Acidic family. Homeland - both tropical, subtropical and temperate areas on all continents. About 800 species of representatives of this genus are common in nature. These are medium-sized herbaceous perennials and annuals.
- Deppe's sourness Oxalis deppei is a small stemless shrub with a dark brown bulb and underground shoots. Leaves on thin and long petioles of 4-6 pieces are collected in rosettes. The leaves are palmately compound, with four segments, each inversely heart-shaped, up to 3.5 cm long, notched at the apex and finely serrated at the margin. The leaves are light green with a purple spot in the center, and fold when dark. Flowers up to 2 cm in diameter, red or with a purple tint, with a yellow pharynx, collected in an umbrella-shaped inflorescence. Fruit box.
- Oxalis ortgiesii is a small herbaceous plant with pubescent stems, at the apex of which leaves are mainly formed. The leaves are ternate, each of leaflets up to 7 cm long, inversely heart-shaped, with a deep notch at the apex, brownish red with pubescence. Flowers up to 1.5 cm in diameter, yellow, collected 5-10 pieces in an umbrella-shaped inflorescence.


Care for acidity
Temperature: Moderate. Ortgiz sour is found at 16-18 ° C in winter. During the dormant period, Deppe's acidity loses leaves, so pots with its bulbs are kept in a cool place at a temperature of about 8-10 ° C.
Lighting: Very bright place. It should be noted that acidity needs very intense lighting, but direct sun from noon can cause burns. Therefore, it prefers the eastern orientation of the windows. The south and west window (or balcony side) will need light shading.
Watering: In summer, during active growth, watering is plentiful. Since autumn, watering is reduced. Ortgis acid is rarely watered in winter, preventing the soil from only completely drying out. Deppe's nodules of sourness are stored in a cool room, so you don't have to water them for 1.5 months of rest.
Fertilizer: From April to August, sour is fed with liquid fertilizers for indoor plants. Feeding is carried out in two to three weeks.
Humidity: In spring and summer, it is necessary to spray regularly. But if the humidity is not lower than 45%, the sour is quite complete without moisture.
Transplantation: Annually in spring into a light soil mixture consisting of 1 part of turf, 1 part of leaf, 2 part of peat, 1 part of humus and 1 part of sand.
Reproduction: Propagated in nodules.
