Identification & Classification
Color & Surface
Vibrant "highlighter yellow" scales. They turn greenish when wet because the yellow skin becomes see-through, revealing the green algae inside.
Shape & Form
A scaly "crust" made of tiny, flat tiles. It grows in irregular patches that look like cracked paint or a tiled floor on the ground.
Fruiting
Small, sunken black or reddish dots in the center of the scales. These act like "launch pads" to release the lichen's spores.
Growth Habitat & Substrate
Strictly soil-dwelling in dry areas. It grows on dirt or among mosses. Pro tip: if it's on a bare rock, it's a different species.

Care Requirements
Sunlight
Prefers full sun to partial shade, requiring at least 4–6 hours of direct light daily for optimal flowering. Too much shade can lead to reduced blooms and leggy, weak growth.
Temperature
Thrives in warm temperatures, ideally between 18–25°C. Can withstand brief cool periods but is sensitive to prolonged frost or extreme heat, which may damage foliage.
Nutrient
Benefits from a balanced, slow-release fertilizer applied in early spring. Avoid overfeeding, which can promote excessive foliage at the expense of flower production.
Soil
Grows best in fertile, well-drained soil enriched with organic matter. Avoid heavy clay or poorly drained sites, as standing water can cause root rot.
Maintenance
Low-maintenance perennial. Remove spent flower spikes and damaged leaves to encourage new growth. Mulch annually to retain moisture and suppress weeds. Divide clumps every few years if overcrowded.
Water
Requires moderate watering with good drainage. Allow the soil to dry slightly between waterings. Tolerates brief dry spells once established, but avoid waterlogged conditions.

Seasonal Behavior
Spring
Spring triggers vigorous new growth and the emergence of tall flower spikes. This is the main period for active development and the ideal time for feeding and dividing established clumps.
Autumn
Growth slows in autumn as temperatures decline. Leaves may yellow and begin to die back as the plant redirects energy to its roots in preparation for winter dormancy.
Winter
Dormant in winter, with foliage dying back in colder climates. Apply mulch around the base to protect roots from frost. Prune dead stems in late winter before new growth emerges.
Summer
Tolerates summer heat well if watered regularly. Prolonged drought may cause wilting or leaf scorch, but established plants recover quickly once moisture returns.
