SWORD: MIX - TRUE AQUATIC MD
The Amazon Sword Plant is a Rosette plant that is very popular with aquarium hobbyists. The Amazon Sword has several different geographic varieties that vary in leaf size and shape. One variety, Echinodorus bleheri has broad leaves. Another variety, Echinodorus amazonicus has narrower leaves, for example. But either way, the varieties of this plant can be a great addition to a freshwater aquarium. They are capable of reaching approximately 20 inches in height under proper water conditions, making them ideal for larger, deeper aquariums. The Amazon Sword Plant has short rhizomes, numerous lance shaped leaves that are pale to dark green with sharply pointed tips, and fairly short stems. It is an amphibious plant that will grow either partially or fully submersed.
For the most beautiful Amazon Sword Plants, a loose substrate and an iron-rich fertilizer must be used. The Amazon Sword Plant requires at least 2 watts per gallon of full spectrum lighting (5000-7000K). The aquarium temperature should be from 72°-82°F, with an alkalinity of 3 to 8 dKH and a pH of 6.5-7.5. Propagation is by adventitious plants on the covered peduncles.
Best cultivated in large aquariums, Amazon Sword Plants make a great focal point if used singly. When used in groups, they create an interesting background when grown with other aquarium plants.
