When sourcing Small White Pampas Grass, the primary quality indicators are plume density, shedding rate, and stem durability. High-quality specimens should have full, fluffy plumes that do not appear 'thin' or 'patchy.' It is essential to verify the preservation method (natural dried vs. preserved with chemicals) as this affects the shelf life. Ensure the color consistency is uniform across the batch, avoiding yellowish tints unless specified, and confirm the stem length meets your specific retail or event requirements (typically 45cm to 60cm for 'small' varieties).
