General Description
Isoetes velata var. sicula is a species of quillwort, belonging to the ancient group of Lycophytes. These reed-like plants with bulbous stems are typically found in wet habitats or aquatic environments. With around 60-150 species worldwide, Isoetes shares ancestry with extinct Palaeozoic trees like Sigillaria and Lepidodendron, making it a unique and fascinating addition to botanical collections.
Aquarium Suitability
Available occasionally in the commercial market, Isoetes velata var. sicula is a sought-after plant by aquarists due to its rarity and intriguing characteristics. While there are several Isoetes species suitable for aquariums, this particular variety is more commonly cultivated, especially in regions like Germany. Its slow growth and adaptability to various water parameters make it a suitable option for aquaria settings.
Demands and Hardiness
Considered an easy plant to care for, Isoetes velata var. sicula thrives in nutrient-rich substrates such as sand or fine gravel mixed with loam. It can tolerate a wide range of water conditions, including medium to high lighting levels and a temperature range of 22-26°C. With moderate demands for carbon dioxide and nutrient levels, this plant is a great choice for aquarists looking to add an uncommon yet resilient species to their tanks (see table for more details).
Aquascaping & Usage
Ideal for background or midground placement, Isoetes velata var. sicula can be utilized in nano tanks or as a striking specimen plant. Its rosette growth habit adds a unique dimension to aquascaping, enhancing the visual appeal of aquatic landscapes with its grass-green foliage and bulbous rhizome structure.
Propagation
Propagation of Isoetes velata var. sicula can be achieved through spores, splitting, or cutting off daughter plants. While spore propagation is more intricate due to the heterospory nature of the plant, the process can be rewarding for dedicated aquarists looking to expand their collection through sustainable means.
Habitat and Distribution
Native to locations in South Europe, specifically Sicily and Sardinia, Isoetes velata var. sicula thrives in habitats that mimic its natural environment. Growing in cold lakes with low nutrient levels, this species adapts well to aquatic conditions and can be found in regions where its unique biological characteristics contribute to the biodiversity of the ecosystem.
