Echinodorus 'Red Diamond'

Geographical Origin and Habitat: Echinodorus 'Red Diamond' is a hybrid cultivar created in Europe through horticultural selection programs in greenhouses. It is not found in the wild. The genus Echinodorus is native to the tropical and subtropical territories of the Americas, populated by waterways and marshes. This variety was developed to combine the elongated leaf shape typical of Echinodorus uruguayensis with a particularly intense ruby-red

Color & Texture: ation and a compact size suitable for medium-sized aquariums.

Taxonomy & Genetics: It belongs to the family Alismataceae and is a selected cultivated hybrid. Its complex genetics contain characters of pure species known for chromatic intensity, such as Echinodorus uruguayensis and other red hybrids. The 'Red Diamond' variety was selected to maintain the brilliant red coloration on the new leaves and ruby shades on the adult leaves, distinguishing itself by its compactness and stability of characters. It propagates vegetatively to keep the clone pure.

Physical Structure: It forms an erect and exceptionally dense rosette, which reaches a height between 15 and 25 cm in the aquarium, exceptionally 30 cm. Submerged leaves are lanceolate or elliptical, supported by short and robust petioles that keep the rosette dense and symmetrical. It develops a short, woody rhizome and a vigorous root system that anchors firmly in the aquarium substrate.

Color & Texture: New leaves emerge from the center with an extremely intense, glossy, and spot-free dark ruby-red coloration. Over time, mature leaves take on greenish-brown or dark olive-green shades, while retaining the main red or orange veins that create an exceptional visual effect. The leaf blades have smooth margins and a leathery, robust texture.

Lighting & CO2: Requires medium to high lighting. To maximize the development of the ruby-red pigmentation and prevent the plant from growing with overly long petioles, it is essential to provide intense light. CO2 injection is recommended to promote robust growth and to keep the leaves thick and compact, accelerating the development of the clump.

Nutrition & Substrate: It is a heavy feeder of root nutrients. Requires a fertile substrate enriched with slow-release fertilizer tabs rich in iron and trace elements inserted regularly near the roots (every 3-4 months). A nutrient deficiency quickly causes new leaves to emerge pale, small, and fragile.

Water Chemistry: Adapts to a wide range of values, with ideal temperatures between 15°C and 30°C. The preferred pH is acidic or neutral (5.0 - 7.0), with water hardness from soft to medium (KH 1-12 dKH). Benefits from good filtration and regular partial water changes to keep the environment free of excess organic substances.

Space Management & Placement: Its ideal placement is in the midground of the aquarium, or in the background of small to medium tanks. Thanks to its compact size and extraordinary red coloration, it serves as a beautiful solitary focal point (solitary plant). It should be positioned leaving enough space around it so that it can showcase its symmetrical rosette without being shaded.

Pruning: Pruning consists of the periodic removal of older or damaged leaves at the base of the rosette. Cut leaves close to the rhizome using sharp scissors. This stimulates leaf replacement with new red central leaves and prevents the decay of the rosette's appearance. Remove any flower stalks if you want to concentrate energy on the leaves.

Risks & Diseases: It is sensitive to chlorosis due to lack of iron. The thick, moderately growing leaves can be prone to colonization by black brush algae or green spot algae if there are nutrient imbalances or fluctuations in CO2 levels in the aquarium. Additionally, young leaves are tender and can be damaged by herbivorous fish.
