Nomaphila stricta

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Because of its broad, commanding leaves and thick stems, it is best placed in the background of the aquarium. It can quickly overshadow smaller foreground or midground plants, so giving it ample space is important. In very large tanks, it can be used to create a striking midground focal point.

Botanical form

Stem

It features very sturdy, thick stems and exceptionally large, bright green leaves that are broadly lanceolate. The leaves grow in opposite pairs and can reach several inches in length. When it reaches the water's surface, it readily adapts to emersed growth and may produce attractive purple flowers.

Growth

Medium

The growth rate is very fast, especially under good lighting and nutrient-rich conditions. It will quickly grow toward the surface, often requiring weekly trimming to keep it from blocking light to the rest of the tank. It grows well even without CO2 injection, though the leaves will be slightly smaller.

Substrate

High

Nomaphila stricta is a robust, fast-growing plant that thrives in a rich, deeply layered substrate capable of supporting its massive root system. The roots play a vital role in stabilizing its tall, rigid stems and absorbing the heavy amounts of macronutrients needed to grow large leaves. A substrate bed of at least 3 to 4 inches made of an active aquasoil or nutrient-enhanced gravel is essential for long-term success. Providing additional fertilization at the roots via capsules or tabs ensures the plant does not experience nutrient deficiencies as it matures.

Column fertilization

Recommended

Liquid fertilization is highly effective and recommended for this fast-growing plant. Regular dosing of a complete fertilizer ensures that the water column has sufficient potassium to prevent leaf degradation. It is a robust plant that can handle and utilize high nutrient loads, making it great for newer setups.

Root fertilization

Recommended

'Stricta' develops a massive, deep root system that helps anchor its large structure. Providing a nutrient-rich substrate or adding root tabs will result in significantly thicker stems and larger, healthier leaves. The strong root system also means that uprooting the plant can disturb a large area of the substrate.

Trimming

Occasional

Frequent pruning is a necessity. You can simply cut the stem at the desired height; the lower portion will usually develop multiple new side shoots, creating a bushier plant. Because the stems are quite thick and tough, use sharp aquascaping scissors to make clean cuts and avoid crushing the tissue.

Propagation

Cuttings

Propagation is extremely simple: just take a stem cutting and replant it in the substrate. The cutting will quickly root and begin growing within a matter of days. You can also replant the tops that you remove during regular maintenance to expand your stand.

Sensitivity

Moderate

This is an incredibly robust and adaptable plant that easily forgives beginner mistakes. It tolerates a wide range of water hardness and pH levels without issue. Its only real vulnerability is a lack of basic macronutrients, which it clearly signals through the deterioration of its older leaves.

Layout role

Midground, Background, accent

It serves as a fantastic, fast-growing background plant that provides dense coverage and a lush, jungle-like aesthetic. Its broad leaves offer excellent hiding places for fish and help break up the sightlines in the tank. It is also a very effective nutrient sponge, helping to keep the water clean and algae-free.
