Distribution of Mariola
Distribution Map
Mariola is a plant originally endemic to the desert and scrub regions of the North American continent, predominantly in the southwestern areas. Despite its limited native range, mariola has seen some spread beyond these boundaries, adapting to similar arid habitats elsewhere. Its tolerance to harsh conditions allows it to colonize and thrive in comparable climates across various geographies.

Water:
Mariola thrives in semi-arid environments, showing resilience to drought with minimal watering needs, ideally once a week. It prefers full sun and well-draining soil to prevent waterlogging, mirroring its natural habitat's conditions.
Fertilize:
For optimal mariola growth, use balanced fertilizers at quarter strength monthly during active growth. This promotes health, flowering, and drought resistance. Avoid over-fertilization to prevent root burn and adjust feeding during dormancy. Post-fertilization, ensure thorough watering.
Pruning:
Mariola is a perennial shrub with aromatic leaves and white flowers. Prune in early to late spring by removing dead branches and thinning for light. Regular pruning boosts blooming and maintains size; ensure clean cuts to prevent disease and avoid excessive pruning for natural shape.
Propagation:
Mariola is native to arid regions, thriving in well-drained soils. Propagate by surface-sowing seeds in sandy mixtures, keeping soil moist but not waterlogged. Light is essential for germination, with seedlings transplantable once they develop strong root systems.
