Sagittaria platyphylla

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Best placed in the midground or background due to its larger size and broader leaves. It works well as a solitary accent plant or in small, spaced groups. Allow sufficient room around it, as it can cast shade on smaller foreground plants.

Botanical form

Rosette

Characterized by stiff, broad, strap-like leaves that grow in a rosette pattern. The submerged leaves are typically a bright, fresh green and somewhat fleshy. It has a more substantial presence than S. subulata.

Growth

Medium

Exhibits a moderate growth rate, focusing its energy on producing sturdy leaves and a strong root base. Growth is steady in most setups, accelerating slightly with a nutrient-rich substrate. It is less invasive than other Sagittaria species.

Substrate

High

Column fertilization

Recommended

Benefits from occasional liquid fertilization, particularly for trace elements. However, it relies more on root uptake than water column feeding. Ensure adequate potassium in the water column to prevent pinholes in its broad leaves.

Root fertilization

None

Heavily dependent on substrate nutrition for optimal health. Using a quality aquasoil or supplementing with root tabs is highly recommended. A deep substrate allows its extensive root system to anchor securely.

Trimming

Occasional

Pruning involves removing older or damaged leaves at their base near the crown. Avoid cutting leaves mid-way, as the remaining portion will slowly decay. Thin out runners if the plant begins to encroach on unwanted areas.

Propagation

Runners

Propagates via runners, though less aggressively than S. subulata. Small plantlets will develop around the base of the mother plant. These can be separated and replanted once they have established a decent root system.

Sensitivity

Moderate

Very hardy and forgiving, making it an excellent choice for novice aquarists. It tolerates a wide range of water hardness and pH levels. Can be susceptible to spot algae on older leaves in high-light, slow-growth conditions.

Layout role

Midground

Serves as a strong structural element in the midground, offering a contrast to finely textured plants. Its broad leaves create a bold, tropical look. Often used to provide hiding spots for fish and invertebrates.
