Aristolochia

The genus Aristolochia includes approximately 350 species of perennial climbing herbaceous and shrubby, evergreen and deciduous plants. These cultures are characterized by single and grouped flowers of original shape, curved-tubular, without clearly marked calyx and corolla. Widely used for decorative purposes, the species is Aristolochia elegans, a climbing tender evergreen plant with large heart-shaped green leaves. The flowers have a yellow tubular part, with a purplish-brown tip and white veins; they bloom from July to September. Large-leaved Aristolochia (A. macrophylla, or A. durior) grows up to 10 cm in height. It has large heart-shaped leaves and yellow, brown or green flowers that bloom in May. It is light-loving and tolerates partial shade. Aristolochia Manchu (A. mandschuriensis) - up to 14 m high, characterized by greater winter hardiness than the previous species. Aristolochia large-flowered (A. grandifiora) has large purple flowers with lighter spots; however, they have a disadvantage - a very unpleasant smell, so it is recommended to grow them away from housing. Aristolochia trilobata (A. trilobata) is a climbing unstable species with deeply divided leaves. The flowers are solitary, green with brown spots, the apical lobe and "tail" are dark brown. Aristolochia clematis (A. clermatitis) is a herbaceous stable perennial spreading rhizomatous species. Non-branching stems reach a height of 1 m. The leaves are heart-shaped filmy. Flowers are greenish-yellow, collected in axillary groups. Round Aristolochia (A. rotunda) is used for breeding new garden forms. It has velvety thimble-shaped flowers with a very dark lip, blooming in June. Aristolochia salpinx (A. salpinx) is a delicate botanical species, interesting for its large flowers blooming in summer.

Cultivation

Aristolochia is used for vertical gardening, decoration of walls, trellises and pergolas. They can also be grown in pots on balconies and terraces, especially elegant aristolochia. In moderately cold climates, plants are insulated for the winter: after pruning in autumn, the vine is laid on the ground and covered with insulation material or snow. Plants are planted permanently in September (if the winter is cold) or in April. They prefer loose, nutritious soil. During planting, it is recommended to apply organic fertilizers. When growing in a pot, use fertile land (2/3) and peat (1/3) with the addition of a complex fertilizer at the rate of 30 g per bucket of soil. Then, once a month, a complete mineral fertilizer is added to the water for irrigation in the amount of 10 g per bucket. Young plants are pruned immediately after planting, which contributes to better tillering - the branches are shortened by about a third of their length.

Location

Aristolochia can be planted both in the open sun and in partial shade.

Temperature

There are stable species-large-leaved aristolochia and clematis aristolochia, which tolerate temperature fluctuations well, as well as gentle ones (elegant aristolochia and three-lobed aristolochia), which cannot withstand temperatures below 10 °C.

Watering

Spring and summer should be watered abundantly and regularly, primarily potted plants. In autumn and winter, it is enough to keep the soil slightly moist.

Transplant

Aristolochia can be transplanted even annually, in the spring. If the size of the pot is large, it is recommended to limit yourself to replacing the surface layer of the earth.

Reproduction

Propagate by offspring, layers, seeds. Sowing is carried out in March or later-in April, in a special soil for seeds, maintaining the temperature at 14-16 °C (for Aristolochia elegant 22-24 °C). Grown seedlings are transplanted into pots one at a time, and then soon planted in the ground in the fresh air. Layers and offspring are propagated in summer and autumn.

Diseases

Various fungi provoke the appearance of spots on the leaves. Usually, in such cases, they are limited to removing the affected parts of plants. If the disease has become widespread, treatment with captan-containing drugs is carried out.

Acquisition

Aristolochia can be found in well-stocked specialized nurseries and horticultural centers. Plants are recommended to be purchased in the fall or spring, depending on when you are going to plant them completely. Indoor aristolochia elegant in a pot can be bought at any time of the year.
