Broad Leaf Chain Sword
Helanthium bolivianum 'Latifolius'
Plantae›Tracheophyta›Liliopsida›Alismatales›Alismataceae
📍 South America
Broad Leaf Chain Sword is a hardy, easy carpeting and midground plant with broader, lance-shaped green leaves — fuller and a touch taller than the grassy narrow-leaf chain swords. It spreads by runners that form connected “chains” of plantlets, quickly filling an open midground or a tall foreground carpet. Undemanding and beginner-friendly: it grows without CO₂ under low-to-medium light, though richer substrate, added CO₂, and brighter light produce a denser, faster carpet.

Pairs well as a complementary carpeting/midground plant with similar care
Common Diseases
Melt on Transition
Leaves turn translucent, mushy, and dissolve within days of planting; typical when moving from emersed to fully submerged growth.
Trim affected leaves; keep parameters (pH, temperature) stable; provide adequate light and nutrients; be patient as new submerged growth emerges.
Iron Deficiency (Chlorosis)
New leaves appear pale yellow or white while veins stay green.
Dose chelated liquid iron; ensure macronutrient balance to improve iron uptake; raise light if deficient.
Algae Overgrowth on Leaves
Green, brown, or black algae coating leaf surfaces; stunted growth.
Cut photoperiod to 8–10 hrs; increase water changes; add algae eaters (Amano Shrimp, Otocinclus); improve flow.
Nutrient Deficiency (Macronutrient)
Stunted growth, yellowing older leaves, weak runner development.
Dose an all-in-one liquid fertilizer or macro supplement; use nutrient-rich substrate or root tabs; increase water-change frequency.
