Cryptocoryne hudoroi

IntermediateFreshwater

Origin: Cryptocoryne hudoroi is a rare species from southern Borneo (Kalimantan), where it grows in limestone rivers with fast flow, forming dense submerged stands. It was described by Bogner and Jacobsen.

Overview

Cryptocoryne hudoroi is a striking but uncommon crypt with blistered-crinkled (bullate) leaves that in young plants often carry a reddish-bronze tone. It likes flow and somewhat hard water, reflecting its natural biotope in limestone rivers. It grows under moderate light and is quite hardy for a rare species. It forms midground rosettes and spreads by runners. Like all crypts it may 'melt' under a sudden change of conditions, but recovers.

Appearance

A rosette of petioled leaves: the blade is elongate-lanceolate with a pronounced blistered-crinkled surface, 15–25 cm long. Young leaves are reddish-bronze, mature ones dark green. Height is 20–30 cm. It produces runners with daughter rosettes.

Care

Moderate light, 18–30 °C, pH 5.0–7.5, tolerates somewhat hard water (KH 2–12) and flow. CO2 is optional but improves growth. Nutrient-rich substrate is needed. It is quite hardy for its rarity.

Fertilizing

It feeds mainly through roots: nutrient-rich substrate and root tabs matter. Moderate nutrient demand.

Breeding

It propagates by runners with daughter rosettes, separated once rooted. It spreads gradually.

Fun facts

Cryptocoryne hudoroi was described by Josef Bogner and Niels Jacobsen and brought into cultivation in the 1990s. The young bullate leaves with a reddish-bronze tone are especially decorative. It is a rare species from a limited number of Borneo localities.
