Sagittaria

The Sagittaria genus includes approximately 20 perennial aquatic or marsh herbaceous plant species. The leaves are collected in a basal rosette. In aquatic species, there are three types: underwater - ribbon - shaped, floating-long-stemmed, oval or egg-shaped, and aerial-arrow-shaped, which is reflected in the name of the plant. The flowers are unisexual, in rare racemes, and bloom in summer. Plants are fixed in the bottom with the help of shoot-forming rhizomes, due to the rapid development of which the reservoir becomes overgrown. Broadleaf Sagittaria latifolia has light green leaves that are egg-shaped and arrow-shaped. The central part of the white flowers is greenish-yellow. Young plants usually have only linear leaves, and they are used in aquariums. In the pool, the plant height can reach 1.2 m. Common arrowhead (S. sagittifolia) is widespread everywhere in reservoirs with stagnant and slow-flowing water, along the banks of rivers and lakes. It grows rapidly and forms extensive thickets. The leaves are light green, airy, located above the water-large arrow - shaped. The flowers are pinkish-white. In various forms, the flowers are white and even terry. The leaves are darker. Arrowhead grass (S. graminea) is a tender species grown as an annual in climates with cold winters. Leaves above water are linear or egg-shaped. The diameter of white flowers is 1-2 cm. They are collected in groups of 5-7 on erect flowering stems. There are only two varieties: the 'Broadleaf' has longer stem than the botanical species; 'Teres' is a plant with cylindrical, leaf-like expanded and usually flattened petioles and unicolored bracts.

Cultivation

Arrowhead is a widely grown aquatic plant for ponds, swimming pools, and aquariums. It is planted in the ground at the bottom of the reservoir in spring or even in summer (if possible, if plant replacement is required). The soil at the bottom is filled with turf and sphagnum peat, organic fertilizers are added: 200-300 g per bucket of the mixture. New plants are placed on the bottom and buried for 5-10 cm, observing a distance of 20-40 cm between them. The depth of the reservoir used for planting can vary depending on the type: from 10 cm to more than 1 m. The optimal depth of the reservoir, which is required by the archer, is 50-60 cm.

Location

Bright, sunny, open space.

Temperature

With the exception of arrowhead grass, all species are resistant to both high and low air temperatures.

Care

In adult plants, the leaves that have dried up over the winter are removed.

Reproduction

Arrowhead leaves form long shoots by autumn, with tuberous formations at the ends. In the spring, new plants develop from them.

Diseases

Often the leaves and shoots of the arrowhead are affected by Rophalosiphum nimphaea, sucking out the sap. Instead of treating them with insecticides that pollute the water, they knock insects off plants with a strong water jet.

Acquisition

Arrowhead plants are easily found in nurseries that specialize in growing aquatic plants. Choose well-formed and healthy specimens.

Gentle views: how to protect them from frost Among the less common species of the Arrowhead genus, there are delicate, sensitive plants. These include the herbaceous arrowhead and Guiana arrowhead (s. guyanensis), large-leaved arrowhead (S. macrophylla), lanceolate arrowhead (S. lancifolia) and Montevidean arrowhead (S. montevidensis). In moderately cold climates, they are usually used only for aquariums or as annuals. If you want to grow these species in the fresh air, and also save them for the next year, it is recommended to plant arrowheads in small tanks, which can be easily removed to a closed heated room, in which it is possible to maintain a temperature of at least 10 °C.
