation as well as integration into wetland garden displays

Light Requirements

• Provide bright, indirect light to maintain the vibrancy of the foliage without risking leaf scorch

Watering & Humidity

• Keep the soil consistently moist, replicating its native wetland conditions
• High humidity is essential, but avoid waterlogging to prevent root rot

Soil & Potting Mix

• Nutrient-rich, well-draining potting mix enriched with organic matter is ideal
• Ensure containers have ample drainage to support healthy root development

Temperature & Fertilizer

• Ideal temperatures range from 65°F to 85°F
• Balanced and slow-release fertilizer applied during the growing season promotes robust growth

Division

• Propagation is best achieved through rhizome division during repotting
• Each division should include an active growth point to ensure successful establishment

Seeds

• Propagation is possible but less common due to variable germination rates and a longer maturation period compared to vegetative methods

Typical Issues

• Spider mites, and mealybugs
• Fungal root rot, particularly if the plant is overwatered or kept in poorly ventilated conditions

Treatment Recommendations

• Use organic insecticides such as neem oil or insecticidal soap to manage pests
  
• Maintain proper watering practices and ensure good air circulation to prevent fungal infections

• Named in honor of botanist Russell-Smith, Lazarum russell-smithii offers insights into the adaptive traits of wetland aroids in Australia and contributes to the understanding of regional biodiversity

• Its unique, intricately patterned leaves and robust, clumping growth habit, which make it a striking addition to specialized tropical and wetland plant collections

Wild Population Status

• Specific conservation data are limited
• Preservation of native wetland habitats is critical for the survival of Lazarum russell-smithii and similar species

Market Availability

• Relatively rare in cultivation and is mainly available through specialized nurseries and botanical collections
