Plants of the Buckwheat family have presented people with many useful and tasty products, including the beloved buckwheat and vitamin stems and leaves of Rhubarb. Moreover, Rhubarb is not only useful for the human body, but also very decorative, and therefore will willingly become a decoration of the suburban area
Rod Rhubarb
Fifty species of herbaceous rhizome perennials are combined into the genus
Rhubarb (Rheum).
The Almighty endowed them with a mass of abilities that are in demand by man. Rhubarb is cultivated as a vegetable crop; it is used in healing procedures; the tannins of the plant are used in leather dressing; the decorative appearance of large leaves adorns garden beds and summer cottages.
Long-stemmed large leaves form a picturesque basal rosette. The bright color of the underside of the leaves gives the leaves a special charm.
Half-meter erect peduncles show the world of inflorescences-panicles or inflorescences-ears, collected from small flowers. The appearance of the inflorescences, with its nondescriptness, does not add decorativeness to the plant, but serves the continuation of the life of the genus.
Varieties
* Black sea rhubarb (Rheum rhaponticum) is a tall plant up to one and a half meters high with a picturesque root rosette of leaves and yellowish flowers.
* Palm-shaped rhubarb (Rheum palmatum) is a giant plant up to 4 meters high. Its huge leaves are arranged on ribbed fleshy petioles. The reverse side of green leaves with a purple tint.
* Rhubarb cultural (Rheum x cultorum) - it is assumed that this species is a hybrid brainchild of the two species described above. Edible leaves sit on long petioles, the underside of which is protected by light pubescence. Pale yellow flowers bloom in summer.
* Alexander's rhubarb (Rheum alexandrae) - a relatively low species up to 1.2 meters high. From the short rhizome, the roots of the plant penetrate deep into the soil. The short petioles hold green ovoid leaves with a glossy surface. At the beginning of summer, panicle inflorescences with large yellowish-cream bracts bloom, crawling over each other and giving decorative effect to the bush.
* Noble rhubarb (Rheum nobile) - the name very closely matches the appearance of the plant. Somewhere in the Himalayas stands a kind of lonely two-meter handsome man, full of courage and nobility, covering the ground with his rounded leaves and showing cream-colored flowers in summer..
* Rhubarb officinalis (Rheum officinale) - a popular ornamental plant with whole leaves growing up to a meter in length, rises to the sun to a height of 3 meters. Small greenish-white flowers gather in dense panicle inflorescences, appearing in the world in summer. This type of Rhubarb has healing properties, helping the healthy functioning of the human digestive system.
Growing
Growing Rhubarb is considered to be of medium difficulty, although the plant does not make any special claims to the gardener.
A sunny place is better suited for him, but in partial shade it will grow without problems. The culture is winter-hardy. Actually, only the rhizome has to overwinter, since the aboveground part of the plant dies by winter.
The soil for Rhubarb needs fertile, fertilized with organic matter, loose, non-acidic, moist, but without stagnant water. Summer watering of the plant is abundant.
Reproduction
Two types of reproduction are practiced:
1) sowing seeds, which can be carried out in the spring immediately in the open field;
2) division of an adult bush, or rather, its rhizomes. Each part must have its own roots and at least one living bud.
Enemies
Rhubarb, as a rule, does an excellent job with potential enemies, not succumbing to their provocations.
The weak point of the plant is its roots, which, with an excess or stagnation of moisture in the soil, can become covered with mold, which will further affect the entire plant.
In addition, harmful insects living in the soil sometimes feast on roots, gnawing them so hard that the plant loses its nutrition and dies.
