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. Too much shade can reduce flowering and vigor.
Temperature
Thrives in mild to warm temperatures, ideally between 15–25°C. Sensitive to frost and extreme heat.
Nutrient
Benefits from balanced, slow-release fertilizer in spring. Over-fertilizing can reduce flowering and promote excessive leafy growth.
Soil
Prefers well-drained, fertile soils with organic matter. Avoid heavy clay or waterlogged conditions.
Maintenance
Low-maintenance perennial. Prune lightly after flowering to shape and remove dead stems. Mulch annually to retain moisture.
Water
Needs moderate watering, allowing the soil surface to dry slightly between waterings. Tolerates short dry spells but not prolonged drought.

Seasonal Behavior
Spring
Spring triggers new shoots and flowering. This is the main period of active growth and the best time for shaping and feeding.

Autumn
Growth slows in autumn as temperatures drop. Leaves may take on reddish hues before falling, and the plant prepares for winter dormancy.

Winter
Dormant in winter, with little visible growth. Protect from harsh frost with mulch at the base, and prune only if necessary in late winter.

Summer
Tolerates summer heat if watered regularly. Prolonged drought may cause leaf drop, but established plants recover quickly after rain.
