7cm（WYSIWYG）Lophophora diffusa 5 years old Number 521

Lophophora diffusa is a rare and visually distinctive spineless cactus, highly valued by collectors for its soft, velvety appearance and pale coloration. Native to limited regions in Mexico, this species forms a flattened, globular stem with a distinctive yellow-green to sea-green hue. Its surface is divided into rounded, hump-like ribs adorned with patches of soft white woolly areoles, giving it a gentle, almost cloud-like texture.
