Cryptocoryne willisii T/C Cup is a tissue-cultured aquatic plant featuring compact rosette growth and slender, fresh green leaves. Its smaller size makes it ideal for foreground and lower midground placement, where it can gradually develop into attractive, natural-looking groups. This hardy Cryptocoryne performs well under low to moderate lighting and generally does not require supplemental CO₂, although CO₂ and balanced nutrients can encourage denser growth. Before planting, remove the plant from the cup, thoroughly rinse away the culture gel, and divide it into several small portions. Plant directly into a nutrient-rich substrate. Once established, it provides reliable greenery, subtle texture, and a clean natural appearance.
